I have a few files in .djvu format, which size is small, but unfortunately mi e-reader can't display it. I use DjvuToy to transform it to PDF and it keeps the small size; but then, when I use Abby FineReader to do the OCR and save, the size increments about eight times (this only happens when the file includes color or grayscale images). So, I figure that it would be possible take the second file text layer and add it to the first so I can get both the small size and the OCR. How can I do that?
Note: The original djvu file does not have text layer, although it would be nice to know how to convert from djvu to pdf including text directly.
