Petr Slaby updated PDFBOX-2104: ------------------------------- Attachment: TransparencyGroups.2.patch > Implement transparency groups > ----------------------------- > > Key: PDFBOX-2104 > URL: https://issues.apache.org/jira/browse/PDFBOX-2104 > Project: PDFBox > Issue Type: Improvement > Components: Rendering > Affects Versions: 2.0.0 > Reporter: Petr Slaby > Assignee: John Hewson > Attachments: 000001_MTEXT_CS6.pdf, TransparencyGroups.1.patch, > TransparencyGroups.2.patch, TransparencyGroups.patch > > > The attached PDF uses transparency groups, blending and soft masks to create > the rounded corners and shades behind images. It appears that these features > are not implemented in PDFBox. An implementation proposal is attached in the > TransparencyGroup.patch. The basic idea is to create a buffered image, draw > the transparency group content onto it and then use the result to produce the > soft mask or draw the image on the original g2d. > Note: I am not the (only) author of the proposed change. It was developed in > our company few years ago in sources based on a 1.7.x version of PDFBox, > mostly by a guy who already left. Over the years, merging of the work done in > PDFBox main stream into our source base has become impossible due to many > refactorings and other deep going changes done. Now we would like to go the > opposite way - where possible - bring the changes and fixes we have done into > PDFBox main stream and start to use it in our installations. -- This message was sent by Atlassian JIRA (v6.2#6252)
