Welcome to Desktop Paint 256...


WHAT IT IS
__________

Desktop Paint 256 is a full colour bitmapped paint program
written to use the extended resolution of super VGA cards. It
features a mouse driven user interface, full colour manipulation
and drawing tools and a choice of popular image file formats.
Desktop Paint 256 supports the following image file formats:

    - PCX (As used by ZSoft's PC Paintbrush)
    - GIF (As used by CompuServe)
    - IFF/LBM (As used by Electronic Arts' Deluxe Paint)
    - TIFF

Note that Desktop Paint 256 will work with image files having
between two and 256 colours. However, if you're working with two
colour... monochrome... graphics, you'll find that our monochrome
Desktop Paint package is better for handling them. It's faster,
requires much less memory and has tools designed for monochrome
applications.

Desktop Paint 256 is a paint program, rather than a drawing
program. It does not support GEM, Corel Draw, Designer, DXF or
EPS files.

Unlike many other paint programs, Desktop Paint 256 features
complete EMS and XMS support. It will handle enormous images...
pictures which unpack into several megabytes... if you have
sufficient expanded or extended memory in your system. Note that
you must have at least 300 kilobytes of EMS or XMS to edit a 640
by 480 pixel picture under Desktop Paint 256.

HARDWARE REQUIREMENTS
_____________________

You can theoretically run Desktop Paint 256 on an 8088 based
system, although it will be very slow and cumbersome. We
recommend at least an 80286 system. An 80386 system will improve
its performance considerably.

Desktop Paint 256 requires a Microsoft compatible mouse and driver
and one of the following super VGA display adapters:

    - Paradise Plus (256K on board)
    - Paradise Professional (512K on board)
    - ATI VGA Wonder card (256K or 512K on board)
    - Headland Video7 or 1024i card (256K or 512K on board)

Cards which are genuinely compatible with these cards are also
suitable... for example, there are numerous cards which use the
Western Digital chip set and are thus effectively Paradise cards.
The OEM VGA cards supplied with Dell computers behave as Paradise
cards, for example.

Desktop Paint 256 does not run in the "standard" 320 by 200 pixel
VGA mode.

If you have access to several machines, you might want to note
that the Paradise card driver will allow Desktop Paint 256 to run
considerably faster than will the drivers for the other super VGA
cards it supports, due to the internal workings of Paradise
cards.

You should have a full 640 kilobytes of main memory to run
Desktop Paint 256... you can get by with as little as 384
kilobytes if you will be working exclusively with very small
images, but it's not recommended.

For practical purposes, you will probably want to have some extra
memory in your system... either expanded (EMS) memory or extended
(XMS) memory. In order to work on 640 by 480 pixel images... a
commonly found size... a minimum of 300 kilobytes of available
extra will usually be required to use all the features of Desktop
Paint 256.

You may be able to get by with no extra if you'll be working with
smaller files. See the discussion about memory later in this
file.

If you wish to use Desktop Paint 256 with graphics files in
formats other than those it currently supports, we recommend that
you get a copy of Graphic Workshop, which will convert among
virtually all of the popular image file formats. See the end of
this file for more information about Graphic Workshop.


CONFIGURING DESKTOP PAINT 256
_____________________________

Desktop Paint 256 will not run until it has been configured.
Among other things, configuring it supplies it with a driver that
will suit your particular display card. You must know your
display card type before you configure Desktop Paint 256... the
configuration program cannot figure it out for you.

Here are the names of the drivers supplied with Desktop Paint and
the display cards they correspond to:

    PARA400.DRV    - Paradise Plus (256K on board)
    PARA480.DRV    - Paradise Professional (512K on board)
    ATI400.DRV    - ATI VGA Wonder card (256K on board)
    ATI480.DRV    - ATI VGA Wonder card (512K on board)
    HEAD400.DRV    - Headland Video 7 (256K on board)
    HEAD480.DRV    - Headland Video 7 or 1024i (512K on board)

You should place the following files in the directory you plan to
keep Desktop Paint 256 in.

    - DTP256.EXE    The program
    - DTP.RES    Fonts and other resources
    - DTPCINST.EXE    The installer
    - EXAMPLE.PCX    A picture file
    - *.DRV        The appropriate driver

Note: The DTP.RES file provided with Desktop Paint 256 is
identical to the one used by monochrome Desktop Paint, and the
two programs can share the same DTP.RES file. Those resources
specific to one will be ignored by the other. You can install
both programs in the same directory and save a few hundred
kilobytes of disk space if you like by giving them a common copy
of DTP.RES.

To configure Desktop Paint 256, run DTPCINST.EXE. It must reside
in the same directory as DTP256.EXE. You will see a screen like
this one:

   Desktop Paint 256 installer version 1.2                 RUN TIME DEFAULTS

            Default file type: PCX
           PCX file extension: PCX
           GIF file extension: GIF
       IFF/LBM file extension: LBM
          TIFF file extension: TIF
                 Extra memory: DOS
 EMS/XMS overhead (kilobytes): 256
              Default printer: PostScript 100 DPI
            Default New width: 640
            Default New depth: 480
                    Drive map: ABCDEFGH
              Path to DTP.RES:
           Screen driver path: DRIVR256.DRV
         Default smudge value: 3
                  TIFF colour: COLOUR
          TIFF grey expansion: NO
              Registered name: [ Unregistered ]
            Registration code: 00000


You can change the values in any field by cursoring down to it
and hitting Enter.

Here's a quick overview of what the fields in the installer do.

    Default file type:
This line sets the default file type which Desktop Paint 256 will
initially use to open and save files with. Keep hitting Enter
until the one you want appears.

    PCX file extension:
    GIF file extension:
        IFF/LBM file extension:
        TIFF file extension:
These lines allow you to change the file extensions with which
Desktop Paint 256 will look for each of its image file types. You
can usually leave these alone.

