[LegeApps]

I am fine with a move but it has a lot to do with KoReader, because standard Kobo software doesn't support DjVu and has issues with JBIG2. So the program is explicitly designed to work with KoReader which supports those formats, and more, well.

And the commit you showed does not do the same thing as my program. it's in the name; it isolates the SMask. Many raster scans aren't masked at all so there is nothing to isolate, that's why they need to be rendered, or the images otherwise extracted. Rendering is faster. It also does not and cannot support layout detection to prevent images from being thresholded.

It is a good feature and I support it but it is not the same thing.

edit - i am implementing this in Lege now. it wasn't possible before i had control of the renderer. internet archive MRC type scans will retain their original text layers. removed some stuff i said about thresholding; this method doesn't threshold at all. it just uses the jbig2 smask layer, clean and easy for a subset of scanned book types (not all).
