While importing and manipulating some 2-D detector images from a Bruker system and saved using the python Pillow (PIL) library, I ran into some issues with the GSAS-II failing to read the TIF files. The problem seemed to be that there was no ’shape’ attribute
in the TIF file, but there was a ’size’. Adding the try/except blocks listed below resolved the issue. <br class="">

<div class="">One other note, the TIF reader seems to expect/want the integer based 8 bit files [0 to 255]. Outputting the TIF as a float worked ok on import, but the max/min intensity sliders didn’t permit decimal values. The float data seemed to be 32 bit,
so that may be relevant for additional users. Unfortunately the float TIF format requires values between 1 and 0, so it would be handy to have a way to input the counts to float scale.</div>
