G.I.P SHAREWARE - The Greyscale Image Processor
------------------------------------------------
Introduction
------------
This is version 1.0 of GIP SHAREWARE, a new image processor which is
available for the Atari ST/STE/Falcon030 computers.
This program is SHAREWARE. You may distribute it freely to anybody
you like, but if you use it ( and like it ) you should register.
To register you should send a cheque or postal order for 15 pounds
to the following address :-
Mr Stephen Found,
14 Bybrook Court,
Kennington,
Ashford,
Kent.
ENGLAND.
TN24 9JX
I am currently working on version 1.1 of GIP which will feature
more filters and processes but, due to the extra work involved will have
a 20 pounds registration fee. Registered users however will recieve a
FREE upgrade to ANY future releases of G.I.P SHAREWARE.
The author accepts NO responsibility whatsoever for any loss or damage
to data caused by this program. You use it at your own risk.
I have, however, tested the program on the STFM,STE and Falcon and
nothing has been lost or damaged to date ( Although many images have been
enhanced !!! )
I would also like to hear from you...
What are you using GIP to do ?
What hardware are you using ?
What would you like to see in future versions of GIP ?
How could the current version be improved ?
Send me a letter with your registration fee....
Documentation
-------------
There is very little user documentation provided as GIP has a cross
referenced help system built in. The help system is activated by selecting
'Help' from the 'File' menu, or by pressing the help key.
The help system covers every aspect of GIP. When a help screen is
displayed, certain key words will be highlighted. Clicking on these with
the mouse will take you to the help screen for that section. If you click
on 'previous' at the bottom of the help page, you will return to the
prviously displayed screen, clicking on 'Exit' will leave the help system.
Image Formats
-------------
GIP will load images from the following formats :-
TIFF Version 5.0 (.TIF)
Compuserve GIF (.GIF)
PC Paintbrush (.PCX)
Degas (.PI1) (.PI2) (.PI3)
Degas Elite (.PC1) (.PC2) (.PC3)
Monochrome IMG (.IMG)
Hyperpaint IMG (.IMG)
AIM Greyscale (.IM)
AIM Colour (.COL)
There is no restriction on image size, except the amount of memory
you have. When loaded, every image is converted into a 256 level greyscale
image. The image is stored as 1 byte per pixel, so a 320x200 image will
take 64000 bytes internally. The image must also be converted into the
Atari display format so that it can be displayed on the screen.
Our 320x200 image ( displayed in 16 colour mode ) would now take
64000 bytes for the image and 32000 bytes for the display totalling
96000 bytes ( nearly 96K ).
You may have up to 4 images loaded simultaneously in GIP. On a 520 ST
however this may well not be possible due to lack of memory.
TIFF input includes Classes B,G and P.
Class B - Bilevel images are usually output by Monochrome scanners
G.I.P will import uncompressed and 'Packbits' compressed
images.
Class G - Greyscale images are usually output by greyscale scanners
G.I.P will import uncompressed and 'LZW' compressed images
Class P - Palette colour images are usually output by paint packages
G.I.P will import uncompressed and 'LZW' compressed images
Class R - RGB (True) colour images are NOT currently supported by G.I.P
Image Output
------------
After processing your image you will want to save it. GIP will output
in IMG and TIFF formats. TIFF images can be uncompressed or LZW compressed.
Note however that some programs ( GEM View included ) do not seem to
recognise LZW compressed images, others ( such as TruePaint from Hisoft )
load them without problem.
As far as that old dinosaur the PC is concerned, I have only found one
package ( Coral Photopaint ) that loads compressed TIFF without fuss.
Many PC programs only load Intel format TIFF !!! ( But these are mostly PD
programs ).
G.I.P. outputs Motorola format TIFF images which load perfectly well
on both the Macintosh and Amiga, and will import Intel format TIFF without
fuss.
WARNING
-------
Some scanners, which output in TIFF format do not adhere to the TIFF
specification and 'miss' some required TIFF directory blocks. GIP WILL
NOT LOAD THESE, it will however inform you of the missing blocks.
You can usually load these images into programs such as GEM View or
TruePaint which 'guess' at what the missing blocks should be. If they
are then re-saved, GIP should then load them.
Printing
--------
G.I.P has 3 built in output formats, Hewlett Packard Laserjet,
Deskjet and Encapsulated postscript. Output may be directed through
the serial or parallel ports, or can be output to a file for later
printing.
Dot Matrix and Inkjet printers are not currently supported, as I
do not have much, or in most cases ANY, information about outputing
to them. If you require ( and you most probably do ! ) more printer
support, then I will see about including more printers in a future
version of G.I.P.
------------------------------
Support for the Atari Falcon
----------------------------
G.I.P executes perfectly on the Falcon030. All resolutions and
colour modes are supported. Multitos is also supported and an example
GEM.INF file can be found in the Multitos folder. All that is required
is that the GIP environment variable is set. When GIP detects this
variable, the percentage bar is disabled. ( The bar is 'annoying' when
Multitos is active ).
Well, I hope you enjoy using GIP and I hope you register your copy.
It is important to keep the Atari shareware market thriving as interest
in this BRILLIANT machine is starting to wane !!!