    Extra memory:
Set this line to tell Desktop Paint 256 whether you have EMS or
XMS memory available. Make sure you set this to EMS or XMS if you
have extra and want to work with large pictures. Make sure you
choose the appropriate type of extra memory for your system or
Desktop Paint 256 may crash. If you're running Desktop Paint
under Windows 3, use XMS.

    EMS/XMS overhead (kilobytes):
This line tells Desktop Paint 256 how much free DOS memory to leave
if it has EMS or XMS available. If this value is set to 256... two
hundred and fifty-six kilobytes... any picture which would leave
less than 256 kilobytes of free DOS memory were it to be loaded
would instead be loaded into extra memory. If EMS or XMS are not
enabled, this value is ignored. You can probably leave this value
alone initially.

Increase this number if you start running into memory problems in
Desktop Paint 256 when you're editing large files and you have
EMS or XMS.

    Default printer:
This line sets the default printer. Do not set it to "Dot matrix"
unless you will have a PDRV resource loaded into DTP.RES, as
described below.

    Default New width:
This line sets the default width value which appears in the New
box in Desktop Paint 256. This setting can be overridden from
within Desktop Paint 256.

    Default New depth:
This line sets the default depth value which appears in the New
box in Desktop Paint 256. This setting can be overridden from
within Desktop Paint 256.

    Drive map:
This is a string which should contain all the letters of the
legal hard and floppy drives on your system. It should have no
spaces or extraneous characters. This string is not checked for
validity. Change this to suit your system

    Path to DTP.RES:
This should be the complete DOS path to the directory where
DTP.RES will be located on your system. It should include the
drive letter and a trailing backslash. For example,

C:\PAINT\

This string is not checked for validity. If you get it wrong,
DTP.RES will not be loaded when Desktop Paint 256 is run, and you
will have no text fonts.

With this string set correctly, you can run Desktop Paint 256 from
anywhere on your hard drive and still have it find its resource
file. Change this to suit your system.

    Screen driver path:
This must be a complete path to the screen driver for your
display card. For example, if you will be using a Paradise
Plus card... the driver for which is PARA256.DRV... and the
driver will be in the directory \DTP on drive C, you would fill
in C:\DTP\PARA256.DRV in this field.

This field must be correctly filled in for Desktop Paint 256 to
boot up. Its initial contents are a dummy driver name.

    Smudge value:
This affects the amount of diffusion the smudge function will
impose on a selected image fragment. It can range from 1 through
6, where 1 will produce the least amount of smudging. This
setting can be overridden from within Desktop Paint 256.

    TIFF colour:
This setting determines whether TIFF files written to disk from
Desktop Paint 256 will be colour or grey scale pictures. This
setting can be overridden from within Desktop Paint 256.

    TIFF grey expansion:
This setting determines whether TIFF files written to disk from
within Desktop Paint 256 will have linear grey scales or expanded
ones. See the section on TIFF files for more information about
how to use this function. This setting can be overridden from
within Desktop Paint 256.

    Registration name:
    Registration number:
When you register Desktop Paint 256, we'll send you back a number.
Enter your name in the registration name field exactly as it was
when you registered Desktop Paint 256 and your registration number in
the next field. Upper and lower case matter. This will disable
the beg notice at the end of Desktop Paint 256. If your name contains
characters with accents or other non-English characters, please
read ACCENT.DOC for instructions for entering them into the
Registration name field.


RUNNING DESKTOP PAINT 256
_________________________

Once you have configured Desktop Paint 256 with DTPCINST.EXE,
type DTP256. When the program has loaded you'll see a grey screen
with a menu bar at the top. Click on one of the menu items to
pull down a menu. Drag the mouse pointer to the menu item you
wish to select and release it. The function you've chosen will
pop up. (Chances are you already know how to work a menu bar.)

Note that on mice with more than one button, Desktop Paint 256
expects you to use the left one for clicking in controls and
such.

To open a file, you must first tell Desktop Paint 256 which of its
file types you want to deal with using the File Type box of the
File menu. It comes set up to default to PCX files... you might
have changed this when you configured it.

Select the File Type item from the File menu and set the file
type you wish to use. Next, select the Open item and select the
file you want to Open. If you want to start from scratch, select
the New item instead. The New function comes set up to default to
creating 640 by 480 pixel files. You can type in different values
if you like, and these default values can be changed with the
installer program.

A work area will open on your screen. If the picture you want to
work on is too big to fit on the screen all at once, scroll bars
will appear to allow you to move the work area over your picture.

If you wish to open a different picture, you must first select
Close from the file menu to close your current picture and then
select New or Open.

You can return to DOS at any time by selecting Quit from the File
menu.

You can run Desktop Paint 256 and load a file into it with one
command from the DOS prompt. For example, if you wanted to edit a
file called PICTURE.GIF, you could do this

C>DTP PICTURE.GIF

This would run Desktop Paint 256 and load the picture as if it had
been loaded with the Open command from the File menu.

Desktop Paint 256's dialog boxes will respond to the keyboard. If you
hit the Enter key when a dialog box is visible, the box will
respond as if you had clicked in the "Ok" box. If you hit Esc it
will respond as if you had clicked in the "Cancel" box, assuming
there is one.


A WORD ABOUT MEMORY AND DESKTOP PAINT 256
_________________________________________

Desktop Paint 256 is forever calling for and releasing blocks of
memory. Each time it opens a window, displays a picture or an
icon, responds to a mouse click and so on, it calls for at least
a bit of memory.

If you hear a beep when you ask Desktop Paint 256 to do something,
this usually indicates that it could not find enough memory to do
what you asked it. This may be because you're running it in
restricted memory, or because most of your memory is occupied by
a picture.

If possible, you should not run Desktop Paint 256 from a shell
program, or shelled out of another application, as this will
reduce the amount of memory it has available for its own use.

In very cramped memory situations, you can free up a bit of
memory by unselecting an area of your drawing if one is currently
selected. Selecting things will be dealt with later in the
discussion of the Selector tool.

Note that if you attempt to quit Desktop Paint 256 and there
isn't enough memory to open the window that asks "Do you want to
quit?", Desktop Paint 256 will assume that you do and return you
immediately to DOS. As such, you can't actually get trapped in
it.


