Hello list, I was trying to use the Math Times Pro 2 fonts in ConTeXt MKIV. This Type1 font contains a map file, a set of pfb files and the corresponding tfm files. I was managed to write a .lfg file and a type-imp-xxx file, but here's my problem. The font comes with three different sizes, the virtual fonts in my .lfg file look like: =================================================================== virtuals = { ["mtpro06a-regular"] = { { name = "file:texgyretermes-regular.otf", features = "virtualmath", main = true }, { name = "mt2mif.tfm", vector = "mtpro2-mi", skewchar=0x7F }, { name = "mt2syf.tfm", vector = "mtpro2-sy", skewchar=0x30, parameters = true }, { name = "mt2mbf.tfm", vector = "mtpro2-mb", skewchar=0x7F }, { name = "mt2syaf.tfm", vector = "mtpro2-sya", skewchar=0x7F }, { name = "mt2bbf.tfm", vector = "mtpro2-bb", skewchar=0x7F }, { name = "mt2msf.tfm", vector = "mtpro2-mca", skewchar=0x7F }, { name = "mt2bmsf.tfm", vector = "mtpro2-bmca", skewchar=0x7F }, { name = "mt2mff.tfm", vector = "mtpro2-mfa", skewchar=0x7F }, { name = "mt2bmff.tfm", vector = "mtpro2-bmfa", skewchar=0x7F }, { name = "mt2bbif.tfm", vector = "mtpro2-bbi", skewchar=0x7F }, }, ["mtpro08a-regular"] = { { name = "file:texgyretermes-regular.otf", features = "virtualmath", main = true }, { name = "mt2mis.tfm", vector = "mtpro2-mi", skewchar=0x7F }, { name = "mt2sys.tfm", vector = "mtpro2-sy", skewchar=0x30, parameters = true }, { name = "mt2mbs.tfm", vector = "mtpro2-mb", skewchar=0x7F }, { name = "mt2syas.tfm", vector = "mtpro2-sya", skewchar=0x7F }, { name = "mt2bbs.tfm", vector = "mtpro2-bb", skewchar=0x7F }, { name = "mt2mss.tfm", vector = "mtpro2-mca", skewchar=0x7F }, { name = "mt2bmss.tfm", vector = "mtpro2-bmca", skewchar=0x7F }, { name = "mt2mfs.tfm", vector = "mtpro2-mfa", skewchar=0x7F }, { name = "mt2bmfs.tfm", vector = "mtpro2-bmfa", skewchar=0x7F }, { name = "mt2bbis.tfm", vector = "mtpro2-bbi", skewchar=0x7F }, }, ["mtpro10a-regular"] = { { name = "file:texgyretermes-regular.otf", features = "virtualmath", main = true }, { name = "mt2mit.tfm", vector = "mtpro2-mi", skewchar=0x7F }, { name = "mt2syt.tfm", vector = "mtpro2-sy", skewchar=0x30, parameters = true }, { name = "mt2mbt.tfm", vector = "mtpro2-mb", skewchar=0x7F }, { name = "mt2syat.tfm", vector = "mtpro2-sya", skewchar=0x7F }, { name = "mt2bbt.tfm", vector = "mtpro2-bb", skewchar=0x7F }, { name = "mt2mst.tfm", vector = "mtpro2-mca", skewchar=0x7F }, { name = "mt2bmst.tfm", vector = "mtpro2-bmca", skewchar=0x7F }, { name = "mt2mft.tfm", vector = "mtpro2-mfa", skewchar=0x7F }, { name = "mt2bmft.tfm", vector = "mtpro2-bmfa", skewchar=0x7F }, { name = "mt2bbit.tfm", vector = "mtpro2-bbi", skewchar=0x7F }, }, =================================================================== I guess the suffixes "f" "s" and "t" may correspond to "five" "seven" and "ten", but that's not important. I could use one of them as the virtual font in the typescript: =================================================================== \definefontsynonym [\s!MathRoman] [MTPro10a-Regular@mtpro10a-regular] =================================================================== The output pdf used the 10-size font as expected. I stole some codes from lm.lfg and added the following code: =================================================================== designsizes = { ["MathTimeProA-Regular"] = { ["4pt"] = "MTPro06a-Regular@mtpro06a-regular", ["5pt"] = "MTPro06a-Regular@mtpro06a-regular", ["6pt"] = "MTPro06a-Regular@mtpro06a-regular", ["7pt"] = "MTPro08a-Regular@mtpro08a-regular", ["8pt"] = "MTPro08a-Regular@mtpro08a-regular", ["9pt"] = "MTPro08a-Regular@mtpro08a-regular", ["10pt"] = "MTPro10a-Regular@mtpro10a-regular", ["11pt"] = "MTPro10a-Regular@mtpro10a-regular", ["12pt"] = "MTPro10a-Regular@mtpro10a-regular", default = "MTPro10a-Regular@mtpro10a-regular" }, =================================================================== and modified the typescript: =================================================================== \definefontsynonym [\s!MathRoman] [\v!name:MathTimeProA-Regular] [\s!goodies=math-times-pro-math] =================================================================== It failed as expected: =================================================================== fonts > defining > start stage one: MathRoman mo 1 fonts > defining > specification 'MathRoman mo 1', lookup 'file', name 'MathRoman', sub '', method '', detail '' fonts > defining > stop stage one fonts > defining > start stage two: name:MathTimeProA-Regular (size 393216) fonts > names > font with name 'mathtimeproaregular' cannot be found fonts > names > font database has matching configuration and file hashes fonts > defining > trying (reader sequence driven) type 'otf' for 'MathTimeProA-Regular' with file '' fonts > names > font database has matching configuration and file hashes fonts > defining > trying (reader sequence driven) type 'ttf' for 'MathTimeProA-Regular' with file '' fonts > names > font database has matching configuration and file hashes fonts > defining > trying (reader sequence driven) type 'afm' for 'MathTimeProA-Regular' with file '' fonts > names > font database has matching configuration and file hashes fonts > names > font database has matching configuration and file hashes fonts > defining > loading tfm with name 'MathTimeProA-Regular' fails fonts > defining > trying (reader sequence driven) type 'tfm' for 'MathTimeProA-Regular' with file '' fonts > names > font database has matching configuration and file hashes fonts > defining > loading tfm with name 'MathTimeProA-Regular' fails fonts > defining > trying (reader sequence driven) type 'lua' for 'MathTimeProA-Regular' with file '' fonts > lua loading > using lua reader for 'MathRoman mo 1' fonts > defining > font with asked name 'MathTimeProA-Regular' is not found using lookup 'name' fonts > defining > not loaded and hashed: mathtimeproa-regular @ normal:goodies=math-times-pro-math @ 393216 fonts > defining > unknown font 'MathTimeProA-Regular', loading aborted fonts > defining > unable to define 'MathTimeProA-Regular' as 'math-times-pro-11pt-mm-mr--3' fonts > defining > memory usage after: 45 MB (ctx: 45 MB) fonts > defining > stop stage two =================================================================== I get it. There's no MathTimeProA-Regular file. I've tried the built-in "ebgaramond" typescript which also comes with the "designsizes" field. Interesting, the "ebgaramond-regular" is remapped to "EBGaramond12-Regular" magically: =================================================================== fonts > defining > start stage two: file:ebgaramond-regular (size 720896) fonts > defining > remapping name 'ebgaramond-regular', specification 'auto', size 720896, designsize 'file:EBGaramond12-Regular' =================================================================== Well, what am I missing? How to get the designsize names recognized? What is the right way to make the virtual fonts? Thanks for noticing. Best regards, Zhichu
