Yes, it opens up a whole lot of stylistic possibilities when real PNG support is combined with CSS. Using plug-ins doesn't cut it; we need to be able to specify background images using PNG (including the background color - that \is why the background property has both a color and an image url - one is compoisited onthe other when the image has some transparency). > (I could also add gamma correction as an essential feature.) Yes, clearly. Again, this is a natural complement; PNG allows the gamma (and other color details) to be specified so they look the same on different platforms; CSS specifies what the color s mean so they look the same on different platforms. > > When > > the browser makers do get their act together, PNG will be an awe-inspiring > > sight indeed... Yes. The Acorn browser is a good example of this (pity it works on an obscure platform). > I bet the Mozilla Project would be pretty receptive to a) someone checking to > see if they've fixed this They have not, last I checked > and b) let them know about it i they haven't. > http://www.mozilla.org/projects.html I recently updated the PNG test pahges a little; in particular to check that compositing against a CSS-specified background color works correctly. Or more precisely, to show that it does not. These pages should be useful for the Mozilla project, and other browser writers, to check against. The starting page is http://www.w3.org/Graphics/PNG/ And the actual test pages (linked from there) are: http://www.w3.org/Graphics/PNG/Inline-img.html http://www.w3.org/Graphics/PNG/all_seven.html http://www.w3.org/Graphics/PNG/inline-alpha.html http://www.w3.org/Graphics/PNG/inline-alpha-table http://www.w3.org/Graphics/PNG/inline-alpha-table32.html I would be please to hear reports, with screenshots, of browsers that pass the second and subsequent of these test pages. I would also be interested to see pages that combine PNG and CSS in creative ways. -- Chris
