Bug Description
Binary package hint: firefox-3.0
Summary:
when using Menu -> View -> Zoom -> Zoom In/Out, images on web page are also rescaled.
the images are obviously not rescaled using nearest neighborhood algorithm, but the image has less quality than image rescaled by gimp using linear algorithm. see http://
I don't know which algorithm is used, but linear would be sufficient.
firefox version: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.7) Gecko/2009030422 Ubuntu/8.04 (hardy) Firefox/3.0.7
Steps to reproduce:
1. Open the following URL: http://
2. Select menu: View -> Zoom -> Zoom In
Expected result:
The image is scaled up.
Actual result:
The images is distorted when scaled up: the white and yellow markings on the road in the photograph show the distortion clearly. The following screenshot has some areas of distortion highlighted: http://

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, after trying to reproduce on Jaunty with different images including yours, I find it difficult to identify what the expected behaviour should be compared to what it actually does. Could you please attach your screen shots to this bug and highlight in the Firefox resize screen shot what aspect of the resize you think is not handled correctly?
