[Geoserver-users] Anti-aliasing still applied on external graphics?

Hello,

I am trying to render a map without any anti-aliasing applied. Disabling it however seems only to affect lines and not external graphics and other symbols. See the layer preview here:

I render lines with thickness 1px and this external PNG:

I discussed the issue on IRC, originally I thought it occurs because the symbols are mapped to non-integer pixel positions, but what I see in the screenshot looks more like anti-aliasing. Is there someone who could elaborate on what might cause this? Also, is there a way to achieve a non-modified rendering, even if it involves a small code patch?

Regards
