#include <tk.h> Tk_ImageChanged(imageMaster, x, y, width, height, imageWidth, imageHeight)
An image manager should call Tk_ImageChanged during its createProc to specify the image's initial size and to force redisplay if there are existing instances for the image. If any of the pixel values in the image should change later on, Tk_ImageChanged should be called again with x, y, width, and height values that cover all the pixels that changed. If the size of the image should change, then Tk_ImageChanged must be called to indicate the new size, even if no pixels need to be redisplayed.
