GSDrawBitmapAtCP()

#define GSDrawBitmapAtCP(bsize_w) \
        GR_DRAW_BITMAP_CP, GOC_WORD(bsize_w)

Include: gstring.h

GSDrawBitmapOptr()

#define GSDrawBitmapOptr(x_w,y_w,o_ptr) \
        GR_DRAW_BITMAP_OPTR,GOC_SW(x_w), \

This GString creation macro draws a complex bitmap. It takes four arguments: the x and y coordinates at which to draw the bitmap, the size of one slice of the bitmap's mask and color data, and the total size of the bitmap's data. This macro should be followed by the bitmap's data: a CBitmap structure followed by the mask, color, and any other associated data.

Include: gstring.h
