C++ (Cpp) sk_sp::getPosTan Examples

Example #1

static void test_90_degrees(sk_sp<SkContourMeasure> cm, SkScalar radius,
                            skiatest::Reporter* reporter) {
    SkPoint pos;
    SkVector tan;
    SkScalar distance = cm->length() / 4;
    bool success = cm->getPosTan(distance, &pos, &tan);

    REPORTER_ASSERT(reporter, success);
    REPORTER_ASSERT(reporter, SkScalarNearlyEqual(pos.fX, 0));
    REPORTER_ASSERT(reporter, SkScalarNearlyEqual(pos.fY, radius));
    REPORTER_ASSERT(reporter, SkScalarNearlyEqual(tan.fX, -1));
    REPORTER_ASSERT(reporter, SkScalarNearlyEqual(tan.fY, 0));
