This is true for most arcs except -for pie-slice arcs strictly between 180 and 360 degrees where the missing -portion of the arc faces up or down such that we get two spans on some -scanlines. - -For those, we need to reserve room for another height/2 spans. This -patch just does it for all partial pie-sliced arcs to make the test -easier to understand; it's just over-allocating a bit of memory, so -that's safe. - -Signed-off-by: Keith Packard <keithp@keithp.com> -Reviewed-by: Adam Jackson <ajax@redhat.com> ---- - mi/mifillarc.c | 5 +++++ - 1 file changed, 5 insertions(+) - -diff --git a/mi/mifillarc.c b/mi/mifillarc.c -index 246d70f..888519e 100644 ---- a/mi/mifillarc.c -+++ b/mi/mifillarc.c -@@ -660,6 +660,11 @@ miPolyFillArc(DrawablePtr pDraw, GCPtr pGC, int narcs_all, xArc * parcs) - if (narcs && nspans + arc->height > MAX_SPANS_PER_LOOP) - break; - nspans += arc->height; -+ -+ /* A pie-slice arc may add another pile of spans */ -+ if (pGC->arcMode == ArcPieSlice && -+ (-FULLCIRCLE < arc->angle2 && arc->angle2 < FULLCIRCLE)) -+ nspans += (arc->height + 1) >> 1; - } - - pts = points = malloc (sizeof (DDXPointRec) * nspans + --- -2.3.5 - |
