Image processing is done using WinView32, a commercial product which must be purchased, and is fairly expensive. By default, at the beamline, images are saved in a proprietary format with the .SPE extension. These 16 bit images can be converted to 16 or 8 bit TIFF using WinView32 at the beamline. If you forget to convert them there, you can use the free IDL program here, called princeton_to_tiff_multi.sav. (Windows won't let you directly link to a file with a .sav extension, so I have called it princeton_to_tiff_multi.txt; when you connect to it, select "save as", and change the extension to .sav before you download it). To run it, you need to get the free IDL Virtual Machine. After you install the IDL Virtual Machine, simply double-click on the SAV file. It will open a navigation window with which you can browse to the location of your data (only .SPE files will show up). Select any or all of the files, and then go. In the conversion process, each pixel in the first image is searched for its minimum value, and that value subtracted from all the pixels. Then the maximum value is searched for and every pixel is scaled so that the maximum is 255. That insures that the image has the maximum contrast possible for that image. The image is then saved as a .TIF file, with the same name as the original .SPE file. This process is then repeated for all the images selected.
