Do you have a minimal test case you can show us? Do you use the windows surface or windows printing surface backend? What version of cairo do you use? Also check you are not using unconstrianed operations like paint without clip.<br> <br>~G<br><br><br><div class="gmail_quote">On Wed, Oct 14, 2009 at 5:14 PM, Liang Wang <span dir="ltr"><<a href="mailto:bluepower1983@yahoo.com">bluepower1983@yahoo.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <table border="0" cellpadding="0" cellspacing="0"><tbody><tr><td style="font-family: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; font-size: inherit; line-height: inherit; font-size-adjust: inherit; font-stretch: inherit;" valign="top"> Hello, I am a software engineer in china. We are developing a new product, but we experiencing a problem. When we use cairo transparency effect to draw graphics on text or graphics drawed by gdi, after printing, we found the effect of transparency is enable. The graphics drawed by cairo will cover the graphic drawed by gdi. But when we use that on a graphic drawed by cairo, after printing, it is correct. So, I wanna know why and how to resolve this problem.<br> <br> I am looking forward to your reply as soon as possible.<br>Thank you very much.<br><br></td></tr></tbody></table><br> <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>
