[jira] [Updated] (PDFBOX-4029) Rendering
[ https://issues.apache.org/jira/browse/PDFBOX-4029?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
savan patel updated PDFBOX-4029:
--------------------------------
Description:
i have gone through the "[PDFBOX-3000] Transparency Group issues"...
and there are some issues in pdfs that i have attached...
Every time showTransparencyGroup() method is called the current graphics is translated by (x*xScale and y*yScale) which i assume is wrong.
I think when transparencyGroup come in pattern stream, then current graphics should not changed. as well as when patterns are nested then no need to change the parent graphics.
i tried to fix it. i have attached the patch...
