Hello folks,
I need to remove a background image when converting from pdf to epub.
This background image is like a old paper with stains and points pretending to simulate an old document.
When converting a similar document without this "noisy" background the epub file is about 500KB from a pdf of 1MB. But with this background the epub file size grows to 30MB.
How may I filter this background? Is there any special option in Calibre to do this task or should I edit the pdf file before conversion? In the later case, which SW may I use to edit the pdf using Ubuntu?

Thanks
