Re: [NTG-context] kpfonts, math, type 1 font

As for the point: "bold uppercase greek letters aren’t mapped" I've inserted the following at the beginning of file "pkfonts-math.lfg": (I put the whole file it'll be easier to understand) => capital greek are not showing though I've mimicked the file "lucida-typeone-math.lfg". -- file: kpfonts-math.lfg local mathencodings = fonts.encodings.math mathencodings["tex-mrb"] = { [0x1D6AA] = 0x00, -- Gamma [0x1D6AB] = 0x01, -- Delta [0x1D6AF] = 0x02, -- Theta [0x1D6B2] = 0x03, -- Lambda [0x1D6B5] = 0x04, -- Xi [0x1D6B7] = 0x05, -- Pi [0x1D6BA] = 0x06, -- Sigma [0x1D6BC] = 0x07, -- Upsilon [0x1D6BD] = 0x08, -- Phi [0x1D6BF] = 0x09, -- Psi [0x1D6C0] = 0x0A, -- Omega [0x1D6A8] = 0x41, -- Alpha [0x1D6A9] = 0x42, -- Beta -- [0x02145] = 0x44, [0x1D6AC] = 0x45, -- Epsilon [0x1D6AE] = 0x48, -- Eta [0x1D6B0] = 0x49, -- Iota [0x1D6B1] = 0x4B, -- Kappa [0x1D6B3] = 0x4D, -- Mu [0x1D6B4] = 0x4E, -- Nu [0x1D6B6] = 0x4F, -- Omicron [0x1D6B8] = 0x52, -- Rho [0x1D6BB] = 0x54, -- Tau [0x1D6BE] = 0x58, -- Chi [0x1D6AD] = 0x5A, -- Zeta -- [0x00302] = 0x5E, -- [math]hat -- the real math one -- [0x02146] = 0x64, -- [0x02147] = 0x65, -- [0x00303] = 0x7E, -- [math]tilde -- the real one } return { name = "kpfonts-math", version = "1.00", comment = "kpfonts, math part.", author = "Chris", copyright = "ConTeXt development team", mathematics = { mapfiles = { "kpfonts.map", -- "mkiv-base.map", }, virtuals = { ["kpfonts-rm"] = { -- MathRoman { name = "file:jkpmn8a", features = "virtualmath", main = true }, { name = "jkpmia", vector = "tex-mr", skewchar=0x7F }, { name = "jkpmi", vector = "tex-mi", skewchar=0x7F }, { name = "jkpmi", vector = "tex-it", skewchar=0x7F }, { name = "jkpbn8a", vector = "tex-bf", skewchar=0x7F }, { name = "jkpbmi", vector = "tex-bi", skewchar=0x7F }, { name = "jkpsy", vector = "tex-sy", skewchar=0x30, parameters = true }, { name = "jkpex", vector = "tex-ex", extension = true }, { name = "jkpsya", vector = "tex-ma" }, { name = "jkpsyb", vector = "tex-mb" }, }, ["kpfonts-bf"] = { -- MathRomanBold { name = "file:jkpbn8a", features = "virtualmath", main = true }, { name = "jkpbmia", vector = "tex-mrb", skewchar=0x7F }, -- this line modified accordingly { name = "jkpbmi", vector = "tex-mi", skewchar=0x7F }, { name = "jkpbmi", vector = "tex-it", skewchar=0x7F }, { name = "jkpbsy", vector = "tex-sy", skewchar=0x30, parameters = true }, { name = "jkpbex", vector = "tex-ex", extension = true }, { name = "jkpbsya", vector = "tex-ma" }, { name = "jkpbsyb", vector = "tex-mb" }, } } } } On Sat, Jan 11, 2014 at 3:03 PM, Wolfgang Schuster wrote:

The characters are squeezed together because the font has wrong metrics.

If the assumption that "mdugmr7m.tfm" contains the metrics for "md-gmm7m.pfb" is correct, then fontforge show it (mdugmr7m), contains bold characters, which then should show.

When you use a Type 1 math font with ConTeXt MkIV all characters in the different files are mapped to the corresponding unicode points but these mappings aren’t complete (e.g. bold uppercase greek letters aren’t mapped).

For some fonts you would also need a custom mapping because not all fonts put the symbols in the same position.
