Oooppss! This one is actually the result of a bad input file specification in Lab_curves.pfi. I fixed the sample file in the TestImages folder and I took the opportunity to rename it as curves.pfi, since it is more an example of how the curves tool works in general in photoflow.

You should download the updated version of testimages.zip if you want to try it.

To see it at work, open the "curves.pfi" file and then double-click on the "RGB/Lab S-curve" layer: this will pop-up the corresponding configuration dialog. Now toggle the visibility of the "Lab conversion" layer on and off: you should see a different graph in the curves dialog depending whether the Lab conversion is performed or not. Moreover, you will see that the overall result is slightly different in the RGB and Lab cases (with a personal preference with the Lab processing, as it does not get oversaturated).

This shows two features of photoflow:

• you can open any number of configuration dialogs and then change image settings while they are opened (zoom, pan, change visibility, etc...)
• for each layer, the processing is performed in the colorspace which is determined dynamically by the underlying layers; colorspace conversions are treated as any other image processing operation and are applied on-the-fly.

In any case, the handling of missing input image files needs definitely to be improved, as it should not lead to a segfault. I'll see how to fix that.

It shouldn't crash anyway.

[aferrero2707]

I totally agree... I'll keep the issue open until it gets fixed.
