[9fans] draw: bezsplinepts - howto?

[Anthony Sorace]

Anyone have a working example of using draw’s bezsplinepts? I assume I’m doing something wrong here, but evenings are a just iterating over the pointer it sets and trying to print the points with %P is giving me nonsense values.

<sigh> 
…but even just iterating…

Anyway, it’s in the middle of a slightly messy program at the moment; i’m writing a simpler test. But still, an example would be appreciated.

Check out the pdffs code on my exp branch on sr.ht (under ~pixelherodev). I'm using bezierpts to generate polygons for all rendering; bezsplinepts should be equivalent.

(Pdffs can render shapes now btw. Implemented that two weeks ago ;)

Well, my minimal reproducer failed to reproduce my problem. Turns out the typos aren't just limited to email. Did you know "p" and "q" are different letters? Sorry for the noise.

In case anyone's curious, here's the "reproducer", which takes the points from two b-splines and uses them as a polygon to fill the shape out.
