KB10746 - Georeferenced image layer matches up differently by a fraction of a pixel.

TatukGIS software interprets the location of the x,y coordinates for each pixel to be at the center of the pixel. Some software products interpret the location of the x,y coordinates to be at another place on the pixel, typically at one of the pixel corners. This can explain a slight (fraction of one pixel) shift in raster layer presentation between different GIS software products.
