We have
$>vftovp txr.vf (VTITLE ) (FAMILY TXR) (FACE F MRR) (CODINGSCHEME TEX TEXT) (DESIGNSIZE R 10.0) (COMMENT DESIGNSIZE IS IN POINTS) (COMMENT OTHER SIZES ARE MULTIPLES OF DESIGNSIZE) (CHECKSUM O 32212676346)
while from luatex source
source/texk/web2c/luatexdir/font/vfovf.w: @ process a local font in \.{VF} file @c static internal_font_number vf_def_font(internal_font_number f, unsigned char *vf_buffer, int *vf_cr) { : unsigned long checksum; cs.b0 = vf_buffer[(*vf_cr)]; cs.b1 = vf_buffer[(*vf_cr) + 1]; cs.b2 = vf_buffer[(*vf_cr) + 2]; cs.b3 = vf_buffer[(*vf_cr) + 3]; (*vf_cr) += 4; checksum = (unsigned) (cs.b0 * 256 * 256 * 256 + cs.b1 * 256 * 256 + cs.b2 * 256 + cs.b3); :
if (checksum != 0 && font_checksum(k) != 0 && checksum != font_checksum(k)) vf_local_font_warning(f, k, "checksum mismatch", (int) checksum, (int) font_checksum(k)); if (ds != font_dsize(k)) vf_local_font_warning(f, k, "design size mismatch", ds, font_dsize(k));
It's not related to MKIV but to luatex, and it's a warning. It doesn't even matter to have --modules==all, this vf file in the standard standalone. Of course you must have the pfb/afm or otf or ttf file, as usual, otherwise the pdf is wrong
I was not sure, that why I began this thread. I started with latex example, then strip it down to plain tex one and after that came to context minimal example. it's also in pdftex: see function vf_def_font in src/texk/web2c/pdftexdir/pdftex.web
AFAIU, context suite doesn't have "plain" pdftex and luatex formats, therefore I compile minimal plain tex example with TeX Live 2011, and luatex doesn't print such message though it reads vf file.
Hm, have a look at tex/texmf-context/tex/generic/context/luatex
The problem indeed may be it luatex and how it works with vf fonts, but as I said, I'm not sure (don't know very well either plain tex or context).
P.S. Unrelated: seems I completely lost, I read web sources, the quoted extract from luatex source and I don't understand how this number '32212676346' can be presented as
cs.b0 * 256 * 256 * 256 + cs.b1 * 256 * 256 + cs.b2 * 256 + cs.b3
If I don't lose my math skills the '32212676346' is 32212676346=7·256^{4}+128·256^{3}+6·256^{2}+110·256^{1}+250·256^{0}
IIRC, 32212676346 should be the checksum stored inside the file, ie the font_checksum. -- luigi
