I noticed that it takes a long time to switch between datasources in AMScanView when the spectra image is very large. On my linux laptop the delay was ~1-2 seconds. The size of the image was 644x2048 which is quite large, but still very possible. especially on my beamline where you could theoretically have a very large EXAFS scan (K > 15) with fine steps.

Do we have any possibilities for faster drawing of large images? Thoughts? Suggestions?
