.SH NAME
draw_trans_rle_sprite \- Draws a translucent RLE sprite. Allegro game programming library.\&
.SH SYNOPSIS
.B #include <allegro.h>

.sp
.B void draw_trans_rle_sprite(BITMAP *bmp, const RLE_SPRITE *sprite,
.B int x, int y);
.SH 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:

.nf
   /* 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);
