Bug Description

Most of the effects not work, e. g. Black and white, Invert Colors, Clouds, Bulge, Twist. If I apply them, the image remains unchanged. Effects that still work: Edge Detect, Relief.

Package versions:
- pinta 1.1
- gtk-sharp 2.12.11
- mono-addins 0.6.2

Tested also with the latest version of Pinta from GIT with the same result.

I have tested effects you described as not working in:
- Pinta 1.1 on Windows XP and
- Pinta latest version from GIT on Ubuntu 11.10
and on both system everything is working as designed.

Can you please provide what is your operating system and version. Can you also provide more info: have you draw a new picture or opened some file and executing effects on it. Can you attach the file you are trying to create effects on.

The system is Arch Linux. The result is the same if I open a picture or start drawing a new one. I can see the effects on history panel but the picture remains unchanged. And I don't get any error messages or exceptions.

i agree - most Effects do not work. they appear in history but produce no preview or changes to the image

still with Macintosh OS X.7 - Lion. Pinta1.3

running in MonoDevelop there is no error from "Gaussian Blur" - but no image results either.

the Effect "Edge Detect" produces this error -

I agree as well. Most effects do not work at all, no supicious output in the console.

Arch Linux x64, kernel 3.4.3, mono v2.10.8-1, mono-addins 0.6.2-2, gtk-sharp-2 v2.12.11-1 => from official repos, pinta 1.3-1 from AUR.

I agree with other people - most effects do not produce a result, and no console output is apparent.

Okay, I found that this commit in gtk-sharp causes the problem:

It was committed in the 2.12.11 release of gtk-sharp, so systems with 2.12.10 or older (e.g. Ubuntu) are not affected.

So could somebody check why this commit breaks the effects in Pinta?

Thanks for the fix! I experienced problems with Fix Motion Blur and Pixelate effects due a typo and an infinite loop. The attached patch fixes this issue.
