App does not accept SVG files created in Inkscape

[wessven]

I haven't been able to get any SVG files created in / saved from Inkscape to import in the Chance app. When I try to load the image, the app gives a message "Invalid SVG".

The files are saved as "plain" SVG conforming to version 1.1 of the spec, not the Inkscape flavour of SVG.

According to the svgcheck utility, the file is valid SVG:

(svgcheck)$ head test.svg
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!-- Created with Inkscape (http://www.inkscape.org/) -->

<svg

validator.nu also shows that the file is valid.

The app does load an SVG file created in Adobe Illustrator, even though the svgcheck utility does not think it is valid SVG:

(svgcheck)$ head test2.svg

I've been using v1.4 of the app.

Attached is the SVG file that I created in Inkscape.

Hi - thank you for taking the time for reporting this, and in such a detailed way.

I will investigate now and update this ticket as I progress.

OK - I've coded a unit test (with this svg) and found that a function I wrote is too tight it how it expects the svg file contents to look.

All the other images I use - most of them I created in Inkscape - are formatted slightly differently than yours. This is why my tests didn't pick this up.

I've relaxed the affected function; all tests pass; and I did a quick manual check, and things seem OK:

I've tagged the code, and F-Droid should pick up the new release - 1.4.1 - in a few days, or so.

I'll keep this issue open for a week or so, just in case anything else related crops up.

Apologies for the hassle I've caused you - the app is early in its lifecycle, so bumps like this are, alas, kind of to be expected.

Thank you for helping make the app better :-) I appreciate it.

Great, thank you for the quick response and prompt action! Glad I could help, and thanks for making this. :-) Going to use it for generating story scenarios for my kids.
