Hi I just tried this with a transparent png image on OO.o 1.1.3 on Sarge. The resulting PDF had correct transparency information. If this is still a bug for someone, please speak up. Otherwise I'll close this in a few days. PS Transparent PDFs render very badly on most viewers (XPDF etc). The only one who gets it consistently right is unfortunately Acrobat Reader. :( -- Jussi Pakkanen
