Summary: LayerUtility.importPageAsForm distorts rotated pages
Key: PDFBOX-5142
URL: https://issues.apache.org/jira/browse/PDFBOX-5142
Project: PDFBox
Issue Type: Bug
Affects Versions: 2.0.23
Reporter: Eli Zupke
Attachments: out.pdf
The {{LayerUtility}} function {{importPageAsForm}} does not work correctly when
the imported page has a rotation of 90 or 270. The function changes the
dimensions of the rotated page such that it keeps the original, unrotated
aspect ratio, resulting in the content of the page being stretched out.
The following code demonstrates this problem, and the resulting file is
included as an attachment to this issue.
