Subject: ALLEGRO: Fast Palette Changing
Reply-To: djgpp AT delorie DOT com

I must switch between palette tables quite fast: i must draw 8bpp
RLE_SPRITE on a truecolor screen, and each sprite has different palette.

I messed around with Allegro SRC but I found set_pallete() quite
confusing.
Passing entire arrays (the PALLETE type) by value as function parameters
is not slow/unefficent? or are they automatically passed by reference?
There is a way to simply redirect a pointer to a PALLETE table, thus
changing palette with only an assignement "="?
This will let me use blender maps/funx for transparency?
How can I learn to use them (about this topic  ALLEGRO.TXT is not very
clear for a newbie)

Thanx.
