Gecko engine does not render vibrant images on the mac

with 6 comments

I was looking at this beautiful image today in Firefox and made it my desktop background, but then I noticed that it looked even better as a background than in the Firefox window. A little more investigating revealed that (at least on mac) Gecko doesn’t render images as vibrant as Safari.

Webkit (Safari) vs. Camino (Mozilla):

Just something to keep in mind next time you’re Flickring.

  1. Nice comparison… but do you know which one is displayed the true colours ? I iknow that IE is displaying pictures 10% brighter than the riginal, firefox seems almost true. But is it really true ?

    Any idea ?

  2. Gecko’s image display doesn’t seem to be fantastic in general; image scaling is also _very_ shoddy.

  3. Oliver, that question is a bit vague. I suppose it depends on many things whether or not the colours are “true”, one of the most important having a good monitor colour profile. In this case, I think that Safari is displaying the “most true” colours as they match most other applications and OSX is probably better than most OSes when it comes to colour anyway, just like fonts. The difference I gave here was amplified when I tried it on a Dell 20″ widescreen.

    Rob, yea totally, it has many issues. I reluctantly still use it however as Safari just doesn’t measure up in a number of areas. Number 1 for me being tab scrolling. Firefox 3 image scaling will actually be performed by Cairo though, so at least that will be better.

  4. Gecko rendering is libpr0n.
    They’re dedicated to rendering pr0n as fast as possible.

    Go take the issue up with them :).
    (And, besides word usage that may raise an eyebrow, and external links to porn sites [I think… never did actually click them], the site is more or less work safe. But practice due diligence, and just don’t bother clicking it at work in the first place.)

  5. Hooray for (likely unintentionally) resyndicated articles!

    Now that I’m back, there’s been a lot of discussion about how the resized versions of photos look on Zooomr (and I’m sure Flickr has their fair share as well).

    I believe the consensus it came too was a lack of color profile (sRGB, etc.) preservation.

  6. The reason for this is well documented. Safari actually uses the Colour Profile from the image and renders it accordingly, all other web browsers just assume that the image has a ‘normal’ colour profile.

    To check, you can download the image and open it in Photoshop and see what the Colour Profile or Colour Space is. If you convert it to sRGB it’ll look the same in all browsers.
