TouchGFX, how to draw images in A4 or A8 format?

[Gom]

Hi

It seems that ChromART supports A4 and A8 formats very well, but I haven't found a way to draw dynamic bitmaps that use either of these formats -- it fails on an assert.

Glyphs can use both of them (efficiently), so there must be a way to do it? So far I've hacked a custom Font class that creates a glyph with my custom bitmap data, and a widget that calls LCD::drawGlyph... but that's really silly (and buggy -- see my other post about big glyphs).

Did I miss something? If not, it would be great to support these formats directly. Why is there an assert that prevents from using them?

Thanks.
