Tricky one this. The color transfer filter imports/loads the image in the process methods. Since we try to process the filter in chunks for the preview, we try to load and delete the image many times in different threads -- and that's not going to work. The filter should probably be rewritten to store the image itself in the settings and pass that to the process method.
actually, all you need to store is the mean and sigma of L,a,b channels of the reference image. And compute them only once when opening the image in the filter widget.
Git commit 0a3fa8fb560dc983bf682fe1f4680747ebb45f47 by Boudewijn Rempt. Committed on 18/07/2011 at 11:14. Pushed by rempt into branch 'master'. FastColorTransfer: compute mean and sigma and store those in the config We used to compute mean and sigma for the reference image in the process(). This is wasteful, so compute those only once and store the values in the config object.
