Subject: MetaPost graphics with TRT direction
Date: Wed, 25 Mar 2009 17:28:51 +0200 [thread overview]
Message-ID: <20090325152851.GA18337@khaled-laptop> (raw)
[-- Attachment #1.1.1: Type: text/plain, Size: 613 bytes --]
MPost graphics inside TRT direction are placed incorrectly overlapping
the text on the right, similar to what we had with \pdfximage (see the
attached PDF).
This seems to be unrelated to images issue since MPost graphics are
inserted as \pdfliteral. I'm not sure if this an engine or macro issue,
but I'm guessing the later.
Changing the \startMPLIBtoPDF so that the \hbox where the graphics is
placed is fixed to TLT direction fixes this, but I'm not sure if it is
safe to do so.
Regards,
Khaled
