PocketMatrix

I wanted to use DrawLine to draw lines between vertices in my simple polygons. However, the polygons may be partly offscreen.

I thought that they would just clip off screen. However, I find that if either end point of the line is off screen, the line does not draw at all.

How can I get clipping behaviour?

Don't worry, I know how to clip a line like I want, I have the Foley graphics book right beside me.

I just want to know if the library provides this functionality before I write my own line drawing functions that clip.

Hi,

GapiDraw does not clip anything. You have to this manually. This is by design and will not change in future versions of the library.
