[solved] Pixelated blur with 0.46

Postby DannyKing » Sun Feb 17, 2008 1:29 am

Hi all,

I'm having some problems with blur in my build of inkscape. The 'about' screen identifies the build as inkscape 0.45+devel built 5 jan 2008.

My blur effect looks terrible (my preferences are set to 'best' in the filters section) and so do my exports to png with blur.

Here's an exmaple:

Is it something I'm doing wrong?

Also, is there a way to keep to the latest bleeding edge build easily using ubuntu's apt-get system? I think I installed my version though aptitude after using this guy's repository http://my.opera.com/area42/blog/inkscape-0-46-prerelease. Is there a better one that I can't find? (I don't want to compile myself!)

Thanks

Uhm... yea, that's some transformation bug. Basically the blur stuff gets drawn nicely to a pixel buffer and then it's transformed, which introduces these artifacts.

File->Inkscape Preferences->Transform->[x]Optimized

Using that setting should make it more unlikely to appear. If you now rotate it back n forth a bit the transformation should be gone (well, the transformation is directly applied... there is no transform attribute anymore).

If you don't want to move it around you could for example add a little bit of geometry (a bit away). I suggest using a small rectangle. Then Path->Union. And then delete that rectangle again with the Node tool :tool_selector:

After that the transformation should be also applied to the path and blurring it (or a clone of it) should look fine again.
