I'm trying to rewrite an application of mine from core X drawing primitives into Xrender Picture drawing. For this, I need to draw an arc.
I wrote a sample code I posted on pastebin to practice Xrender drawing. I wrote a simple function drawarc() that uses XTriangle's to compose an arc. It is called in main() to draw a 90-degrees white arc. But the drawn arc is not white; it is grayish. That's probably because of the smooth edge attribute of the individual triangles. But I want the arc to be white. Am I using the correct Picture attributes? What is the best way to draw an solid-color arc using XRender? I am really new to Xrender (and to Xlib and compositing in general), so I have no idea what should I do. Here is the code: https://pastebin.com/raw/a6vd1WcL PS: I'm using 1/64 of a degree as angle unit (just as core X does). _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
