wrong coordinates when exporting to XAML

[Jan Krystufek]

There are few bad things in Inkscape to XAML export:
1) Some objects (e.g. rectangles) are on wrong coordinates.
2) After using "Resize page to drawing or selection" function, coordinates of objects are not in new global coordinate system, but in the old one with defined object transformation. (There is not reason for that, because only translation was performed.)
3) If text objects are inserted in drawing, some text object (TextBox) contents disapear during XAML exporting.

Please provide information about your OS/platform and Inkscape version (see Inkscape menu 'Help > About Inkscape').

ad 1) It appears when object was rotated using "Rotate selection 90° ...".

Could you please test with the latest stable build?
<http://sourceforge.net/projects/inkscape/files/inkscape/0.48.3.1/>
or a recent development build?
<http://sdrv.ms/Q2Ls0i>

Several XAML-related reports have been fixed since the release of 0.48.1:

A list of known issues can be found in the wiki:

Attaching sample SVG files here to the bug report for remaining issues would ease further investigation.

I just tried 0.48.3.1-2, but the result was same.

Attaching the file (for convenience).

Issue 1) is likely related to (or a duplicate of) Bug #215534 "SVG to XAML adds offset":
The rectangles are inside two nested groups, each of the groups has an explicit 'transform' attribute.
Might have been fixed in r10010 (trunk only)
<http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/10010>

> 1) Some objects (e.g. rectangles) are on wrong coordinates.

Confirmed. The export process doesn't seem to process nested transformations correctly.

> 2) coordinates of objects are not in new global coordinate system

That's how the SVG coordinates are calculated. I don't know if it's a bug or a wanted behavior, but it's not the extension's role to correct that.

> 3) some text object (TextBox) contents disapear during XAML exporting.

Confirmed. The whiteSpaceCollapse="preserve" attribute is blocking the text rendering. Manually removing it fixes the issue. To be investigated.

[Dion Barrier (nethemas)]

The follow SVG when exported to XAML will see the black slash displaced. Affects v0.92.1 x64 (Windows 10).

[jazzynico (jazzynico)]

The whiteSpaceCollapse="preserve" issue is managed in bug #1521688 (Xaml export. Tag "whiteSpaceCollapse" is not recognized).

Closing as part of migration of reports to GitLab (alpha.inkscape.org/bug-migration/)

Based on the two example files I see attached (and the descriptions), this issue is the same as the (newly) reported issue here: https://gitlab.com/inkscape/inbox/-/issues/2087

[Nathan Lee (nathan.lee)]

Oh, I was wondering where the text issue was coming from! Re-reading the issue, want to add, based on https://bugs.launchpad.net/inkscape/+bug/1025642/comments/8, the text issue was/is being tracked in https://bugs.launchpad.net/inkscape/+bug/1521688
