Drawing Bitmaps

QuickDraw GX provides two methods of drawing a bitmap:

• You can create a bitmap shape (by calling the GXNewBitmap function, by copying an existing bitmap shape, and so on) and use the GXDrawShape function to draw the bitmap.
• You can create a gxBitmap structure and use the GXDrawBitmap function to draw the bitmap.

In general, you should use the GXDrawShape function to draw any QuickDraw GX graphic, including bitmap shapes. In fact, the GXDrawBitmap function creates a temporary bitmap shape, uses the GXDrawShape function to draw it, and then disposes of it. The GXDrawShape function is described in the chapter "Shape Objects" in Inside Macintosh: QuickDraw GX Objects.

You would typically use the GXDrawBitmap function only in simple situations--for example, if you knew you wanted to draw a particular bitmap only once.
