!Reso-Aid
v 1.01 (14-Dec-1994)
This program is Shareware.
This means that you can copy this program to anyone you like, but if you
find the program useful, you should register, as explained below. This
entitles you to the latest version of this program, and of all my other
applications.
If you do copy the program it should be in its original format, with ALL of
the accompanying files. That is : !Boot
!Help
!Run
!RunImage
!Sprites
!Sprites22

Purpose
-------
A utility to provide varying utilities with differing screen resolutions.
To use
------
Double click on the icon in the filer window to load the program. This
will install an icon on the icon bar.
Click menu (the middle mouse button) on the icon on the icon bar to open
the program menu. This menu will have five options : Info, Save, Mouse setup,
Backdrop, and Quit. Moving the pointer across the Info option will allow you
to see the normal program information. Selecting Quit will quit the program
in the normal fashion. The save option allows for the data to be saved to
disk. The other two options allow control of how the program runs. Clicking
adjust (the right mouse button) on each option will toggle a tick beside it.
If the tick is shown, it means that that function is operative. If the tick
is absent, that function is inoperative, and the normal RISC-OS operation
applies. Clicking select (the left mouse button) on each option will open a
window offering control of its action.
To load a previously saved data file, double click on its icon in the
filer window, or drag the icon from the filer window onto the icon bar. This
will update the options in memory, and change the mouse step and backdrop if
the relevant options are set.
Save
----
Moving the pointer across this option will display a normal save box. From
here the data file can be saved to disk in the normal RISC-OS fashion. The
data file stores whether the mouse speed and backdrop options are on or not;
the mouse speed settings (x=y, x mult, y mult) and the backdrop settings.
NB. If the file is saved inside the !Reso-Aid application as Default, the
file will be loaded every time the application is started, unless the
application was initialised by double-clicking on a file in a filer window,
in which case the file that was double-clicked has priority.
Mouse speed
-----------
If this operation is on, every time the mode is changed, the mouse speed
adjusts slightly to compensate for the different screen resolution. The
higher the resolution, the higher the mouse speed. Thus to move the mouse
pointer from one edge of the screen to the other will always require
approximately the same physical movement of the mouse.
The control window for this option has three variables :
x speed = y speed
x multiplier
y multiplier
If the 'x speed = y speed' flag is set, any change made to the x or y
multipliers will also alter the other. If the flag is not set, different
multipliers are allowed for x and y. Also, if the flag is off, the
calculation made by the program is slightly different, to allow for the
different x and y resolutions.
To change the multiplier, click on either the up or down arrow to the
right of the number. A sensible number is 2 or 3.
To update the options, click on the OK icon.
Backdrop
--------
This function is only available to users of RISC OS 3.10 and greater.
If this operation is on, every time the mode is changed, a different
backdrop is chosen to correspond to the new resolution and colour choice.
The control window allows five states plus an 'otherwise' state to be
defined. The state needs to be :
x resolution y resolution colours Backdrop file
The x and y resolution icons are writable : type into these the
resolutions that the state should respond to. Risc PC owners can copy these
from the Display Manager resolution menu. Alternatively, and the only option
for users of an earlier version of RiscOS, click menu over the definition to
be changed. This will open a menu offering some predefined modes : 12, 15,
and a writable area, where a mode number can be entered. The program will
then read the mode data for the given mode and enter it into the relevant
areas. An error will be reported if the mode given is not defined.
Clicking select on the colour column will open a window allowing control
of what number of colours the definition should respond to. The available
options are : black/white (eg mode 0),
4 greys (eg mode 1),
16 greys (RiscPC only),
16 colours (eg mode 12),
256 greys (RiscPC only),
256 colours (eg mode 15)
32 thousand (RiscPC only)
16 million (RiscPC only)
The file column is also writable. In this icon, the filename of the
picture should be typed. NB. It is possible to specify how the backdrop
should be displayed (centred, tiled, scaled). The column actually represents
the string to be passed to the *BackDrop command. Therefore, include in the
column a string to keep the PinBoard module happy. Do *Help BackDrop for a
syntax of the string. Some example column strings are
-Centre <Wimp$ScrapDir>.Pic
-Tile adfs::HardDisc4.$.!Boot.Resources.Configure.Textures.T7
-Remove
When the mode is changed, the program will scan through the defined
states, and if it finds a definition with an EXACT match for x resolution, y
resolution, and which includes the correct number of colours, the backdrop
defined will be used. Otherwise, the 'otherwise' picture will be used.
NB. If the backdrop column is blank, the definition is ignored.
Finally, the program counts its errors and their time intervals. If it has
to report five errors, each one being within two seconds of the previous one,
then the program will kill itself. This solves (hopefully!) the problems of
an unbreakable error loop.

Please report any bugs found and any possible improvements you can think of
to me at the address shown below.
Registering
-----------
To register, send £5 to me, at the address shown below, stating what version
of which of my programs you have. You can enclose your own disk for the
programs, and if you do so you can deduct 50p from the price. Registering
entitles you to upgrade to later versions of the same programs and to get new
programs for the price of £1. Any additional contributions from overseas
towards postage would be greatly appreciated.
