"Illegal flood fill seed coordinates" Error when Opening Older Workspace

[jfoster]

I opened a workspace from May of 2022 and got "Illegal flood fill seed coordinates" errors from a mask created within a Composite transformation. I upgraded my computer last summer, and going back to my old computer I was able to see an error-free workspace on it (reloading PWP 8.0.331), so I have a work-around for this image and this is not a pressing issue for me at this time.

I was able to minimize the number of transformations to the bare minimum that reproduces the problem. I have also replaced the original tif format files with highly compressed jpg versions of images. These proxy images also reproduce the problem, and allow the workspace and images to be zipped into a file-size within the forum's upload limit - see attached problem workspace.

There is actually a problem with one of the flood fill mask operations in the workspace file you posted, namely the seed coordinates for one of the flood fills lie just outside the image. Older versions of PWP did not check for this error when parsing the stored command line.

What I can do for the next release is make this error a warning instead. As before, if the seed coordinates are outside the image, the associated flood fill operation is ignored. It looks like newer PWP versions no longer let you place seed points outside the input image.

As before, if the seed coordinates are outside the image, the associated flood fill operation is ignored.

Sounds good (and backward compatible).
