DIY Book Scanner

What happened to that version of scantailor that started multiple processes in task manager, one per thread to process multiple pages at once? I'm using the newest one and it processes one page at a time.

Maybe a single page compressed differently? I compressed a whole book and the same issue didn't happen.

I think it was a false alarm. When I view the djvu at 100% zoom the quality is higher than "fit width to the screen". Fit width seems to blurry the edges of everything.

Just noticed something: A single text page, with grayscale or 1bit, results in the same PDF with mixed raster content. Maybe some bytes of difference, but they look the same. However, with djvu the result is different. Grayscale results in a somewhat bold text and 3,5x times increased filesize. It s...

STA 1.0.12. Different hardware doesn't affect the processing, does it?

Why does scantailor erase shaded areas? I'm scanning many math and physics books. There are lots of pages with shaded graphs or figures such as triangles, circles, etc. The shaded area is shaded with black dots with a pattern to make it gradually darker or lighter. Scantailor always tries to clean s...
