Firefox and bad image zoom

Hi to all,

Compare these images:

Zoom with Firefox under Linux

Zoom with Google Chrome under Linux

Firefox under Windows

(image taken from: http://www.tomshw.it/cont/articolo/cons … 26/13.html )

as you can see:

* Firefox under Linux: image zoom is done without antialiasing
* Firefox under Windows: image zoom is done with antialiasing
* Chrome under Linux: image zoom is done with antialiasing

is there any way to fix this issue with Firefox under Linux?

Google reveals much info. Look at the firefox and ubuntu bug trackers, both have extensive discussions about the issue.

Btw I really don't like to have antialiasing when zooming images (even if the example above proves that can be useful, for pixel art it really looks bad), is it possible to disable it in chromium?

Hi,

I'm not sure if I get your meaning here.
I googled around, and I find mostly references to font problems - which is not the issue here - and the imagezoom.defaultGlobalZoom setting, which does not seem related to activating / deactivating antialising for images when zooming.

I have the same issues as trapanator. FF in arch64 does not apply antialising to the images when zooming, but opera does. Also FF in windows does. I took a look in the PKGBUILD, but did not find anything suggesting that the antialiasing is disabled at compile time - so it seems to be a configuration issue.

Any ideas?

Thanks!

Best regards,

Eduardo

One more thing, I found that there is an option:

However, the default value is "auto", which should enable bilinear filtering of the zoomed images.
This really seems to be a bug in the Linux version

On the other hand, to disable the smoothing:
