AGA Utilities DocFile
=====================
The utils covered in this docfile are:
Iff-binary
Spriteconverter
ColourConverter
Iff-Binary
~~~~~~~~~~
This program will convert any IFF picture into a binary format
that you can use in your programs. This is a very simple utility to
use and doesn't really need much explaining. After loading Iff-binary
the different options available are listed, these let you select what
data to save with your file and how to save it.
The options are as follows :-
(A) T - 12 bit colours values. This when saving the colours stores
them in the old 12 bit word value format, by not selecting
this they are saved as two banks of 12 bit values for AGA
machines. ie. Changing a 128 colour screen to binary would
add a 128 words of the upper 4 bits of each RGB first then
a second set of 128 words of the lower 4 bits.
Colour value $f4e28c would be $fe8 and $42c.
(B) C - Cancel saving colours. Speaks for itself.
(C) S - Sequential data. This lets you choose from an interleaved
binary file or sequential.
(D) H - If the picture is HAM8 then this must be selected so the
right colours are saved.
To convert your file just follow the prompts to enter your
filename, options and then the new filename.
SpriteConverter
~~~~~~~~~~~~~~~
This utility will convert a 16 colour binary data file into two
64 pixel wide format files to be included in the example file on
this disc.
The process is simple :-
1. Draw your 16 colour image in say Dpaint.
2. Save it as a brush with a width of 64 pixels.
3. Run it through Iff-Binary and select C in the options to cancel
colour saving.
4. Now run this program and two files will be produced to load into
the program included.
Example - Spriteconvert df0:Mypicture.binary ram:Spritedata
The program will add an extension of .SP1 and .SP2 to the output
file.
ColourConverter
~~~~~~~~~~~~~~~
This program will change the header file on an image saved with
Iff-binary from two banks of word data into byte values for each
RGB component for use with the AGA fade routine.
The process is simple :-
1. Iff-binary your 128 colour image with no options ( just press
return ).
2. Now run this program and it will give you the required file.
Example - Colourconvert df0:Mypicture.binary ram:Mycolours 128
The value 128 must be added so that the utility knows how many
colours to convert.
