Just an update.

In a fresh full.sysout, I did (FILESLOAD READ-BDF).

Then I constructed a list of the paths to the 17 .bdf files for assembling a composite NotoSans 72 MRR.

(These correspond to the pieces used for the HTMLSTREAM font assembly, in the same order.)

In the XCL exec, changed the *PACKAGE* to BDF and entered

(PROG1 T

(TIME (SETQ NS72 (BUILD-COMPOSITE NSTESTFILES))))

and waited… and waited… and…

Just short of 20 MINUTES later, it finished:

The files total 111MB.

 

So, now we know that a very large font can be constructed from BDF files.

(And, of course, I found a couple more bugs that I’ll commit and push.)
