C++ (Cpp) eval_quad Examples

Example #1

File: SkGeometry.cpp Project: AOSP-JF-MM/platform_external_skia

void SkEvalQuadAt(const SkPoint src[3], SkScalar t, SkPoint* pt, SkVector* tangent)
{
    SkASSERT(src);
    SkASSERT(t >= 0 && t <= SK_Scalar1);

    if (pt)
        pt->set(eval_quad(&src[0].fX, t), eval_quad(&src[0].fY, t));
    if (tangent)
        tangent->set(eval_quad_derivative(&src[0].fX, t),
                     eval_quad_derivative(&src[0].fY, t));
}

Example #2

File: SkGeometry.cpp Project: Crawping/chromium_extract

void SkEvalQuadAt(const SkPoint src[3], SkScalar t, SkPoint* pt, SkVector* tangent) {
    SkASSERT(src);
    SkASSERT(t >= 0 && t <= SK_Scalar1);

    if (pt) {
        pt->set(eval_quad(&src[0].fX, t), eval_quad(&src[0].fY, t));
    }
    if (tangent) {
        *tangent = SkEvalQuadTangentAt(src, t);
    }
