Re: Border-image transparency
Thanks very much for the excellent testcase!
I don't think this is an issue with transparency. The PNG transparency seems to be getting rendered just fine. However there are some other issues making it look bad:
1) There seems to be a PIE bug where it still tries to render the solid border even when border-image is specified, whereas it should discard the border. I've opened ticket http://github.com/lojjic/PIE/issues/issue/51
to get that fixed.
2) For your second demo, it is missing the 'fill' keyword to tell it to fill in the center of the border-image like a background. The CSS3 spec requires this keyword, though other browsers don't seem to enforce that yet. PIE follows the spec.
3) On the paragraphs I see the top-right and bottom-right slices are shifted to the right by 1px. This looks like a PIE bug; I've opened ticket http://github.com/lojjic/PIE/issues/issue/52
to track it.
Those are the issues I see. Is there anything else you've found?
