[flint] Allow to display more than 20FPS for fast detectors
(from an email from J. Wright (ID11):
To follow up on the frelon image viewer needs:
- "Fast" scans are about 6 fps with 8 MB images
- This saturates the network but is slow enough to watch
- Rebinning and mapping to "char" in C takes ~2-5 ms on lid11frelon1
- Lossless compression of that with zlib is more like 10-50 ms (depends on image)
I put some code on http://github.com/jonwright/image_trans to measure timings, probably you can >make it much faster (I didn't try jpeg).
For a live display we want to see a picture that changes faster instead of the 'full' image changing slowly. Can we have something like this as a LIMA thumbnail plugin and integrate it in flint please? We also need to remove a background, and divide by a flat, and get control of the color-mapping (set the max, min, log, linear, sqrt scales) to be able to see our signals.
For 1D cuts in the image we would still want to see the real data to get an idea of the actual signal/noise level.
Is it feasible?
