The bug has been opened on https://bugs.launchpad.net/bugs/132417
When displaying a PDF document with a non-embedded font 'ArialMT', no attempt is made to display the ArialMT font.
evince asking fontconfig to produce the closest match to the ArialMT font.
no request for font is seen in debug output of fontconfig.
It might be a poppler issue, poppler seems to convert ArialMT into Helvetica wich receives a less fitting match from fontconfig when Arial is present.
After trying to find an excellent example, i'll have to amend my bugreport a tiny bit. It is not about ArialMT but about non-embedded: PalatinoLinotype-Roman
It's about document http://www.vmware.com/pdf/vi3_301_201_admin_guide.pdf
The 'normal' text on for instance book page 7, is in acrobat reader a serif typeface, in evince it is a 'sans-serif'.
When i turn on FC_DEBUG=4 and 'printCommands yes' i learn the following:
Add Subst match
pattern any family Equal "Palatino-Roman"
Edit family Append "URWPalladioL-Roma";
(indeed: fc-match Palatino-Roman gives: URWPalladioL-Roma.pfb: "URW Palladio L" "Roman", which is in gfonts-x11)
I am not a master in interpreting fontconfig / poppler debug output, but i will try to find the relevant spot:
If poppler encounters the lines:
Tf /TT8 1
font: tag=TT8 name='PalatinoLinotype-Roman' 1
Tm 10.98 0 0 10.98 153 640.02
Tj (Customizing Guest Op)
It starts finding a proper font match.
FcConfigSubstitute Pattern has 6 elts (size 16)
family: "Palatino Linotype"(s)
(it passes the opportunity to match a close relative:)
FcConfigSubstitute test pattern any family Equal "Palatino-Roman"
(and concludes with:)
pattern all family NotEqual "sans-serif"
pattern all family NotEqual "serif"
pattern all family NotEqual "monospace"
Edit family AppendLast "sans-serif";
Does this help you any further?
By the way, i've recompiled libpoppler-glib and removed the internal font face translation (effectively delegating it to fontconfig). And the PDF's look almost perfect."
i wonder how are we supposed to transform PalatinoLinotype-Roman into Palatino-Roman.
why don't you let fontconfig do the job there?
So you are telling me that
works for you?
The submitter comment suggest it makes the document being rendered correctly
then tell the submitter to come here and speak with me :-)
is this still valid? and is it really cairo-backend only? I see the same font with current poppler than acroread.
