Attachments: SVG from Blender which crashes Krita on import

Description David Faure 2010-12-17 19:41:15 UTC 


---- Reported by bugsbane@gmail.com 2010-05-19 06:56:33 ----

Application: krita (2.3 Alpha 1)
KDE Platform Version: 4.4.3 (KDE 4.4.3) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.33-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
Any time I use blender 2.5's "Export UV layout" to .svg and try and open it in Krita it brings up the import dialogue, but on clicking "OK" it crashes. The odd thing is that despite the image being square, that the width is reported as 1 pixel while the height is reported as 470 pixels. I can open the same .svg without problems in Gimp / Inkscape. I can also open .svg's made in Karbon and Inkscape fine.

I'm using Krita revision #1127876 with QT 4.7.0 beta 1. Example crasher file to follow.

The crash can be reproduced every time.

SVG from Blender which crashes Krita on import



---- Additional Comments From boud@valdyas.org 2010-05-19 08:55:33 ----

The crash is actually an assert inside KOffice's core flake library. Krita cannot load .svg directly, I think think it's converted to .odg first -- and if that would succeed, it might be converted to something else again, since I doubt it will be imported as a vector layer at the moment. I'm fairly sure we actually use Karbon's svg filter in this procedure.



---- Additional Comments From cyb@lepi.org 2010-11-21 11:55:14 ----

I get the assert when opening with karbon as well.



---- Additional Comments From zander@kde.org 2010-11-21 12:50:19 ----

Cyrille; is the crash you get in karbon also showing this in the backtrace;
 koffice/filters/karbon/png/PngExport.cpp:70

either way; I suggest re-assigning to karbon filters.

I am unconvinced that the bug is in karbon, there is little evidence for that at the moment.



---- Additional Comments From zander@kde.org 2010-11-21 16:06:53 ----

The backtrace in the context of this bug tells me that the boundingrect of a KoPathShape was invalid (likely containing NaN).
There are two ways this can happen; one is the shape was manipulated (sheared etc) incorrectly from flake or other code. With values that were NaN.
The other is that the karbon SVG parser is doing something wrong. see koffice/filters/karbon/svg/SvgParser.cpp 

I'm placing my bets on the latter.  Anyone investigating will want to check calls to KoShape::setTransformation and check if the argument is a valid transform.
For example by doing;

#include <qnumeric.h> 
QPointF p = matrix.map(QPointF(10, 100));
Q_ASSERT(!(qIsNaN(p.x()) || qIsNaN(p.y())));

Fix crash in loading svg file from blender

The svg file blender writes out contains a viewBox with wrong content

<svg width="2048px" height="2048px" viewBox="0px 0px 2048px 2048px"
     xmlns="http://www.w3.org/2000/svg" version="1.1">

Workaround the bug by removing the px from the viewBox string before loading
the viewBox values.

Fix crash in loading svg file from blender

The svg file blender writes out contains a viewBox with wrong content

<svg width="2048px" height="2048px" viewBox="0px 0px 2048px 2048px"
     xmlns="http://www.w3.org/2000/svg" version="1.1">

Workaround the bug by removing the px from the viewBox string before loading
the viewBox values.
