I am using the perl-binding for Cairo.<br><br>For some special use-case of the application (PNG used in a PDF generator) I need PNG's with transparency in the PNG24-format (or PNG-8?), not in the RGBA format (no transparancy in the alpha channels, but a single transparent color). Can anyone point me in the right direction for solving this? My PNG24 surface ends up with an all black background instead of a transparent one.<br> <br>Thanks,<br><br>Marijn<br><font color="#888888"> <div> </div> <br> -- <div>Be Yourself @ <a href="http://mail.com" target="_blank">mail.com</a> <br> Choose From 200+ Email Addresses<br> Get a <b>Free</b> Account at <a href="http://www.mail.com" target="_blank">www.mail.com</a>!</div> </font><br>_______________________________________________<br> cairo mailing list<br> <a href="mailto:cairo@cairographics.org">cairo@cairographics.org</a><br> <a href="http://lists.cairographics.org/mailman/listinfo/cairo" target="_blank">http://lists.cairographics.org/mailman/listinfo/cairo</a><br></blockquote></div><br>
