For the 1024x768 VGA tile driver:
|
|
2 longs are required for each text foreground/background color combo, arranged as:
|
|
$ff_bb_ff_bb
|
|
$ff_ff_bb_bb
|
|
where 'ff' is the foreground color and 'bb' is the background color
|
|
2 longs needed because characters are in an interleaved pair
|
|
The first long is the color for the first character in a pair, the second long is for the second character in a pair.
|
|
Demo routine "print()" only allows for 8 fore/back combinations (using longs 0 to 15)
|
|
|
|
1 long required for box colors, arranged as:
|
|
$tl_br_fi_bb
|
|
where 'tl' is top-left edge, 'br' is bottom-right edge, 'fi' is focus indicators, and 'bb' is background color
|
|
The demo "box()" procedure hardwired to add 16 to input color number to pick box color and adds 5 to input
|
|
color number to pick text color for box...
|
|
So, "box(left,top,clr,str)" uses color number 16+clr for box colors and 5+clr for text color. You probably want
|
|
the 'bb' background colors of these two to match! Note that this limits you to 4 box colors.
|
|
|
|
1 long used for graphics colors, arranged as
|
|
$00_11_22_33
|
|
where 00,11,22,33 are the selectable graphics colors 0,1,2,3
|
|
Demo hardwired to use the 21st long (last one) for the graphics colors
|
|
|
|
The Propeller's "tile driver" video uses 32-bit (long) values to define a four color palette
|
|
The "color_ptr" parameter, given to the tile driver, specifies the location of the data block of up to 64 different
|
|
long palette values
|
|
Each long palette represents 4 different colors, one byte each. Each color byte uses 2 bits for each primary colors,
|
|
RGB, arranged as RGBx. The "x" represents the two least significant bits, which are ignored.
|
|
Parallax gives this example of a 32-bit long palette, represented as a 16-digit quaternary (2-bit) number:
|
|
%%3330_0110_0020_3300 or $FC1408F0
|
|
The first byte, %%3330 (binary %11111100), is the color white
|
|
The second byte, %%0110, is the color dark cyan
