Drawing Pictures

QuickDraw GX provides two methods of drawing a picture:

• You can create a picture shape (by calling the GXNewPicture function, by copying an existing picture shape, and so on) and use the GXDrawShape function to draw the picture.
• You can create an array of shape references, and arrays of references to overriding styles, inks, and transforms, and use the GXDrawPicture function to draw the corresponding picture.

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

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