Implementating Transparent PNGs in IE7

Posted by timothy on from the hammers-and-tongs dept.

Brandon writes "Over at the official IE Blog, Sam Fortiner has posted some very detailed information regarding Alpha PNG Rendering in IE7. From the article: 'As the dev who implemented the support, I can state that it was neither a bug-fix nor did it require a re-write of the display engine. Instead, it ended up being somewhere in-between the two and required what I would call "feature work." Implementing transparency support for PNG images required a significant amount of modification to the image decoding and display pipeline in IE along with a significant amount of new functionality added to the PNG decoder.'"

    This is a really interesting case study in monopoly behavior and the value of competition. Microsoft you will remember pretty much stopped IE development and shut down the IE team.

    Firefox came along, and whamo, all of a sudden Microsoft has developers writing things like. Very impressive. What's interesting for me is they are huge huge company by comparision to Firefox, but it took firefox to really get them to start making some improvements.
