From d9f5115eb7f7ba78db245ff9e66ae638317f5b70 Mon Sep 17 00:00:00 2001 From: Andreas Kling Date: Sun, 12 Sep 2010 19:19:52 +0200 Subject: QStroker: Fix erroneous SvgMiterJoin behavior for parallel lines QLineF::intersect() yields an undefined intersectionPoint for parallel lines. Thus if the distance to 0,0 is shorter than the current miter limit, we would draw a triangle to 0,0. Handle this by not drawing the triangle for parallel lines. This matches the behavior of Qt::MiterJoin. --- src/gui/painting/qstroker.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/gui/painting/qstroker.cpp b/src/gui/painting/qstroker.cpp index eabbd8a..9cff339 100644 --- a/src/gui/painting/qstroker.cpp +++ b/src/gui/painting/qstroker.cpp @@ -609,7 +609,7 @@ void QStroker::joinPoints(qfixed focal_x, qfixed focal_y, const QLineF &nextLine } QLineF miterLine(QPointF(qt_fixed_to_real(focal_x), qt_fixed_to_real(focal_y)), isect); - if (miterLine.length() > qt_fixed_to_real(m_strokeWidth * m_miterLimit) / 2) { + if (type == QLineF::NoIntersection || miterLine.length() > qt_fixed_to_real(m_strokeWidth * m_miterLimit) / 2) { emitLineTo(qt_real_to_fixed(nextLine.x1()), qt_real_to_fixed(nextLine.y1())); } else { -- cgit v0.12
