Detailed Description

Paint engine to be used in QGLWigets for a high performance image visualization.

The GLPaintEngine provides a QPainter like interface for drawing 2D-OpenGL primitives directly into a OpenGL graphics context. It provides the following functionalities:

line and fill color state machniene
antialized Font rendering with implicit scaling if desired
drawing primitives using pixel coordinates (lines, points, rects, ellipese)
drawing QImages and ICL-img images directly without buffering, flipping or converting image data in software.
brightness / (contrast / intestity) adjustment (in hardware)