A WORD ABOUT PICTURE MEMORY
___________________________

A 256 colour picture is stored in Desktop Paint 256 with one byte
of memory for each pixel of the picture. Thus, you can figure out
how much memory is needed for basic storage by simply multiplying
the dimensions together. A 640 by 480 pixel picture needs 307,200
bytes of memory, or 300 kilobytes.

On a system with absolutely no resident programs or device
drivers loaded... a rare thing... you can just load such a
picture into Desktop Paint 256 using nothing but DOS memory.
There will, however, be no memory left over to run the menus or
do anything with the drawing tools. A 640 by 400 line picture
fares a bit better... you can actually work with one to a limited
extent using nothing but DOS memory.

Desktop Paint is primarily intended for use as a full colour
paint program. It will edit pictures having fewer than 256
colours, but with a slight memory catch. Having fewer colours
does not allow a picture to take up any less memory under Desktop
Paint 256. Thus, a sixteen colour picture is still stored with
one byte per pixel, and a 16 colour picture will occupy exactly
the same amount of memory as a 256 colour picture of the same
dimensions. The same is true for a monochrome picture.

A monochrome picture of 576 by 720 pixels... the dimensions of a
MacPaint file... will occupy about 50 kilobytes under the
monochrome version of Desktop Paint and about 400 kilobytes under
Desktop Paint 256. As was mentioned above, Desktop Paint 256 will
handle monochrome pictures if you insist, but it's not the ideal
tool for it.


A WORD ABOUT COLOUR
___________________

A VGA card in one of its 256 colour modes can display 256 unique
colours drawn from a palette of a quarter of a million. This
presents a program like Desktop Paint 256 with a bit of a
problem. Assuming that there are 256 colours in the picture you
want Desktop Paint 256 to work with... that is, that all the
available screen colours are spoken for... Desktop Paint 256
would be left with nothing to draw its menus, icons and other
paraphernalia in.

Desktop Paint 256 gets around this problem by finding five
"system" colours in the palette of each picture it loads. The
ideal system colours are the ones it uses when there's no file in
memory, that is, white, black and three levels of grey. When a
picture has been loaded, it finds the colours in the picture's
256 colour palette which are as close as possible to its ideal
system colours and uses these. Thus, for example, "white" might
actually be bright green if bright green happens to be the
lightest colour in the picture you want to work with.

This could be a problem if you were to load in a picture of a
sand dune or a tar pit, for example, wherein all 256 colours were
nearly identical. In practice, this rarely happens.

Unlike some commercial paint programs, Desktop Paint 256 will not
arbitrarily remap a few colours in your picture to create
suitable colours for its menus. Nor will it assume that the
extreme ends of the palette are also the the extremes of the
palette's colours. You'll never wind up with black text on a
black screen unless all the colours in your picture's palette are
black.

Here's another word about colour. A VGA card only has six bit
colour registers. Colour image files define colours with eight
bit values. This means that, for example, a VGA card can only
display 64 unique levels of red, while an image file can specify
256 levels. When a VGA card gets hold of an image file, then,
each group of four consecutive eight bit levels of red would be
mapped to one six bit level for the VGA card.

This means that you can theoretically draw with more colour
resolution than your screen can show you.

This can be important in working with grey scale TIFF files. A
VGA card can only display 64 levels of grey, whereas a grey scale
TIFF file of the type Desktop Paint 256 can work with can hold
256 levels. You will find, for example, that a gradient which
runs from black to white will have noticeable bands on your
screen, but that the bands will not be particularly noticeable
when you print the file.

Here's yet another word about colour. Each pixel of an image is
actually a number corresponding to one of the 256 available
colours. If you define two different colours as being the same
shade of bright blue, they will look identical but they'll be
two different colours to Desktop Paint 256.

Finally, if you work with sixteen-colour pictures under Desktop
Paint 256 and subsequently view them on a sixteen-colour display,
you may find a marked difference between the colours you've
worked with under Desktop Paint 256 and those on your sixteen-
colour screen. Desktop Paint 256 allows you to control colour to
a greater resolution than a sixteen-colour display can handle.


A WORD ABOUT TIFF FILES
_______________________

The TIFF standard was originally devised jointly by Aldus and
Microsoft in order to infuriate all the programmers in the
world to such an extent that they'd take up stone carving or
Morris dancing, leaving Aldus and Microsoft with little
competition. While this strategy cannot be said to have been
wholly successful, TIFF files remain vexing little beasts none
the less.

There are nine million or so ways to create a TIFF file, with
more being devised every day. No two applications which generate
them do so in the same way. As such, few applications exist which
can claim to be able to successfully unpack all TIFF files.

Desktop Paint 256 is not one of these. It can only work with a
very small percentage of TIFF files. Specifically, it will import
TIFF files having one or eight bits per pixel, the latter in
either in full colour or as grey scale files. It will handle TIFF
files which have been packed using no compression or using run
length compression, but not ones which employ some of the more
exotic compression methods, such as Huffman encoding, CCITT FAX
compression, LZW compression and so on.

The principal use of the TIFF file handling of Desktop Paint 256
is to allow it to serve as a graphic front end for such programs
as Ventura Publisher, PageMaker and Corel Draw. The TIFF files it
creates are suitable for use in these applications. No promises
are extended for other applications which purport to read TIFF
files.

Likewise, if your scanner's TIFF files won't read into Desktop
Paint... or files from other sources which export in the TIFF
format... you've probably encountered some of the nasties.

You might want to get a copy of our Graphic Workshop package if
you'll be working with TIFF files. It can read a wider variety of
them, and it will help you analyze TIFF files to see how they're
structured.

You can have Desktop Paint 256 write TIFF files either in colour
or as grey scale files. Colour files will preserve colour
information in the same way the other colour formats Desktop
Paint 256 support do. Grey scale TIFF files are specifically
intended to be used by applications which import pictures for
printing as halftones on a black and white PostScript laser
printer.

