Sorry: It's because I started this journey with Calibre to turn PDF into EPUB. After seeing that my e-reader could actually read PDF rather well except complicated layouts such as tables, I figured I could just turn those pages into bitmaps and generate an hybrid PDF (text/bitmaps).
And then it dawned on me that k2pdfopt made all this useless since it can massage the whole file.
As for the particular PDF I sent: It looks perfect on the computer (SumatraPDF), but on my 6 inch e-reader (768x1024, 212 DPI), some pages are a bit messy although, strangely enough, those only contain only text, in one column.
I used the command above:
Code:
k2pdfopt -mode fw -ls- twilight.pdf
Why does it occur, and what could I try?
