Hi

I'm looking to add loadble fonts into my terminal, but unsure what format the font is in. I mean, I see it's in base64 format, but not sure what format it is when it is decoded?

Also last night while I was adding sixel support, I think I spotted an error (or at least it confused me) in cterm.txt

Under raster attributes, it says "p3 and p4 define the height and width in sixels" I think it should read "p3 and p4 define the width and height in sixels" as p3 is the width and p4 is the height.

The underlying font format is just bitmap CGA font data, each byte is a row of char/glyph data since the character cells are 8-pixels wide. Fonts can be either 8, 14, or 16 rows high however, so the number of bytes that make up a complete char/glyph depends on the target video mode.

Quite likely just a typo. Something to tell Deuce in irc.synchro.net :-)

Thankyou! I've got it working now :)