If you import a colour GIF file into Desktop Paint 256, for
example, and save it as a TIFF file with the grey scale option
enabled, all the colours will be replaced with appropriate shades
of grey.

Grey scale files usually look a bit flat when they're printed.
For this reason, there's a second TIFF option which will allow
you to "expand" the TIFF grey scale to make it more contrasty when
you save a TIFF file to disk. You should enable TIFF grey scale
expansion if the TIFF files you're saving will be imported into
an application which will ultimately print them. You should
disable this option if you're saving grey scale TIFF files which
you will later load back into Desktop Paint 256 for further
modification.

Note that the setting of the TIFF grey scale option will be
ignored if Desktop Paint 256 will be writing colour TIFF files
rather than grey scale ones. It will also be ignored when you're
working with monochrome... one bit per pixel... TIFF files.

You can set up these two TIFF options through DTPCINSTL,
described above. You can override them with the appropriate
command line switches, as discussed later on, and with the
Override box in the File menu from within Desktop Paint 256.


WHAT ALL THE SCREEN BITS ARE CALLED
___________________________________

This is a twenty second overview of what all the screen objects
will be referred to as. You can probably skip most of this.

The white line at the top of the screen is the menu bar.

The box at the left is the toolbox.

The place where your picture appears is the work space.

The box at the bottom with all the coloured tiles in it is the
palette.

The box to the left of the palette is the colour selector. This
is the bit you probably shouldn't skip. The left side of the
palette selector is the current foreground colour. The right side
is the current background colour. The foreground colour is
manipulated with the left mouse button. The background colour is
manipulated with the right mouse button.


THE MENUS
_________

The easiest way to go through the functions of Desktop Paint 256
is to look at its menus and toolbox. Here's a quick overview of
the menus, starting from the left edge of the screen.

Note that many of the menu items have keyboard equivalents. This
is indicated by a diamond and a letter, the diamond representing
the Alt key. For example, if you wish to select the Open
function, you may do so by either selecting it from the file menu
or by holding down the Alt key and hitting O.

Some menu items may be printed in grey type, rather than in
black. These are disabled. Items are disabled because it's
inappropriate to use them at the moment. For example, you would
not be able to select the Print item until there was a picture in
Desktop Paint 256 to print.


The Desk Menu
-------------

    Clipboard:
This function lets you see the most recent fragment cut or copied
from a picture. The Clipboard is a holding area for bits of
images. In the Clipboard window, the current contents of the
Clipboard will be displayed padded out with black if they're too
small to fill the window or cropped if they're too big. This is
only how the image is displayed in the window, and will not
affect it when it's pasted into your picture.

You can import and export small image files into and out of the
Clipboard in the current file format, as set by the File Type
item of the File menu. The dimensions of imported files must be
fairly modest... certainly no larger than those of your current
drawing area. The Clipboard will complain if attempt to import a
picture which it considers to be too large.

You can change the file type to import pictures in a file type
other than that of the picture you're working on. For example, to
import a small PCX file into the Clipboard while you're working
on a larger TIFF file, load the TIFF file, select File Type from
the File menu and select PCX. Select Clipboard from the Desk menu
and click on Import. Select the PCX file you wish to import. Once
you've closed the Clipboard window, you can use the Paste item of
the Edit menu to paste the imported picture into your drawing.
We'll discuss cutting and pasting in greater detail in the Edit
menu section.

If you import a fragment into the clipboard which originally came
from a picture other than the one you're currently working on,
there will be a bit of a palette problem. Your main picture will
have a 256 colour palette and your imported fragment will have a
different 256 colour palette. As a VGA card can't deal with two
palettes at once, each colour in the imported picture will be
replaced with the colour which most closely matches it from the
palette of your main picture.

This colour "remapping" may or may not have a noticeable effect
on the colours of your imported fragments, depending upon how
much alike the colour palette of your main picture and fragments
imported into the clipboard are.

    Screen Save:
If you select Screen Save, a file dialog box will pop up allowing
you to capture the current screen into an image file of the
current type. The capture will not include the dialog box or the
mouse cursor.

You can also capture the screen to a file by hitting Alt 1. This
allows you to capture the screen when a menu is visible, a window
is open and so on.

    About:
The About box will tell you what version of Desktop Paint 256 you're
using, as well as how much memory you have free at the moment.
Note that is only conventional DOS memory... it does not include
any EMS or XMS you may have on hand. It also displays the driver
name.


File Menu
---------

    New:
The New function allows you to create a blank drawing of any
size... at least, of any size you have memory for. The smallest
dimension a drawing can have is thirty-two pixels on a size. The
largest is 32,767 pixels. Note that a drawing 32,767 pixels
square would require well over a thousand megabytes of EMS or XMS
to contain it. You cannot create a new drawing which occupies
more memory than you have.

    Open:
The Open function will load a drawing from your disk into Desktop
Paint. You must have the file type set appropriately before you
select Open. The same minimum and maximum file sizes apply to
Open as they do to New. You can't open a file if there's one
currently visible in Desktop Paint 256... you must close your
existing file first.

    Close:
The Close function disposes of an existing drawing and prepares
Desktop Paint 256 to have a different drawing opened or created.

    Save:
The Save function will save your current drawing back to the disk
under the current file name. If you have started your drawing
from scratch with New, you must first select Save As to assign it
a file name.

    Save As:
The Save As function allows you to save your drawing under a new
file name. The file type will be the current file type, as set by
the File Type function.

    Print:
The Print function will print your current drawing to a laser or
dot matrix printer. Desktop Paint 256 supports PostScript and
LaserJet compatible laser printers in four resolutions. Note that
even though your printer may have three hundred dot per inch
resolution, you can still print to it at a lower resolution.
Selecting, for example, one hundred dot per inch resolution will
cause the picture to be printed larger.

Pictures printed to PostScript printers will be output as screen
halftones. Other devices... LaserJets and dot matrix printers...
will print your pictures as dithers. Desktop Paint 256 does not
support colour printers as yet.

