!AMFExpose  1.00 (23-Jun-92)
============================
Sprite Exposure
===============
AMFExpose is designed to alter the constituents of 256 colour sprites.When
loaded,it will allow the red,green and blue components of such a sprite to
be manipulated so as to create certain effects.For example,AMFExpose can be
used to turn a full colour sprite into a greyscale sprite,by using the
equation (r+g+b)/3 for each of the three colours.

Use
===
Once loaded,drag a 256 colour sprite file onto the AMFExpose icon.Two
windows will appear,one containing the sprite to be altered,and one named
AMFExpose.It is the AMFExpose window that the three formulas are entered in.
Each of the three colours is an 8 bit value from 0 to 255.Any mathematical
operation that can be achieved in BASIC can be entered into the formulae
boxes.Thus,let us consider the above example,namely converting a colour
sprite into a greyscale one.This can be achieved by entering (r+g+b)/3 into
the three formulae boxes.The effect of this is as follows.For each of the
256 colours,the red,green and the blue component are added together,to give
a total out of 768.This total is then divided by 3,to give a total out of
256,and used to provide all three components of the new colour,giving an
effective greyscale.Click on OK to start the process.The new sprite will be
shown in the sprite window.

By pressing menu on the sprite window,you can save the resulting sprite,or
you can zoom in on it in the usual manner.By pressing menu on the AMFExpose
window,you can save the three formulae as a script file,basically a text
file containing their definitions.This may be reloaded by dragging it over
the AMFExpose window.The Reload option will allow the original sprite file
to be reloaded,whereas View will open the sprite window,if it has been
closed.

AMFExpose will display sprites in all modes,although,quite naturally,it is
wiser to display a 256 colour sprite in a 256 colour mode,if possible.

AMFExpose cannot alter sprites with less than 256 colours,although even if
this were possible,the quality of conversion would be poor,by definition,due
to the limited number of colours.

Uses
====
1) Sprite darkening/lightening : Set all three equations to be multiplied or
   divided by the same number (for example,the red equation should be r*1.2
   to make the red component 1.2 times brighter)

2) Colour removing : Set that colour's equation to 0 to totally remove it.

3) Colour saturation : Set that colour's equation to 255.

4) Greyscale conversion : Set all three equations to (r+g+b)/3 (above).

5) Special effects : For example,set the red to green,and vice versa.Enter g
   in the red box,and r in the green box.

It should be realised that operations such as AND,OR,EOR,etc may be used in
AMFExpose.This allows for a far wider range of possibilities than that which
I can ever hope to list here.
