Re: [AD] DirectDraw - create_sub_bitmap() or save_bitmap() faulty ?

Just in case you others had the same problem to decipher the code...
Here's a slightly modified version...

#include<allegro.h>

int main(){
    int i;
    PALETTE p;
    BITMAP *B;
    allegro_init();
    install_keyboard();
    set_color_depth(8);
    set_gfx_mode(GFX_AUTODETECT_FULLSCREEN,320,240,0,0);
    for (i=120;i>0;i-=12) {
        circlefill(screen,160,120,i,i);
    }
    textout_ex(screen,font,allegro_id,0,0,13,-1);
    textprintf_ex(screen,font,0,60,32,-1,"%s/%dx%d/%d.%d",
                  gfx_driver->desc,
                  gfx_driver->w,
                  gfx_driver->h,
                  os_version,
                  os_revision);
    B = create_sub_bitmap(screen,0,0,SCREEN_W,SCREEN_H);
    textprintf_ex(B,font,0,80,48,0,"%dx%d%d",
                  B->w,B->h,B->vtable->color_depth);
    readkey(); 
    get_palette(p); 
    save_bitmap("test.pcx",B,p);
    destroy_bitmap(B);
} END_OF_MAIN();

While i'm not sure what the point of the code is, and what it has to 
do with directx9... at least it should be readable...

Maybe j13 could comment on the code?
