[FOP-3171] Certain PNG images (grayscale, transparent) produce broken PDF

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved

Description

Rendering the attached document, which references the also attached image, produces a broken PDF in version 2.8 and 2.9. Depending on the PDF viewer, the image is distorted, or is shown with a large black bar at the bottom, or is shown three times, or is not shown at all. In some viewers, the content following the image is not shown.

Up until version 2.7 the resulting PDF was fine. Generated PDFs are attached.

The image in question was auto-generated by a customer. If this cannot be fixed easily, it may help to know what property of the image causes the problem for finding a workaround.