Desktop Paint 256 prints to a dot matrix printer through a special
driver resource called a PDRV, which lives in DTP.RES. There is a
PDRV installed in the distribution version of Desktop Paint 256 for
an Epson FX-80, which is emulated by most dot matrix printers.
This option will be visible as the ninth printer in the print
box list.

If you don't need dot matrix support you can remove the PDRV from
DTP.RES to save a bit of disk space, memory and to shorten the
time it takes Desktop Paint 256 to boot up. Managing resources is
discussed later in this file.

If there is no PDRV available, the ninth printer will be
unavailable.

You can select the number of copies to be printed. The number can
range from 1 through 99. Note that this value only affects output
to laser printers. Printing to an external printer driver will
only print one copy at a time no matter how the Copies value is
set.


    Overrides:
This item will allow you to fine tune some of the default values
for Desktop Paint. Anything you change in the Overrides box will
stay changed for the rest of your current session in Desktop
Paint 256.

The New values affect the default size for images created by the
New menu item. The smudge value affects the degree of fuzziness
caused by the Smudge command of the Edit menu, to be discussed
shortly. The posterize level setting determines how the posterize
function will work, to be discussed shortly. The TIFF options
have been discussed.


    Get Info:
This will allow you to look at any image file of the currently
selected file type and see how big it is, how much memory it will
require to edit, how many colours it has and so on.


    File Type:
The File Type function will allow you select the file format for
use in subsequent file operations. The current choices are
PCX, GIF, IFF/LBM and TIFF. Note that you can load a file from
one format, change the file type and then save it in another. The
current file type setting affects Save, Save As, Open, Get Info
and the import and export functions of the Clipboard.

    Quit:
The Quit function returns you to DOS.


Edit Menu
---------

    Copy:
The Copy function is only active when an area of your drawing has
been selected using the Select tool... the scissors. When
selected, the Copy function will copy the contents of the
selected area into the Clipboard.


    Cut:
The Cut function behaves like Copy except that it will fill the
selected area with white and unselect it.


    Paste:
The Paste tool is only active if there's something in the
Clipboard. It will paste the current contents of the Clipboard
into the upper left corner of the drawing window. It will be
selected, and you can move it to where you want it to be. If you
hold down the control key while pasting, the pasted fragment will
be transparent.


    Clear:
The Clear function behaves like the Cut function except that it
does not copy the selected area to the Clipboard. It just fills
it with white and unselects it.


    Invert:
The Invert function is only active when an area of your drawing
has been selected. It inverts all the pixels in the selected area
to their approximate negative colour values. Note that in
choosing a negative colour value, Desktop Paint must find the
ideal colour and then locate a palette colour which more or less
matches it. As such, inverting an area twice will return the area
to more or less normal colours, but you'll usually notice some
colour shift.


    Flip horizontal:
The Flip Horizontal function is only active when an area of your
drawing has been selected. It flips the selected area right to
left.


    Flip Vertical:
The Flip Vertical function is only active when an area of your
drawing has been selected. It flips the selected area top to
bottom.


    Rotate (90, 180 and 270):
These three functions are only active when an area of your
drawing has been selected. They rotate the selected area by the
specified amounts.


    Scaling
The Scaling function is only active when an area of your
drawing has been selected. It scales the selected portion of your
drawing to your choice of sizes... a dialog box will pop up
asking for a scaling factor. The scale factor can range from .1
(ten percent of your original) to 10 (one thousand percent of
your original) assuming that the scaled fragment will actually
fit in the drawing window. You can specify different horizontal
and vertical scaling factors by selecting the "Anamorphic" box.
If this box is not selected, clicking in the most recently
changed value will copy it to the other value.


    Stain:
The Stain function is only active when an area of your drawing
has been selected. It causes all the pixels in the selected area
which are of the foreground colour to be replaced by the
background colour.


    Smudge:
The Smudge function is only active when an area of your drawing
has been selected. It will blur the image within the selected
area. You can control the degree of blurring by adjusting the
Smudge value in the Overrides box, or permanently through
DTPCINST.EXE.


    Soften:
The soften function is only active when an area of your drawing
has been selected. It will soften the image within the selected
area. The softening is fairly subtle. It's also fairly processor
intensive, and softening areas of moderate size will take a
while. As such, a wait window will open while the soften function
is working to indicate how much longer the process will require.
Softening is very useful for reducing the effect of moire
patterns which occur when screened pictures are scanned.

    Posterize:
The posterize function is only active when an area of your drawing
has been selected. It will map all the colours in the selected
area to a fixed number of colour steps, as set by the posterize
level value. This can be set to a default value when you
configure Desktop Paint 256 and adjusted with the Overrides item
of the File menu.

    Sharpen:
The sharpen function is only active when an area of your drawing
has been selected. It will sharpen the image within the selected
area. Sharpening is also fairly processor intensive, and
sharpening areas of moderate size will take a while. As such, a
wait window will open while the sharpen function is working to
indicate how much longer the process will require.


Gadgets Menu
------------

    Gradient:
The Gradient function allows you set the characteristics of the
gradients which are drawn by the Gradient tool, to be described
shortly.

    Set Line:
The Set Line function selects the current drawing line width and
colour. The current choice for line width are one, two or three
pixels. You can also select no thickness, which is useful if you
want to draw a filled rectangle, ellipse or gradient with no line
around it.

    Set Fill:
The Set Fill function lets you decide whether rectangles and
ellipses will be filled with the foreground or background colour.

    Grid:
The Grid function allows you to turn the magnetic grid on and
off, and to set its spacing. When the grid is switched on, the
mouse will snap to the nearest grid point when you draw things,
allowing you to accurately position lines, rectangles, ellipses
and so on.

    Palette:
The Palette function will allow you to change the whole colour
palette of your picture, that is, to make all the colours more
red, or brighter, for example. You can change the colour values
by up to half their range in either direction.

