Hi,
I encountered an interesting problem with pdf/a-1b checking: if a pdf (produced by pdftex) contains a glyph with zero width (for example, /mapsto from blsy/mtsy), then pdf/a-1b preflight by Acrobat8 gives warnings about incomplete/inconsistent width info. From the technical view, the pdf file seems to be ok: the glyph width in the fontinfo dict is 0 (read from mtsy.tfm), and from the font program:
,-------- | /mapsto { | 56 0 hsbw | ... `--------
So the reason seems that when Acrobat sees a zero glyph width, it treates that width as "missing". Does anyone have some similar experience with this?
in general preflighting documents with math fonts (which show up nicely on the screen and where no system fonts are used i.e. we're not in some fall back mode) is kind of problematic and lots of missing glyphs are reported; unfortunately the file then becomes corrupted when written to disk (acrobat repair mode) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
