Module: wine Branch: master Commit: f850488d5a9ab1330bd39491b88997833e2e3efc URL: https://gitlab.winehq.org/wine/wine/-/commit/f850488d5a9ab1330bd39491b889978... Author: Bartosz Kosiorek <gang65(a)poczta.onet.pl> Date: Sat Oct 28 00:26:47 2023 +0200 gdiplus: Move main Curve implementation from GdipAddPathCurve2 to GdipAddPathCurve3. Moving main curve implementation from GdipAddPathCurve2 to GdipAddPathCurve3, allow for use offset and nseg variables in GdipAddPathCurve3. --- dlls/gdiplus/graphicspath.c | 89 +++++++++++++++++++-------------------------- 1 file changed, 38 insertions(+), 51 deletions(-) diff --git a/dlls/gdiplus/graphicspath.c b/dlls/gdiplus/graphicspath.c index 74fdfa6cf45..b65d574e73b 100644 --- a/dlls/gdiplus/graphicspath.c +++ b/dlls/gdiplus/graphicspath.c @@ -534,33 +534,26 @@ GpStatus WINGDIPAPI GdipAddPathCurve(GpPath *path, GDIPCONST GpPointF *points, I { TRACE("(%p, %p, %d)\n", path, points, count);
