Calibre limit how many pages to convert

[jorm]

Summary
Looking for a way to limit the number of pages calibre's ebook converter converts since I want to use it for scanning for the isbn number.

Detailed

I am trying to write an isbn extractor for my books so I can update the meta data based on it. I prefer not to use the filename since that will not result in a 1-1 match. Since I plan on trying to do a lookup based on the isbn with google books to get the meta data I want a 1-1 hit.

i have written something in C# so far that works for pdf, txt and epubs natively and will convert the first 10 pages or until it has found the isbn number. And that is all working fine. However I would like to expand this to do mobi and lit.


I was planning on trying to use calibre's ebook converter since it can handle almost any format. I was trying to find out if anyone has a suggestion on how to modify the py to only convert x pages. I don't want to convert the entire book since that will make the process of tagging my collection take 20-50 times longer.

Once completed I was going to open source the code so people can tag their own collections.

I think this plugin functionality already exists https://www.mobileread.com/forums/sho...87&postcount=1
