Adafruit GFX new font?

[pigman]

Hi,

Is it possible to create/convert a font over to work with the GFX Library?

I'm keen to create another font for the screen.

Cheers

you can, we have no documentation or tutorials on how to create a new font

This thread, as well as picking through the Adafruit_GFX library source, might give some insights for how an alternate font can be implemented.

I've been thinking about making a glyph editor for this font as well.

Have you made any progress, pigman? Anyone else done work in this direction?
If not i'll share what I come up with.

Hey, no haven't made any progress with it as yet. I have been looking at utft lately they have a font creator I think but haven't had time to do much with that either let use all know your progress

Ok, I've got an editor worked up. I did it in Excel to take advantage of some formatting and editing conveniences. It gives a visualization of each glyph from the Adafruit_GFX lib 5x7 font, and lets you edit and get revised output to a custom version of the font file (glcdfont.c).

There are 2 versions in the zip:
GlyphEditor_5x7.xlsx: This is the best one, uses Excel conditional formatting rules for a nicer matrix visualization. May not work in other spreadsheet editing programs.
GlyphEditor_5x7-textonly.xlsx: If the one above just shows ones and zeroes in the matrix viz in your spreadsheeting program, use this one instead. It does not use conditional formatting.

Let me know how it works out for you.

If you are interested in a using of fonts with a variable glyph width (not limited to a matrix like 5x7), try TTF font converter tool of http://pd4ml.com/pixelmeister/ and its uText library.

The resulting fonts are very compact, as they include only requested glyphs (or glyph ranges) and the glyph bitmap data is packed. Optionally the fonts can include antialiasing hints.
