Hi all, in my attempts to validate epub export from my context source, I made the following changes to back-up.lua and mtx-epub.lua 1) the actual context language is put in the epub 2) changed the OPS directory to OEBPS. The 2.0.1 Standard does not actually say that is has to have that name, but I only found examples using that one, including the sample documents in the 2.0.1 white paper. 3) changed opf:scheme to UUID, since that is used and not a ISBN number 4) added the encoding info in the opf file 5) changed the single in double-quotes in the opf file manifest. I do not know if it is necessary, but this seams to be more consistent Andy diff back-exp_old.lua back-exp.lua 2370a2371

Hello all, I am thinking about the best way to implement the cover image for the epub. This is a mandatory requirement to work properly. The cover image is not necessarily present in the pdf version of the document and it might be the only item where that is true. So I tried to sort out the options. 1) Always take cover.png in the current directory; not very elegant 2) add cover={…} to \setupinteraction; hijacks the pdf interaction macro 3) add a \setupepub; might be overkill, but maybe more options are added later 4) ? Then, the image is taken, renamed and copied in the image folder and finally a html page containing the cover is created. This part is straightforward. It would be great, if someone could come up with an elegant idea how to add the cover image file that is compatible with the context style.

Hello all,

I am thinking about the best way to implement the cover image for the epub. This is a mandatory requirement to work properly. The cover image is not necessarily present in the pdf version of the document and it might be the only item where that is true. So I tried to sort out the options.

1) Always take cover.png in the current directory; not very elegant 2) add cover={…} to \setupinteraction; hijacks the pdf interaction macro 3) add a \setupepub; might be overkill, but maybe more options are added later 4) ?

\setupbackend[coverimage={....}] Backends other than epub can safely ignore the directive. In one of your earlier threads, you had talked about taking title, author, etc from setupinteraction. It might be better to take then from \setupbackend as well (will work for both epub and xhtml backends, perhaps also for xml). Aditya

better is \setupexport (actually, we do have \setupdocument which makes een more sense: (1) take from setupdocument (2) if empty take from setupexport (3) otherwise take from setupinteraction

Indeed, I realized that this morning but had not time to look into it yet. The interaction title is normally a simplified one used for referencing or document info.

filter the first page of the pdf and convert it to svg or png (which is what I did a couple of times) ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Best send me a patched mtx-epub so that I can do a visible diff (handier 
than decyphering the mail).