This function is intended to allow you to fine tune the colour
balance of a picture. Note that if you really crank things up or
down, you can lighten or darken the palette so much as to make it
impossible to see the controls. In this case, hit Esc to return
things to normal.

The Reset button will restore the palette to its state before you
started playing with the sliders.

Note that once you click on Ok in the Palette box, you can't undo
the changes you've made to the palette.


Text Menu
---------

    Font Size:
The Font Size function selects the size in which the current font
will be drawn. It will also tell you what the current font is,
just in case you forget. When Desktop Paint 256 first boots, the
current font is the first one in the Font menu and the current
size is the smallest size that font is available in.

    Left, Centre and Right:
These functions set the direction that text will be drawn.


Font Menu
---------

The Font menu will only appear if DTP.RES is present and if there
are some fonts in it. Desktop Paint 256 comes with three fonts
initially, these being Swiss, Dutch and Courier. Swiss
corresponds to ITC Helvetica and Dutch corresponds to Times
Roman. Courier looks like typewriter type. Various sizes of Swiss
and Dutch are available.

Selecting a font from the Font menu will make it the current text
font when you next use the text tool. A check mark will appear
next to the name of the current font in the font menu.


THE TOOLBOX
___________

The toolbox will appear at the left side of your screen when you
have opened or created a drawing file. The currently active tool
will be inverted. You can select a new tool by clicking on it.

    Selector (the scissors):
The Selector tool allows you to select areas of your drawing.
Selected areas can be transformed using the tools in the Edit
menu.

You can move a selected area by placing the mouse cursor in it,
holding down the left button and dragging it to its new location.

If you hold down the left shift key while you select an area, the
original image below the selected area will be left behind, and a
copy made to appear in the selected box. If you do not, the image
below the selected area will be filled with white.

You can cause a selected area to become a permanent part of your
drawing by clicking outside it. The selection box will go away.
This is called "deselecting".

If you paste an image fragment into your drawing, it will appear
in the upper left corner of your drawing window and behave as if
it had been selected with the left shift key held down.

    Airbrush (ozone friendly spray paint):
The Airbrush tool will allow you to spray random areas of colour
pixels in your drawing window. The longer you leave the mouse in
one place and held down, the blacker the area will become. As
with all tools, selecting the airbrush tool and painting with the
left mouse button will paint in the foreground colour. The right
button will paint in the background colour.

    Text (the big T tool):
The Text tool will allow you to draw text in your picture using
the currently selected font, font size and direction. The text
will emanate from wherever you click in the drawing window. A
vertical text cursor will indicate where the next character will
appear.

If you hit Enter when you are typing text, the cursor will move
down a line.

You cannot draw text if part of the text would appear outside the
drawing window.

Text is always drawn in the foreground or background colour,
depending upon which mouse button you use.


    Line:
The Line tool allows you to draw lines. The thickness of the
lines is set by the Set Line function in the Gadgets menu. The
colour will be determined by the mouse button you use to draw
with. As there is no sense in drawing a line with no thickness,
the line thickness will default to a thin line if you have it set
to no thickness.

You can constrain lines to be perfectly horizontal, vertical or
diagonal by holding down the left shift, right shift or alt key
respectively.

    Eraser (the pencil end):
The Eraser tool allows you to erase areas of your drawing. Eased
areas will be filled with the current background colour. The left
mouse button will generate a small eraser. The right mouse button
will generate a bigger eraser.

    Rectangle:
    Filled rectangle:
The Rectangle tool draws rectangles... seems pretty obvious,
doesn't it... Rectangles will be drawn in the current line
thickness in the colour selected by the mouse button you choose.
They will be hollow if you select the hollow rectangle tool and
filled with the current fill colour... as set in the Set Fill
item of the Gadgets menu... if you select the filled rectangle
tool.

You can constrain rectangles to be perfect squares by holding
down the Alt key.


    Fill (paint roller):
The Fill tool performs a "flood" or "bucket" fill using the
current foreground or background colour based on the mouse button
you use to set it off.

The fill tool likes to fill closed areas. If the area you attempt
to fill has a hole in its periphery, the paint will leak out and
fill the area outside it, too. The Undo tool is very useful when
you're using the Fill tool.


    Ellipse:
    Filled ellipse:
The ellipse tool draws ellipses. In fact, due to a limitation in
the current ellipse algorithm, you'll see a rectangle as you draw
the ellipse and an ellipse only after you release the mouse
button. Ellipses will be drawn in the current line
thickness in the colour selected by the mouse button you choose.
They will be hollow if you select the hollow ellipse tool and
filled with the current fill colour... as set in the Set Fill
item of the Gadgets menu... if you select the filled ellipse
tool.

You can constrain ellipses to be perfect circles by holding
down the Alt key.


    Undo:
The Undo tool will undo the last thing you did and then select
whatever tool you were using before you selected undo. Changes to
your drawing cease to be undo-able after you save the drawing,
scroll the drawing or draw something else.

A note about undo: The undo works by copying the appropriate part
of the picture you're working on from its buffer onto the screen
when you click on the undo tool, thus wiping out the changes you
want to undo. Obviously, this will wipe out everything since the
last time the buffer was updated from the screen.

In a monochrome paint program, such as the monochrome version of
Desktop Paint, it's practical to update the buffer just prior to
each drawing operation. As such, you can undo single operations.

Because of the amount of data involved in a full colour picture,
this isn't practical under Desktop Paint 256. As such, the buffer
is updated when you click on a scroll bar, when you change tools
and when you save a picture to disk.

If you draw three rectangles in succession and then click on the
undo tool, all three rectangles will vanish. To make your current
drawing non-undoable, click on the a scroll bar or temporarily
change tools.


    Brush (the paintbrush):
The Brush tool allows you to draw free form lines in the line
colour corresponding to the mouse button you're using and in the
currently selected line width.


    Zoom (the magnifying glass):
The Zoom tool allows you to zoom in on a section of your drawing
and make pixel by pixel changes to it. When the zoom window is
open, clicking in the enlarged area with the left mouse button
will draw in the current foreground colour. The right button will
draw in the background colour. You can select new colours by
clicking in the palette.

