Hi, I'm not sure whether the following is an issue with ConTeXt or with the epub readers I'm using; my apologies for the noise if it's not relevant to this list! I was experimenting creating ebooks with ConTeXt, and found it works very well on most epub readers (except with Calibre, as was previously reported on this list) as far as text is concerned, although I am having issues displaying images. Images appear correctly in the exported html file when opened with Firefox or Chromium, so I suspect the issue may either come from difference in specs for the epub and html formats or from bugs in the epub readers I have tried (Mupdf, Koodo, and Foliate). Example showing the issue: _____________________________________ % test.tex \setupbackend [export=yes] \setupinteraction [title={\documentvariable{title}}] \startdocument[title=Test EPUB] % Some text \samplefile{tufte} % Include a simple MetaPost image \starttextdisplay \startimage \startMPcode fill fullcircle scaled 3cm withcolor darkred ; \stopMPcode \stopimage \stoptextdisplay % Some text again \samplefile{tufte} % Include an equation as SVG image \starttextdisplay \startimage \startformula e = \frac{m c^2}{\sqrt{1 - v^2 / c^2}} \stopformula \stopimage \stoptextdisplay \stopdocument _____________________________________ I compile it using _____________________________________ mtxrun --script epub --images test.tex context test.tex mtxrun --script epub --make test.tex _____________________________________ Render from Koodo 1.5.1 (correct): https://pasteboard.co/4bUcUdaJim9m.png Render from Koodo's latest version (1.7.2): https://pasteboard.co/xRfDCYx9zki4.png All recent epub readers I have tried (Mupdf, Foliate, Okular) produce a similar incorrect rendering. I am not very familiar with the epub format specs so I don't have a good feel for where the issue may come from. It seems that manually adding <img alt="image-1" src="../images/test-exported-1.svg"> in the .html file makes it appear with recent epub readers, though. Is it possible to have the html output generated by ConTeXt include images in this way (or tune the way images are included in another way which may work better with recent epub readers)? Cheers, Florent
