示例1: calc_dash_scaling
static void calc_dash_scaling(SkScalar* parallelScale, SkScalar* perpScale,
const SkMatrix& viewMatrix, const SkPoint pts[2]) {
SkVector vecSrc = pts[1] - pts[0];
SkScalar magSrc = vecSrc.length();
SkScalar invSrc = magSrc ? SkScalarInvert(magSrc) : 0;
vecSrc.scale(invSrc);
SkVector vecSrcPerp;
vecSrc.rotateCW(&vecSrcPerp);
viewMatrix.mapVectors(&vecSrc, 1);
viewMatrix.mapVectors(&vecSrcPerp, 1);
// parallelScale tells how much to scale along the line parallel to the dash line
// perpScale tells how much to scale in the direction perpendicular to the dash line
*parallelScale = vecSrc.length();
*perpScale = vecSrcPerp.length();
}示例2: SquareCapper
static void SquareCapper(SkPath* path, const SkPoint& pivot,
const SkVector& normal, const SkPoint& stop,
SkPath* otherPath)
{
SkVector parallel;
normal.rotateCW(¶llel);
if (otherPath)
{
path->setLastPt(pivot.fX + normal.fX + parallel.fX, pivot.fY + normal.fY + parallel.fY);
path->lineTo(pivot.fX - normal.fX + parallel.fX, pivot.fY - normal.fY + parallel.fY);
}
else
{