You can also select colours from the zoom box image. If you hold
down the left shift key while the zoom box is open and click on
a pixel in the enlarged image fragment, the current foreground
colour will be set to the colour of that pixel. The same thing
goes for the right mouse button and the background colour.

The Zoom tool allows you to wash colours. If you hold down the
Alt key and draw in the enlarged image fragment, the pixel under
the mouse will change to a colour which is tinted with the
current foreground or background colour, depending upon which
mouse button you hold. This process is can be a bit
unpredictable, as the colour chosen for the wash must come from
the existing colour palette, wich may not have very good matches
for some intermediate colours. You'll probably want to experiment
with this a bit.

You can Undo zoomed changes if you don't like them after you've
closed the Zoom box.


    Gradient:
The Gradient tool draws rectangles which will be filled with a
graduated grey tone, the details of which are defined in the Set
Gradient function of the Gadgets menu. The area will be
surrounded by a line as defined in the Set Line function of the
Gadgets menu. You can have a no thickness line if you like.

Gradients are useful for giving areas a three dimensional
appearance.

Gradients run from the current foreground colour to the current
background colour. Using the Gradient box in the Gadgets menu,
you can decide whether gradients should run vertically or
horizontally.

The Gradients box also allows you to select how gradients will be
formed. Colour mapping creates a hypothetical gradient which
makes a smooth transition between the two extreme colours, and
then selects colours from the current palette which best match
the ones it has mathematically arrived at.

Dithering creates a gradient by dithering between the two extreme
colours.

In most cases, colour mapping will not work well in colour
pictures as there will not be a sufficient selection of colours
to create an attractive gradient. Colour mapping looks great in
grey scale pictures. If you're working with a colour image,
select the dithering option for gradients.


    Eyedropper tool:
The eyedropper tool allows you to change the curret foreground
and background drawing colours by picking colours from within
your picture. If you select the eyedropper tool and click in the
work space with the left mouse button, the foreground colour will
change to the colour of the pixel under the mouse cursor. If you
click with the right button, the background colour will change.

    Blank tool:
This tool doesn't do anything. It's a space filler because at the
moment there are an odd number of tools implemented in Desktop
Paint 256, and the toolbox looked funny with one icon missing.


USING THE PALETTE AND THE COLOUR SELECTOR
_________________________________________

All the available colours are displayed at the bottom of your
screen in the palette box. Clicking on one with the left mouse
button will make it the current foreground colour. Clicking on
one with the right mouse button will make it the current
background colour.

If you click in one of the colour tiles of the colour selector...
the box to the left of the palette... a window will appear to
allow you to change the percentages of red, green and blue light
which make up the colour in question.

As has been discussed, there are five colours which Desktop Paint
256 selects for use as "system" colours, colours which it uses to
draw its windows, buttons and so forth. You can edit these if you
happen to select one, but the colour adjustment window will warn
you that you're meddling with a system colour.

The Test button will tell you how many times a specific colour
has been used in your picture. It's not uncommon to find scanned
images with unused colours, usually at the ends of their
palettes. If you have to create a custom colour... to add some
text to a picture, for example... you should try to find an
otherwise unused colour.


COMMAND LINE SWITCHES
_____________________

You can use command line switches when you run Desktop Paint 256
to temporarily adjust the settings which DTPCINST configures.
Each command line switch is of the form /XXX, a slash and three
letters. Multiple switches should be separated by spaces.

These are the current command line switches.

/DOS - disable EMS or XMS
/EMS - enable EMS
/XMS - enable XMS
/PCX - default to PCX files
/GIF - default to GIF files
/IFF - default to IFF/LBM files
/TIF - default to TIFF files
/RES - disable loading DTP.RES
/TCL - Create colour TIFF files
/TCG - Create grey TIFF files
/TXP - Expand TIFF grey scale
/TXN - Do not expand TIFF grey scale


FONTS
-----

Assuming that you have fonts installed in DTP.RES, the Font menu
will appear in Desktop Paint 256 and you'll be able to type text into
your pictures. Desktop Paint 256 comes with a basic selection of
fonts, and you can add more to it.

Fonts are large, and a whole family of fonts can easily cause
DTP.RES to swell by a few hundred kilobytes.

There is no commercial source of proportional bitmapped fonts for
PC applications per se. Instead, Desktop Paint 256 allows you to
utilize fonts from other sources. Specifically, you can convert
bitmapped fonts from GEM applications such as Ventura Publisher,
from Microsoft Windows 3 FNT files and from Macintosh FONT and
NFNT resource files. Once converted, these fonts can be added to
Desktop Paint 256.

If you downloaded Desktop Paint 256 from a bulletin board, you'll
probably be able to find a wealth of suitable fonts there too.

There are three separate programs to do these conversions,
GEM2FONT, MAC2FONT and WIN2FONT respectively. There is also a
program called SEEFONT which will allow you to look at samples of
the fonts you've converted to see what they're like.

The basic Desktop Paint 256 package does not include these tools...
it's arguably big enough as it stands. Registered users can have
a disk with these programs on it as well as an assortment of
additional fonts ready to add to DTP.RES for $10.00 if it's
ordered when you register, or for $15.00 afterwards.

The font toolkit also includes the source code and instructions
to write your own assembly language dot matrix printer driver
PDRV resource, should you feel like doing so.


MANAGING RESOURCES
__________________

You do not have to understand one word of the next section to use
Desktop Paint 256. You can skip it with impunity if you like.

The DTP.RES file is a list of resources. Resources are unrelated
bits of data and code which Desktop Paint 256 might need. These could
have been kept as separate files, but keeping them all in DTP.RES
makes them easier to manage, requires less space on your hard
drive and allows Desktop Paint 256 to get at them more rapidly.

Desktop Paint 256 looks at DTP.RES when it first boots up... assuming
that it's there at all. If Desktop Paint 256 can't find DTP.RES, it
simply doesn't use any of the things it expects to find as
resources, such as fonts.

