Description Ken Harris 2006-01-19 03:48:47 UTC

The docs for cairo_arc() say "An angle of M_PI radians (90 degrees) is in the
direction of the positive Y axis (in user-space)."  But 90 degrees is pi/2
radians, not pi radians.

Comment 1 Carl Worth 2006-01-19 04:43:03 UTC

Fixed in cairo 1.1.1:

2006-01-18  Carl Worth  <cworth@cworth.org>

        * src/cairo.c: Fix documentation of cairo_arc which erroneously
        claimed M_PI radians == 90 degrees to correctly say that M_PI/2.0
        radians == 90 degrees. This closes bug #5649 (with thanks to
        kengruven@gmail.com).
