Abstract
A program is described that deals with a frame
image in protein crystallography. This program is
developed in order to display the diffraction image,
to integrate the pixel data, and to reduce to structure
factors obtained by use of the Weissenberg
camera installed in Photon Factory. Use has been
made of the library of X-Window and X-Toolkit for
the man-machine interface parts in the program,
which makes it highly interactive. The program has
been written in the C language for UNIX machines
and is portable to almost all kinds of graphics
workstations.
