Question: Calibration Issues with larger images

Anmar is asking a question about spectral-workbench: Follow this topic

by Anmar | August 19, 2016 22:22 | #13371

Is anyone else having troubles with the calibration functions on the site? When attempting to calibrate a spectrum using copy calibration the graph remains greyed out and nothing happens. when trying to manually calibrate the spectrum I get the error "The tag you've applied couldn't be saved, but it's been run locally. Clear it now."

I have the same problem.

I tried on various browsers, from various locations (through VPN), though various networks, at various times of day, to no avail. I would really appreciate a pointer, or even someone saying that it works for them. https://spectralworkbench.org/spectrums/115667

Hi, Johnix, its possible the source image is too big. Can you tell us it's dimensions in pixels? I'm sorry youre having trouble!

Hi Warren, thanks for replying. Yes, that's quite possible. The picture is 3456*4608 pixels, 1.25 MB (taken with a recent smartphone)

I tried again with the same image at 1080x1440, no success.

I further reduced it to 540x720, and I was able to run my calibration. Thanks a lot for the tip!

Super helpful. Thanks and there is an issue filed for getting it to accept larger images: https://github.com/publiclab/spectral-workbench/issues/104
