Convert font to its vector representation...

[C.M. Rouleau Member Find all posts View Profile Close C.M. Rouleau]

Hello,

I'm very close to finishing a dxf to g-code converter, and was wondering if it might be possible to include text in the conversion as well. I suppose one could do the conversion in the cad app itself, but it seems much more elegant to have my app do it. I suppose the key is to get at the vector representation of a particular font, but I'm sure this is no easy feat. I've taken a look at the FreeType library, but boy, it's seems there's huge mountain to climb there in terms of what functions are really required to do what I want. Anyone have any advise on FreeType or another way of attacking the problem?

CM,

I looked into fonts fairly intently 3 yrs ago, I wanted to see if I could use the technology to create a custom scalable font for displaying antialiased drawings for the web, I quickly realized how much work had already been done with the truetype formats, I suggest "why reinvent the wheel"?, I doubt anyone could improve on the algo's much reguardless of how many hours were thrown at it

Brad,

Perhaps I posed my question incorrectly, but I'm certainly not suggesting I want to reinvent the wheel. Instead, given a truetype font, for instance, what I'm asking is how might one get at its outline - i.e., the lines and curves that make of the font perimeter in the first place.

ok, there are some good web pages out there, I'll try to find, and the best book I've found for details is,

I remember using GetGlyphOutline many years ago to do what you are after.

Hmmm...GetGlyphOutline...right there under my nose in the windows API. Now I suppose it's just a matter of learning to select a TrueType font into a specified device context, and then I *might* be of and running. Is selecting a font into a device context similar to selecting a bitmap into a device context?

The short answer is yes.

hFontOld = SelectObject(hDC, hFont)

' Do stuff here

SelectObject hDC, hFontOld

' hDC = screen|memory|printer device context
