SVG images marked as "unused media"

AlanHK · 09-02-2016, 12:11 AM

I inserted an image using the "AddImageasSVG" plugin.
Looks fine.

Then I ran the "Delete unused media" tool.
It wanted to delete the image I had just placed.

The page is

Code:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
  "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <title></title>
  <style type="text/css">    @page {padding: 0; margin:0}
body  {text-align: center; padding:0; margin: 0; }
  </style>
</head>

<body>
  <div>
    <svg xmlns="http://www.w3.org/2000/svg" height="100%" preserveAspectRatio="xMidYMid meet" version="1.1" viewBox="0 0 616 444" width="100%" xmlns:xlink="http://www.w3.org/1999/xlink"><image width="616" height="444" xlink:href="../Images/map.png"/></svg>
  </div>
</body>
</html>

If I add a line above the </body>:

Code:

    <p><img src="../Images/map.png"/></p>

Then that makes it "used".

However, the cover image is also SVG, from the "Add cover" tool, but it is not marked for deletion.

I'm certainly not an expert on Sigil programming code, but I would hazard a guess that when using the "Add cover" tool it also semantically defines that image as the "Cover" thus identifying it as used. Whereas the plugin doesn't have another way to force sigil to recognize it as being used. I would therefore bet that Sigil is only looking for the <img> tag instead of the <image> tag when determining if an image is being used.

That would be my guess FWIW....but I'll let the smart guys actually look into it!

Seems to be the case.

If I remove the "Cover Image" semantic tag from cover.jpeg, it also now is "unused".

I haven't been able to reproduce this behavior with Sigil 0.9.6.
Are you using an older Sigil version or a portable Sigil version?

DiapDealer · 09-02-2016, 08:49 AM

I can't reproduce it with 0.9.6 on Windows (not with the latest developer build either). Can you post some detailed steps (if you are indeed using 0.9.6)?

This sounds vaguely familiar--like maybe an older bug that has since been fixed--but I can't seem to find it.

EDIT - Perhaps this one from the 0.9.4 changlog:

Yes, this was a bug fixed in an earlier release. If you are truly seeing this bug in Sigil 0.9.6, please provide step by step instructions on how to reproduce it.

If you are using a version older than 0.9.6 (see the About menu item for info on Sigil version), then upgrading to the latest version should fix this issue.

Thanks,
