Detailed Description

Pixmaps are offscreen drawables. They can be drawn upon with the standard drawing primitives, then copied to another drawable (such as a GdkWindow) with gdkPixmapDraw(). The depth of a pixmap is the number of bits per pixels. Bitmaps are simply pixmaps with a depth of 1. (That is, they are monochrome bitmaps - each pixel can be either on or off).

Convenient Construction

gdkPixmap is the result of collapsing the constructors of GdkPixmap (gdkPixmapNew, gdkBitmapCreateFromData, gdkPixmapCreateFromData, gdkPixmapCreateFromXpm, gdkPixmapColormapCreateFromXpm, gdkPixmapCreateFromXpmD, gdkPixmapColormapCreateFromXpmD, NULL, NULL) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.
