SizeofGraphic
size_t SizeofGraphic(lcd_surface_t *surface)
Calculate the total on-memory size of a surface (including descriptor).
_BitBlt
void _BitBlt(lcd_surface_t *dst, short xdstoffset, short ydstoffset, short xsize, short ysize, lcd_surface_t *src, int xsrcoffset, int ysrcoffset, unsigned short flags)
Perform blit operation from src surface to dst surface.
ImageData
void * ImageData(lcd_surface_t *surface)
Get the palette and bitmap buffer for an all-in-one surface.
GetImageSizeExt
size_t GetImageSizeExt(short width, short height, short depth)
