|
Pixmaps are offscreen drawables. They can be drawn upon with the
|
|
|
|
standard drawing primitives, then copied to another drawable (such as
|
|
|
|
a #GdkWindow) with gdk_pixmap_draw(). 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).

An opaque structure representing an offscreen drawable.
|

Pointers to structures of type #GdkPixmap, #GdkBitmap,

and #GdkWindow, can often be used interchangeably.

The type #GdkDrawable refers generically to any of
|
|
|
|
these types.
