Inkscape Save Problem

Be aware, though, that an indexed PNG with transparency will tend to have rougher edges because it's more difficult to anti-alias (smooth away the "jaggies") with fewer colors. If you need good crisp edges for a stamp, you're usually best off sticking with a 24-bit PNG.

Just tried it out (thought PNG had only transparency support for 24-bit), and it seems like it can only support one transparent colour (so there's no alpha-channelled colours). Wonder why... I mean, adding alpha-channel support in a palette would only marginally increase file-sizes (that's what like, 255 bytes, 0.25 kbytes per file).

But an indexed file doesn't use channels at all. PNG-8 can actually support more than one transparent color, but not translucency. It depends on your software whether or not you can designate more than one transparent color, though.

Ico: There are actually four versions of PNG, but all that's important to know is that 8-bit PNG is smaller, but it doesn't do angled and round boundaries well. If your stamps are square, 8-bit is fine. If not, use 24-bit.

I meant in the colour definitions, where they have to use channels to define the palette. You might as well add translucency at this point.

Ah, I get it. Interesting idea.
