It looks like your image's colorspace is `None`, so pikepdf doesn't know how to handle it. On which page in that long document is this image, anyway?

Thanks for the illustrative write-up. Yes, improved auto dewarping in ST would be nice. ------ User hint: There's an old windows program "BookRestorer v4.2.1" from i2s which seems to provide...

> Simple dewarping: I viewed the examples, but this does not seem to be what I'm looking for. I don't think this can compete with ScanTailor's flexible mesh dewarping.

> What you are looking for is implemented in [STEX](https://github.com/ImageProcessing-ElectronicPublications/scantailor-experimental). But for this, @Tulon had to throw a lot out of [ST](https://github.com/scantailor/scantailor). Yeah, I know. STE is the variant I'm...

Question though: How does https://github.com/ImageProcessing-ElectronicPublications/scantailor-experimental (A) differ from @Tulon's https://github.com/Tulon/scantailor/tree/experimental (B) ? I see that (A) is not a GH fork of (B). History and directory layout don't match. Who...
