While hacking in an application I got a segfault from
XRenderCompositeDoublePoly in libXrender-0.9.2.
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1215826256 (LWP 28888)]
0xb7a1bf60 in XRenderCompositeDoublePoly ()
from /usr/lib/libXrender.so.1 (gdb) bt
#0 0xb7a1bf60 in XRenderCompositeDoublePoly ()
from /usr/lib/libXrender.so.1 #1 0xb7c19ee6 in _xre_poly_draw ()
The problem was a specific set of points added to the polygon as test:
(11, -50), (-10, 30), (-10, -50), (15, 120)
I think the function should never segfault, even if I add a maybe
BTW: Is there a graphic primitive to draw an (filled) arc or circle
with Xrender? Or do I have to implement my own circle algorithm?
Is there an documentation, beside source, about the xorg and in special
More information about the xorg
