[jira] [Comment Edited] (PDFBOX-2217) Matrix transform ignored in axial and radial shadings (in PDFToImage output)

    [ https://issues.apache.org/jira/browse/PDFBOX-2217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14259647#comment-14259647 ]

-------------------------------------------------------------------

I'm currently working on this, and this will be done in two steps:
- apply inverted ctm and xform to each coordinate in getRaster, as I already do with type1 shading (works fine, see attachment) but without the optimizations
- reintroduce the optimizations in the new code

Other files with the same problem:
- PDFBOX-2344-233644-p10.pdf (axial, see "rolling" and "scrap processing")
- PATTYP1.pdf (axial, the "L" shadings must be diagonal)
