I guess this was asked already at Can I make a greek letter extra-bold in math mode?, but it didn't get the answer I wanted to read, so I'll try again
I'm not interested in bold math here, my situation is this: I like
lmtt teletype font, and the only thing I'd like is to make
lmtt a bit bolder; I know about
[lighttt], but I don't like it so much - and I would not like to change to a different typewriter font just because of this. But this problem could occur in a different context, too, which is why I would like to ask in more generic terms: would it be possible in Latex to "derive" a "bolder" version of a font, by re-"stroking" the letters with a thicker line?
I would guess, out of the box no - but I wanted to confirm that. As far as I can remember, in PDF itself, you declare a font, and a family/size for it, and when you place a text PDF primitive, the letters are simply used to look up the font glyph, which is then placed. As there is no "line width" parameter there (that I can remember) for the font stroke, I doubt Latex could use something like that either.
However, maybe somehow Latex could be used, for each such "artificially" bold letter, to:
- re-draw the letter with a given stroke
- convert the stroke to a filled path
- find the union of the filled path and the path derived from stroke
- insert this vector as a glyph in a new font table exported in the PDF
Not even sure if Latex does these kinds of operations (though I guess Tikz, or LuaLatex, might) - but I think it would be nice to know what are the possibilities for them.
I also just found this:
For actual printing, you could set the MF options and generate new bitmaps to use (as a Type 3 bitmap font), but that's an awkward solution.
So apparently, there is a possibility for a bitmap approach with Metafont - but here I'm interested in a vector approach. I'd be OK with using external programs, too, as long as all work can be initiated by Latex (via
