Detailed Description

Class for openGL-based image visualization components.

The ICLWidget class provide ICL's fundamental abilities for real-time image visualization. It always comes up with a set of special buttons, that are used to affect the image display in real-time. The left-most button shows an extra menu, which provides a larger set of additional options. The widget can be embedded to external Qt-based GUI-applications. However, we recomment to use ICL's GUI-Creation-Framework rather than using the ICLWidget class directly

Performance

Internally, the icl::qt:GLImg is used for OpenGL-texture-based image rendering. This allows image hardware-scaling -zooming, -intensity and -contrast-adaption.
