Marios Patsias <m DOT patsias AT cytanet DOT com DOT cy> was overheard mumbling incoherently about HELP with Allegro (draw_sprite function): >I use the Allegro draw_sprite() function for displaying bitmaps, but >the bitmap isn't masked as it should be (according to the documentation), >and the blank pixel of it owerwrite the background. >Is there anything that I should know before using this function. >Note: The bitmap is a memory bitmap defined in a grabber .DAT file. Are you sure that the areas that should be transparent are color 0 (palette index 0, not necessarily black)? Many graphics programs don't give you complete control over the palette order. __ __ /> /_ /| / /\ /| /> /| / /_ / / /> /_ / |/ /_/ /-| / \ / |/ /_ /_ /_ http://users.vnet.net/bdarnell bdarnell AT vnet DOT net
