Hi Patrick, --Original Message--: >Hi folks! > >I'm hoping you can help with a few clarifications. > > ><image>: The Document Structure module states: > >"For a single-channel raster image, the effect is as if the object were converted into a 4-channel RGBA image, where the single channel from the referenced object is used to compute the three color channels and the alpha channel is uniformly set to 1." > >Is it expected that single channel raster images are actually converted in memory to 4 channel, or just that the images can "appear" (have 'the effect'). As long as the result is the same, your in-memory representation doesn't matter. What that is implying is that if you have an RGBA backing store for example and you paint a single-channel PNG or similar that the alpha channel bits will get set. Remember the backing store, or new background when you go: <g enable-background="new">...</g> creates a new transparent black backing store. So if you paint a single channel image into it, you really do want to set the alpha on the pixels that get touched. >Integration: I've been reading on the improvements to the methods by which SVG can be surfaced on the web.

That looks like a really early work in progress. If you want to address integration issues, then I would highly recommend you read this document: http://www.w3.org/TR/WICD/ You should take that document as the definitive guide to integration at the present time.
