309036 - JPEG, GIF, and PNGs are not correctly scaled in <svg:image>

Status: RESOLVED WORKSFORME

(Core :: SVG, defect)

Description

[Christian Balkenius]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

Bitmapped images included with <svg:image> are scaled as if there was an extra
white border of 1 pixel to the right and bottom of the image. This makes the
image fade toward white in these directions (This is particularily disturbing
when very low resolutiom images are scaled up). For GIFs, this effect changes
when the same page is reloaded several times. (This may related to that an image
looks the same in JPEG and PNG, but will look very different as a GIF).

Reproducible: Always

Steps to Reproduce:




Example:

<image x="10" y="10" width="256" height="256" xlink:href="color.jpg" />

Testcase?

Christian Balkenius, could you please attach and image and SVG showing the problem to this bug?  First attach the image first, point the SVG to the bugzilla attachment, then attach the SVG.

Could this be caused by https://bugzilla.mozilla.org/show_bug.cgi?id=324698?

Confirming with Firefox 1.5.0.1. Issue should exist on trunk as well (as there it even happens with an HTML img element now due to bug 324698) but my trunk nightly Firefox build (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060331 Firefox/1.6a1) refuses to show the GIF image elements in the test case at all.

WFM now in trunk builds.

We should have a test for this.
