can fontdue rasterize with fractional pixel offsets?

[wtholliday]

I don't see anything in the API, but perhaps I'm missing it?

I don't need RGB subpixel AA (and indeed I don't think it would work well with my glyph atlas approach, especially when text is transformed), but it would be nice to rasterize with subpixel offsets.

I'm using fontdue in this library which is used in my little GUI library

It's not exposed. There are internals for it, but I haven't put much thought into designing the API. We're already up to 6 rasterize functions and I feel like it's getting out of hand. It honestly might make more sense to make a breaking version change and use a builder style for the various glyph parameters (and potentially future ones), but I'm not sure.

That 3rd parameter set to 0.0 is actually the horizontal offset.

@mooman219 Builder sounds good. Let me know if I can help out!

Following up on this, was there any progress made on this?

I'd be happy to help submit a PR for this if we can settle on an API that folks feel good about.

@mooman219 Ping on this, would you be open to accepting a PR to add support for this?

[mooman219]

Yeah feel free to play around with ideas and send a PR. If you want to explore what a builder might look like I'm open to that, otherwise we can take the easy way out with some more function bloat and expose the offset parameters in yet another function. Given the surface of fontdue is just a couple functions in Font, it's really not so bad.
