draw_trans_rle_sprite
Draws a translucent RLE sprite.
Description
Translucent version of draw_rle_sprite(). See the description of
draw_trans_sprite(). This must only be used after you have set up the
color mapping table (for 256-color modes) or blender functions (for
truecolor modes). The bitmap and sprite must normally be in the same
color depth, but as a special case you can draw 32-bit RGBA format
sprites onto any hicolor or truecolor bitmap, as long as you call
set_alpha_blender() first. Example:
/* Some one time initialisation code. */
COLOR_MAP global_trans_table;
create_trans_table(&global_trans_table, my_palette,
128, 128, 128, NULL);
...
if (get_color_depth() == 8)
color_map = &global_trans_table;
else
set_trans_blender(128, 128, 128, 128);
draw_trans_rle_sprite(buffer, rle_ghost_sprite, x, y);
