another question that is probably just due to the exotic or obsolete formatting of an epub. I'm giving you two screenshots, one from Sigil, the other from the epub reader of calibre. Parts of the text are inserted as non-OCR'd image files which I cannot extract as the file type is *.svg - I've never come across this before. The koreader or the firefox epub plug-in or the FBreader cannot display those images at all, so I get an incomplete text. I've manually corrected this by downloading screenshots, OCR'ing them and inserting the text into Sigil. Any ideas?
