PNG: mainly alpha channel. Basically a "fourth" colour carrying transparency information (in PNG with the same resolution as the other three colour channels, what means that the image can be more-or-less transparent at each pixel). SVG: scaling. You don't have to support one set of icons for each resolution. That said, I haven't managed to like the SVG icons offered by the usual desktop environments. I use PNGs whenever possible :-/ > Does Emacs do scaling of toolbar icons? > If so, when, and why is it important? Since screen resolutions and user preferences vary quite a bit, there is a need to support different "sized" (meaning the pixel size) icon sets. Or just provide scalable icons and let the rendering engine do that dynamically. [...] > I don't understand this -- what are "alpha channels"?
