Hi Lucas, There is a C++ library called DiffractionImage which may help with #3 if you get that far:

Does any program allow one to trace a line from the beam center to the detector edge and save this intensity distribution to a file, so one could have I vs. 2theta data (or even a I vs. pixel data file, which could be easily converted to a I vs. 2theta file given the experimental setup)? 2) Is there a program which could convert image files from common 2D detectors (Mar345, MarCCD, RaxisII...) to a text file with the intensity on each pixel so one could easily write programs to do things such as in (1)? 3) If the answer to 2 is "No, you should learn how to handle binary files and image data formats", is there a tutorial on how to do this (I would prefer C/C++, but Fortran is OK), or some well-documented open source code I could study?
