Kobo Software Disregards Ebedded Fonts in SVG Images

Hmmm, maybe you are doing something wrong. Could you post here one of your .svg images? I'd like to do some experiments on Inkscape with it.

I wasn't sure what you were looking for, RbnJrg. So I attached a sample epub and two SVGs in a zipped folder.

The epub has SVG images of tables, charts and blocks of formulas.

The two SVGs in the zipped folder are the two files that I referred to in my post yesterday in which I tried converting to paths. I converted the chart in one step using Path/Object to Path. I used Path/Object to Path to convert each text string in the table individually to a path. I included the PDFs from which the SVGs were created in Inkscape, too.

The files beginning with a3f01, a3f02 and a3t01 are the SVGs with emedded fonts.

"Replace PDF fonts with closest-named installed fonts" was left unchecked when I opened my PDFs in Inkscape. I found that by leaving this unchecked, my embedded fonts were recognized by Kobo and ADE when opened as epub. When I left that option checked, no program or device recognized the embedded fonts.

I tried changing the font setting to "Document Default" but it had no effect on the kepub.

Thanks for the suggestion, though.

Update #1:

I just tried it on Nook Android. That app disregards the embedded fonts when using the user's preferred font but it recognizes the embedded fonts when set to "Document Default." And for some reason, it centers the figure numbers (i.e., image captions) when set to "Document Default" but not when the reader's font is selected. The CSS I used is supposed to center the captions and it does in ADE and all the various Kobo methods I've tested.

Update #2:

I tried Nook PC today and everything works as it should plus it looks great!

I found "Select All" in Inkscape. I must not have had enough caffeine the other day. That worked for converting all the chart elements to paths but it still left all the font details in the SVG file, although they don't seem to be doing anything. I just searched and deleted all the font specs and the image looks just the same. So that will work.

But now I've stumbled onto a new problem. Only the Nook tablets and Nook apps support SVG. I should have looked at B&N's requirements sooner. They say the only supported file types are JPG and PNG. I naively assumed that they were at the cutting edge and most likely ahead of Kobo. So now I'm trying to figure out if Nooks can handle PNGs in SVG wrappers. That's definitely not a good solution but it should be better than letting the HD devices scale my PNGs.

I'm starting to get the idea that by the time I get this figured out, the firmware for the various devices will have caught up with the times and I'll be able to use SVG anyway. But that will probably be later rather than sooner.
