Detailed Description

Allows the display of openCV's IplImage images

This class is meant as a (step towards a) FLTK replacement for openCV's cvNamedWindow. It supports the display of 3 channel (RGB or BGR) images, as well as 1 channel (grayscale) images. It also allows the user to select a region of an image by dragging a rectangle.

Bug:

Region selection doesn't seem to work right when the image is not constantly refreshed
