Andreas Schlegel created FOP-3179:
-------------------------------------
Summary: bounding box on image is not where it should be (PDF/UA)
Key: FOP-3179
URL: https://issues.apache.org/jira/browse/FOP-3179
Project: FOP
Issue Type: Bug
Components: image/unqualified
Affects Versions: 2.9
Environment: Windows 10
Reporter: Andreas Schlegel
Attachments: example.pdf, notice.xml, notice.xsl
Our code generates a PDF file with image and bounding box. But the image and
bounding box are not on top of each other (see attached example.pdf and open it
with axesPDF ).
If the bounding box is missing, the image cannot be displayed at all or not
correctly in alternative representations.
If you use the axesPDF tool
(https://www.axes4.com/de/software-services/axespdf/download), you can see that
the bounding box is always placed in the bottom left corner of the respective
page.
PAC3 doesn't show any error except white spaces instead of images (screenreader
preview) but this is not classified as error.
