Legacy ImageMagick Discussions Archive

I use HTMLDOC to generate PDFs from HTML files.

The imagemagick "display" command displays them with transparent ('checked') background, for example http://3e.org/private/test.pdf.

Is there anything I can do to prevent this? On the HTMLDOC side, I've tried adding a tiling white background image, specifying white background with CSS, all to no avail.

The PDF displays fine in Acrobat, Evince, Chrome, and every other PDF viewer I've tried - only "display" gets it wrong.

I don't think this is a bug.

Most viewers (including Adobe Acrobat) show transparent as white. IM "display" shows it as chequerboard. Your PDF is mostly transparent.

You could use IM to turn transparent white ... ... so it shows as white in "display", but this will rasterise the text.

Incidentally: we can verify the PDF has a transparent background by using Adobe Reader: Edit, Preferences, Page Display, tick "Show transparency grid". Then Adobe Reader, just like IM Display, shows a chequerboard.
