Rich text: Add methods for getting string width/height, limiting text to a box/to certain num of chars #27

Open WiIIiam278 opened 5 months ago

I'd like to draw text using rich text's quad drawing mode within a specific box region on a screen (ideally, wrapping the text if it goes over). With the monospace NE_Text.h API I could do NE_TextPrintBox/NE_TextPrintBoxFree to do this, or implement my own thing using NE_TextPrintFree since characters were of a constant known width.

Since rich text is VWF and box drawing isn't a thing in NE_RichText, this isn't quite possible. It'd be great to expose a method to get the length of a string, as DSF exposes DSF_StringRenderDryRun for this purpose, but the handle needed to call DSF methods is abstracted away by Nitro-Engine :).

Similarly, an option to limit the number of characters to draw is no longer present (though of course this isn't a big deal as you can just trim the string before passing it). Still, it'd be nice to have this option.

Hi, thanks for the suggestions!

Regarding the idea of rendering to a text box is okay, but the problem is determining where to cut the text. The monospaced functions just cut it whenever, but that is a pretty bad idea with VWF, I'd say...

For now, I've exposed DSF_StringRenderDryRun in https://github.com/AntonioND/nitro-engine/commit/5ce71a9b02e74defa557ba5dc0f2f5244723f799 so that at least there is that option (I forgot to do it when I added the other functions!).