All of the resources which might be in DTP.RES are optional. If
you don't want to deal with resources or you like Desktop Paint 256
as it is, just skip this section.

These are the resource types which Desktop Paint 256 will recognize
in DTP.RES.

    FONT - screen fonts
    MENU - alternate menus
    PDRV - dot matrix printer driver
    CMAP - alternate default colour map (palette)
    VGAD - a screen driver stored in a resource

Some or all of these may be present in DTP.RES, depending on how
you want to configure Desktop Paint 256.


Using RMOVER
------------

In order to work with resources you'll need RMOVER.EXE, which is
included with the package. RMOVER allows you to add resource
files together, to extract resources from a file, to delete
resources from a file and to list all the resources in a file.

    Listing resources:
Let's begin with the simplest function of RMOVER, listing the
resources in a resource file. DTP.RES is a resource file. To see
what was in it, you would do this.

RMOVER DTP /L

You would see something like the following list for the DTP.RES
file which comes with the distribution version of Desktop Paint 256.

    Deleting resources:
This is how you would delete a resource from DTP.RES with RMOVER.
Let's delete the PDRV resource. This has resource number zero.

RMOVER DTP /D /TPDRV /N0

The /D switch tells RMOVER to delete a resource, /T switch tells
it the type of the resource to delete and the /N switch tells it
the number of the resource to delete.

    Extracting resources:
This is how you would extract a resource from DTP.RES, that is,
to copy it from DTP.RES to a separate resource file of its own.
Extracted resources live in resource files having one resource.
You could later add such a resource to another resource file. In
this example, we'll extract the PDRV resource. Note that this
will not delete it from DTP.RES.

RMOVER DTP /E /TPDRV /N0 /FEPSNFX80.RES

The /T and /N switches work as before. The /E switch tells RMOVER
to extract a resource. The /F switch tells it the name of the
file to put the extracted resource in. This file...
EPSNFX80.RES... will be deleted if it exists and a new one
created.

    Adding resources:
This is how you would add a resource to DTP.RES. In this example
we'll add COLOUR.CMP to DTP.RES. This is an alternate default
palette which will be used if you use the New function of the
File menu.

RMOVER DTP /A /FCOLOUR.CMP

The /A switch tells RMOVER to add a resource. Note that all the
resources in the file indicated by the /F switch will be added to
DTP.RES.

NOTE: RMOVER can quite easily delete resources you might want to
keep if you give it erroneous instructions. Keep a backup copy of
your resource files while you're working with it.


Common Resource Types
---------------------

Here's what each of these resources does and how to work with
them.

Make sure as you work with DTP.RES that you keep a copy of the
original DTP.RES file which comes with Desktop Paint 256 so you can
start over if you find you've deleted something you might want.

    The FONT Resources:
Each font which will be available in Desktop Paint 256 must have a
separate resource. Thus, if you have Dutch in seven sizes, there
will be seven FONT resources for Dutch. A complete discussion of
fonts is available in FONTS.DOC, which comes with the font
toolkit discussed above.

Note that Desktop Paint 256 can function without any fonts in
DTP.RES at all. If you have no need of the text capabilities in
Desktop Paint 256 and you want it to boot up more rapidly, remove
all the fonts from DTP.RES.


    The MENU Resources:
You can add MENU resources to DTP.RES to change the names of the
menu items in Desktop Paint 256. The AMERTEXT.RES file included with
Desktop Paint 256 is an example of such a menu. It replaces the Text
menu in Desktop Paint 256 with one in which the spelling of "Centre"
is American, that is, "Center". Add AMERTEXT.RES to DTP.RES if
you want to make this change.

The Desktop Paint 256 package does not come with a resource file
editor, which is what you would need to create further custom
menus. Registered users of the software can contact us for more
information about modifying resources like this if they wish.

    The CMAP Resource:
When you create a new picture with Desktop Paint 256, the default
palette has 256 shades of grey. However, if a different default
palette is stored in DTP.RES as a CMAP resource, it will be used
instead. One comes with Desktop Paint 256 in the file
COLOURS.CMP. If you get the font toolkit, you'll find a utility
called PCX2CMAP.EXE which will allow you to create your own CMAP
resources.

    The PDRV Resource:
If you want to be able to print to a dot matrix printer you'll
need a PRDV resource in your DTP.RES file. There's one in the
default DTP.RES to support the Epson FX-80, which is emulated by
most other dot matrix printers. If you want to drive a printer
which does not emulate the Epson FX-80, or you wish to use a
higher resolution mode of a more sophisticated printer, you must
create a new PDRV resource for your printer, delete the existing
PRDV resource from DTP.RES and put your PRVR in its place.

A discussion of printer drivers and the creation thereof can be
found in the Desktop Paint 256 font toolkit, described earlier.

    The VGAD Resource:
Rather than specify a screen driver in DTPCINST, you can add it
as a resource to DTP.RES, which will make Desktop Paint 256 boot
up a little quicker and leave you with one fewer file to keep
track of. In order to convert a DRV file into a resource, you'll
need BIN2RES.EXE, which is provided with the font toolkit.

ROLL YOUR OWN
_____________

This is yet another book plug. If you're interested in writing
programs which use graphics, you'll find everything you need to
know in "Bitmapped Graphics", also by Steve Rimmer. It's
published by TAB books, (TAB book 3558). It features code to pack
and unpack MacPaint, IMG, PCX, GIF and TIFF files, as well as
chapters on screen drivers, dithering and printing.

If you would like to write programs with a graphical user
interface, you will find the complete user interface code for a
monochrome graphical user interface in The PC GUI Book by Steve
Rimmer, published by TAB Windcrest (TAB book 3875). It will be
available toward the end of 1991.

If you can't find these books locally, you can mail or phone
order them from the following bookstore:

Christies of Cookstown, P.O. Box 392, Cookstown, Ontario, Canada,

throbbing of your heartbeat. Just thought you'd want to know
that.
