Chapter 5 - Bitmap Shapes / Applying Functions Described Elsewhere to Bitmap Shapes

Ink-Related Functions Applicable to Bitmap Shapes

Since bitmap shapes contain their own color information in their geometries, QuickDraw GX does not use the color property of the ink object when drawing a bitmap. However, QuickDraw GX does consider the transfer mode of the ink object and applies it to each pixel when drawing a bitmap. You can use the GXSetShapeTransfer function, which is described in the chapter "Ink Objects" in Inside Macintosh: QuickDraw GX Objects, to assign a transfer mode to a bitmap shape.

You may also use the GXSetShapeColor function to set the color property of a bitmap's ink object and use the GXGetShapeColor function to examine this property. However, QuickDraw GX ignores this property when drawing a bitmap.
