Spurious link after images with some readers (Baka-Tsuki)

[typhoon71]

In sumatrapdf there's a link after every image.
Happens to both the images at the start and those in the middle of chapters.
Doesn't happen in calibre (or sigil, but that's not a reader).
I checked in icecream too: the starting images are replaced by a bunch of links, exept the cover which is fine; the images in the middle of chapters are fine too.

Can i get a screenshot please

I'm going to assume however that said readers are attempting to parse random url's as <a> tags from what you are saying (which is NOT standard behavior and is a bug in these readers if they are).

The contents of the desc tag are also not supposed to be shown to the user via the reader unless the image has not been rendered. See https://developer.mozilla.org/en-US/docs/Web/SVG/Element/desc

When the current SVG document fragment is rendered as SVG on visual media, desc elements are not rendered as part of the graphics.

This means that if an image exists within the svg and has been loaded then the desc tag is not rendered.

So i do recommend reporting these as bugs to the epub readers developers. Because we do not create svg elements unless there is an image.

This is a wontfix on our end if so @dteviot as our usage is perfectly valid.

OK, I suppose it makes sense to file a bug to those readers (or maybe check if there's some more recent releases of them).
I suspected it could be something on the reader side since sigil was ok. But I hoped... :P
Btw, do you have any suggestion for an epub reader that is complaint?

[belldandu]

Well i always recommend calibre because its usable on even mobile (although some features are disabled until you buy). However i do still recommend reporting these bugs so that other people do not experience the same issues.

Feel free to link to this issue when reporting said bugs.

OK, good to know calibre is loved.
Also, thanks to this I noticed my calibre wasn't up to date so I'll test again with the newer one and if the issue persist I wil report the bug to them. l suppose I can link your answer right? (the stuff about the standard)

[belldandu]

Yep

@belldandu,
I agree that our behaviour is perfectly valid.
However, there may be people who can't update their readers and this will be fustrating for them. So I suggest we add an option to "Not include source URL in images", or something like that. Not a high priority however.

[belldandu]

@dteviot if we do that than it should be a part of #14

[dteviot]

@belldandu.

if we do that than it should be a part of #14

Agreed. Plus, we've got a request to do so.

[belldandu]

Sorry tagged that wrong.

[dteviot]

Added option to turn off the description in the tag.

Added bug in reader tag because of sumatrapdfreader/sumatrapdf#567 No need to reopen this issue.
