Description

I found a strange, but consistent error with image positioning. See the very simple attached file.

  • when including a single image in a div, it gets properly aligned with the div
  • when including two images in the same div, they get shifted above the div
    Using DomPDF 2.0.3.
    test.zip
    test.pdf

Research direction

Start with the attached test.zip and compare its output with test.pdf to reproduce the positioning difference between one and two images in a div. Then trace the image and block layout handling in DomPDF. Done means multiple images remain correctly aligned within their containing div, with the supplied reproduction no longer showing the upward shift.
