Re: [Pharo-users] Create PNG (from pdf?)

Hi Franz Josef, thank you. Torsten Bergmann recommended http://pdfbox.apache.org/ to me and I am just playing around with it. My first impression is, that ImageMagick has more features. It is great to have 2 promising alternatives. I will have a look at it, too.

It is not the first problem feedback I heard on ToC menu, maybe the generation of ToC is corrupt. I will have a look at this one.

I sent the epub to my Kindle (converted to mobi by Calibre).

In our editorial system we use ImageMagick for this task. I guess you have this option on your list. If not, have a look at <http://imagemagick.org/discourse-server/viewtopic.php?t=19432>. I only can state, ImageMagick is doing this job reliable at over 1000 clients.
