How do I write my own Glyph Transformer functions?

[outofstepfontco]

I found out that Fontforge has non-linear formula-based transformations, and have started experimenting with applying sine waves to outlines, such as in x=x+20*sin(y*0.05).

FontCreator allows the use of XML to run Glyph Transformer scripts, but the existing functions are limited. How do we write our own Glyph Transformer functions? I can't find any XML files with the functions in the software folders.

Thanks in advance,

One can only use the available commands in the Glyph Transform Dialog to compose scripts.

Glyph Transformer.

There is no way to write one’s own functions to add to the available features.

That's a bit of a bummer.
I'll keep trying FontForge, thanks again
