示例1: transform
// MakeGradient
Gradient*
SVGRadialGradient::MakeGradient() const
{
//printf("SVGRadialGradient::MakeGradient()\n");
// TODO: handle userSpaceOnUse/objectBoundingBox
Gradient* gradient = new Gradient(true);
gradient->SetType(GRADIENT_CIRCULAR);
gradient->SetInterpolation(INTERPOLATION_LINEAR);
double cx = 0.0;
double cy = 0.0;
double r = 100.0;
BString value;
if (FindString("cx", &value) >= B_OK)
cx = atof(value.String());
if (FindString("cy", &value) >= B_OK)
cy = atof(value.String());
if (FindString("r", &value) >= B_OK)
r = atof(value.String());
// the transformed parallelogram
double parl[6];
parl[0] = cx - r;
parl[1] = cy - r;
parl[2] = cx + r;
parl[3] = cy - r;
parl[4] = cx + r;
