Redmine

Hello,

in my Wiki pages there are some Text highlighting in format "%{background:yellow}Yellow Background%" as described in RedmineTextFormattingTextile.
All seems to work perfect but not for PDF export.
The PDF isn't colored. The wiki page itself ist colored.

Is there a trick to export colored output or is it a limitation of the export process?
BTW: the same behavior is by exporting RedmineTextFormattingTextile as PDF. Text color ist colored but not for background-color.

Regards,
