[jira] [Comment Edited] (PDFBOX-1875) Image and some text missing
in rendered file
[ https://issues.apache.org/jira/browse/PDFBOX-1875?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14044956#comment-14044956 ]

I think that the problem is a missing BBox handling.
The page has two "forms" (not to confused with Acroform, "forms" are streams of PDF operators and stuff). Both have a white rectangle fill at the beginning. I have modified that PDF so that one is filled blue and one green.
When rendered with PDFBox, almost the whole right half of the page is filled, and this explains why there's that white space in the original rendering.
The reason is that the BBox of the "form" is not taken into account. According to the pdf spec, this is a clipping rectangle.
I used [~pslabycz]'s code from createPageDrawerGroup to create a clipping rectangle and it renders nicely now. Committed in rev 1605864 for the trunk.
