Fit2d is perhaps the 'gold standard' for making powder diagrams:

Subject: [ccp4bb] I vs. 2theta plot, image processing
1) Some data collection and image processing files have the options to show the intensity
distribution over a user-defined "line" in the image. 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?
Thanks,
Lucas Bleicher
