Font rendering Gimp 2.8

[nuxio]

Hi there,

I noticed some problems with gimp 2.8.0.
When I used this version of gimp with Fedora 17 beta and Arch Linux, there are some problems with the font rendering when anti aliasing is turned on. Without the Infinality patches the font just renders normally, but after installing freetype-infinality I get some green/blue borders around the text (see attachment). If I turn anti aliasing off in gimp the text renders normally again.

Currently installed:
- fontconfig-infinality
- freetype-infinality

Current OS:
- Arch Linux x86-64

I am able to duplicate your issue. I'll need to investigate. Thanks for the report.



EDIT: This is a strange issue. I can turn off all the enhanced processing and it still results in this problem. I'm having trouble finding the source of this.

Hmm strange.

I wish I could help finding the source, unfortunately I have really no idea how font rendering etc. works. The only thing I noticed was that with Archlinux default freetype (freetype2 2.4.9) this problem did not show up. So I guess it should be in one of the patches or the freetype version you (or someone else) applied the patches to.

If I find something noticeable, I'll let you know!

The problem doesn't seem to happen with black text on a white background, so as a workaround, you could do that, and then invert the image.

Indeed! Thanks for the workaround!

I had the same problem, and my solution was to change the subpixel rendering to v-rgb in 50-base-rendering-inf , and problem solved. But the looking was ugly, not totally ugly, but not like the original configuration and the fonts do not render well, so removing the section
<edit name="rgba" mode="assign">
<const>rgb</const>
</edit>
In the same 50-base-rendering-file, was a good solution for me.
In archlinux x86-64
