  1. Diffraction Image Library F. Remacle & G. Winter

  2. What is it? • A C++ library to access data of various formats of diffraction images in a standard way. • Originally developed for DNA and XIA, now being developed further as part of the CCP4 library.

  3. What can be done with it? • Reading images from the following detectors: • ADSC (all) • Rigaku: R-AXIS IV, SATURN • Mar: MAR300, MAR345, MARCCD • CBF (in development) • Bruker

  4. What can be done with it? • Access to “standard” information • Beam centre coordinates • Distance to detector • Wavelength • 2 Theta value • Exposure time • Image size • Collection time • Pixel size • Oscillation range • Image data (pixel values)

  5. What can be done with it? • Different calculations (histogram, asymmetry, corner, radial profile, gain) • Writing image data as jpeg or ppm. • Peak finding and other peak operations with the PeakList object. • Available as Tcl and Python modules!

  6. Who is using it? • Me, for writing a Tcl new version of ipdisp. Now called idiffdisp. • xia2 currently wraps compiled programs built on the library, but will use the python module directly in the future.
