ASF subversion and git services commented on PDFBOX-4267: --------------------------------------------------------- Commit 1838362 from til...@apache.org in branch 'pdfbox/trunk' [ https://svn.apache.org/r1838362 ] PDFBOX-4267: convert matte to RGB > Incorrect rendering when /Matte entry > ------------------------------------- > > Key: PDFBOX-4267 > URL: https://issues.apache.org/jira/browse/PDFBOX-4267 > Project: PDFBox > Issue Type: Bug > Components: Rendering > Affects Versions: 2.0.11, 3.0.0 PDFBox > Reporter: Tilman Hausherr > Assignee: Tilman Hausherr > Priority: Major > Fix For: 2.0.12, 3.0.0 PDFBox > > Attachments: bugzilla888437.pdf, gs-bugzilla688797-reduced.pdf, > gs-bugzilla688797.pdf > > > The image softmask in the attached file has a {{/Matte 0 0 0}} entry. PDFBox > displays the PDF differently than Adobe Reader, the reflection shown by > PDFBox is barely visible. When the /Matte entry is deleted, then it is barely > visible in Adobe Reader too. So the /Matte entry does make some difference, > although I don't understand how. > In the PDF specification, the formula shown is c' = m + α x (c - m). So 0 > should have no effect?! > I looked at the code of PDF.js, they have a special handling when alpha is 0, > don't know why. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@pdfbox.apache.org For additional commands, e-mail: dev-h...@pdfbox.apache.org
