I wish have the bitmap in rlu, but i guess it is not possible... So first of all I wish to know if it is possible to convert the file from xrdml to xyz table for plot it with origin lab.

The second question is how could I improve the resolution of such plot. I made the origin lab notebook by adding arround 23 xy tables (from 23 step omega scans V.S. continuos 2q/omega scans) to origin and then making a contour map. The problem is when I make a zoom, the level lines are visibles clearly in diferent colours (so that different intensities), but in the whole map they are not more distinguishable but a black spot, so I lose the information about the intensity.
