How to test that it is improperly rendered:

const sharp = require('sharp');
sharp('fixtures/avi.input.svg').png().toFile('1.png');

The output file is completely blank. The expected output is an "AVI" text.

Expected output (screenshot from a finder)

Hello, it looks like librsvg might be having problems with the transform property of the clipPath element. Removing the transform and setting its x and y properties to zero works.

-  <clipPath id="clip-path" transform="translate(-36 -710.64)">
-    <rect class="cls-1" x="36" y="710.64" width="72.171" height="40.896"/>
+  <clipPath id="clip-path">
+    <rect class="cls-1" x="0" y="0" width="72.171" height="40.896"/>
   </clipPath>

The next step is to try to reproduce this using the rsvg-convert command line tool from the latest version of librsvg.

[lovell]

Using rsvg-convert v2.40.20 generates the expected output but v2.45.4 generates a blank image so this looks like a recent regression introduced into librsvg.

Please can you report this upstream at https://gitlab.gnome.org/GNOME/librsvg/issues

[lovell]

Has anyone reported this upstream? (I had a quick look but couldn't see any related issues.)

[lovell]

Closing as there's nothing sharp or libvips can do. Please report this upstream at librsvg if it continues to be a problem.
