eBook Previews from Calibre
Posted: 01 Sep 2015 14:32
- I manage a (personal) huge collection of ebooks, and heavily rely on previews
- It depends on multiple plugins (acrobat reader + fix for previews, epub, mobi, djvu, some azw(3or4), cbr/cbz)
- Calibre (http://calibre-ebook.com/) has a command line function to easily extract covers as JPGs for many ebooks formats:
ebook-meta --get-cover Cover.jpg "3D Printing with Delta Printers - Charles Bell.azw3"
- Would it be possible:
- To have a check box in preference to either use OS provided or Calibre output (in which case it would check calibre availability or redirect to the website)
- For the supported formats to replace the Windows provided thumbnails by the output of the calibre function (probably scaled down to a max of 256 pixels to save space?)
- Maybe storing them an invisible ".XYPreviews" directory in each directory, containing jpgs with the same name as the ebooks themselves, so it can be easily flushed/refreshed/prunned
- ebooks covers are unlikely to change, but just in case, an auto refresh function comparing modified dates of ebooks vs creation date of jpegs?
- Context menu to force a refresh of a particular ebook?
- For extra speed, Generate first ebooks displayed in the pathfinder visible area, then continue with others in same directory in the background
