Detailed Description

An openGL/GLUT/GLOW window class that extends GlowWindow.

Added functionality allows images (Image/ImageRGB/ImageGrey) to be piped into the window and the display automatically refreshed with these images. Public mouse handler and graphics handler callback function pointers (and default functions) are included to add user functionality without inheritance.

(i.e cause program to hang) Definition at line 132 of file ImageWindow.cpp. References grab_grey(), grab_rgb(), graphics_callback, height, and width.
