713904 - New background color for image pages unusable

Status: RESOLVED DUPLICATE of bug 713230

(Firefox :: General, defect)

Description

[Lars Viklund]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:12.0a1) Gecko/20111228 Firefox/12.0a1
Build ID: 20111228031049

Steps to reproduce:

I opened a PNG or SVG file, expecting to see it against the usual white background.


Actual results:

They display against some dark gray background, making them pretty much unreadable.


Expected results:

It should be showing against the usual background color, not the forced dark gray from bug 376997. I echo the ignored comments in that bug that the color should be configurable and that the default should be one for which alpha composition makes sense. Pretty much all images authored for web usage are designed with a white matte as reference.

Lars: do you really see a non-white-background with an SVG file?

SVG should still use the usual white background, because SVG is treated as a document (not an image) when viewed directly.  That's how it behaves in my nightly, at least.  If you see other behavior with SVG, that would be very interesting...

Also, :emk, I don't think it makes sense to dupe this to the bug that caused it.  Bug 713555 sounds like a better dupe-match to me (using an adaptive (configurable?) background color).  Duping to that instead.

Sorry, I intended bug 713230.

I'm sorry, I was mislead by an image linked that ended in _svg.png
SVG files are thankfully working as intended.
