Parameters

x,y	Specify the window coordinates of the first pixel that is read from the drawable texture. This location is the lower left corner of a rectangular block of pixels.
width,height	Specify the dimensions of the pixel rectangle. width and height of one correspond to a single pixel.
flipImage	Specifies if needs to flip the image.
callback	Specifies a call back function to deal with the image.
