Re: [dev-context] [Fwd: Re: Debian Context Font problems]
Hi Norbert! Thank you very much -- this is perhaps the best bug report i've ever got. :-) It seems, however, that -- as Taco suggested:
This looks suspiciously like a bug (aka optimization) in kpdf.
The glyphs (in lmsy5, lmsy6, lmsy7, lmsy8, lmsy9, and lmsy10) are built properly, the relevant hinting scheme in all cases is trivial (no so called hint replacement that sometimes may be a mischief). By the way, does the same effect occur for other sizes of lmsy*? Cheers -- Jacko -- BOP s. c. ul. Bora-Komorowskiego 24, 80-377 Gdansk, Poland tel.

Thanks, I know how bad are bad bug reports, as DD of texlive I have to fight with enough bad ones ;-)

No idea. If some context guy can tell me how to do it? I have *NO*
knowledge at all from ConTeXt. The test document is:
\starttext
\S1
\blank[big]
\S2\crlf\S3
\stoptext
If one tells me how to make it in other font sizes, I will test.
Best wishes
Norbert

Not kpdf. xpdf shows the same problems as kpdf when invoked with "-t1lib no". Looks like lmodern and freetype don't get along.

I can't vouch for all font sizes but I first encountered the problem at 14.7pt and then reproduced it at default font size for the test case. --Mike Bird

Ok, I tried the following:
\setupbodyfont[17pt]
\definedfont[ec-lmr17]
\starttext
\S1
\blank[big]
\S2\crlf\S3
\stoptext
and got a test.pdf with the following pdffonts output:
name type emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
ZASPBF+LMRoman10-Regular Type 1 yes yes yes 7 0
TMBLAG+LMMathSymbols10-Italic Type 1 yes yes no 10 0
CWHICF+LMRoman17-Regular Type 1 yes yes yes 13 0
Then I opened it with
xpdf -t1lib no test.pdf
(it is true that xpdf exhibits the same problems with t1lib turned off)
And now, surprisingly, the problems occur at different resolutions:
400%: good
200%: the \S symbols are too small and to low
125%: good
100%: BAD, the symbols touch each other
50%: as far as I see like 200%
Attached as usual the respective screen shots.
Best wishes
