title: GeoTIFF issue with opening in PIL
body: <p>Everytime I open an GeoTIFF image of a orthophoto in python (tried PIL, matplotlib, scipy, openCV) the image screws up. Some corners are beeing cropped , however the image remains its original shape. If I manually convert the tif to for instance a png in Photoshop and load it, it does work correctly. So it seems like PIL has some trouble handling tif files with objects that not fill the entire canvas. Does anyone have a solution for this problem?</p>
