Detailed Description

A pixmap class for xserver-side images.

Inherits line-drawing from its Drawable base class.

Member Function Documentation

Blits to a window.

Uses the display's default graphics context.

Definition at line 75 of file gxpixmap.cpp.

void GX::Pixmap::readImage ( unique_ptr< Image > & image ) const

Reads the image from the xserver.

(This is not in the base class because reading window images is less reliable wrt. occlusion etc.)
