As most of you know, I’m a big fan of the browser Opera, but I use all three of the mainstream browsers (Mozilla and Konqueror fans please don’t yell at me): Netscape 6.2, Microsoft Internet Explorer 6.0 and Opera 5.12. It’s always entertaining to see the differences in how each of them renders the same exact page, especially when a page is valid HTML 4.0.
This one, though, is different. PNG files, although a standard, are handled funny depending on the browser. Like GIF files, they have an optional “interlaced” mode, which is actually implemented much better than the GIF system. When looking at this on the three browsers, something weird happened. First, I discovered that Quicktime had hijacked the MIME type in Netscape.
After getting it set so Netscape loaded PNGs natively, I ended up with two basic PNG handling systems. The Opera and Netscape browsers both rendered the file at “actual size” and so I had to scroll a tiny bit to see the whole image. IE 6, however, seems to have added a cool new image-handling feature: autozoom. When you open an image by itself (not embedded in an HTML file), the browser will shrink it to fit into the window by default. You still have the option of clicking one button and seeing it at full size, but it’s a pretty cool new feature. You know it’s tough for me to compliment Microsoft for something, but there ya go.
Yes, I have too much time on my hands on occasion.
