示例1: test_empty
// Test that all the SkRRect entry points correctly handle un-sorted and
// zero-sized input rects
static void test_empty(skiatest::Reporter* reporter) {
static const SkRect oooRects[] = { // out of order
{ 100, 0, 0, 100 }, // ooo horizontal
{ 0, 100, 100, 0 }, // ooo vertical
{ 100, 100, 0, 0 }, // ooo both
};
static const SkRect emptyRects[] = {
{ 100, 100, 100, 200 }, // empty horizontal
{ 100, 100, 200, 100 }, // empty vertical
{ 100, 100, 100, 100 }, // empty both
{ 0, 0, 0, 0 } // setEmpty-empty
};
static const SkVector radii[4] = { { 0, 1 }, { 2, 3 }, { 4, 5 }, { 6, 7 } };
SkRRect r;
for (size_t i = 0; i < SK_ARRAY_COUNT(oooRects); ++i) {
r.setRect(oooRects[i]);
REPORTER_ASSERT(reporter, !r.isEmpty());
r.setOval(oooRects[i]);
REPORTER_ASSERT(reporter, !r.isEmpty());
r.setRectXY(oooRects[i], 1, 2);
REPORTER_ASSERT(reporter, !r.isEmpty());
r.setNinePatch(oooRects[i], 0, 1, 2, 3);
REPORTER_ASSERT(reporter, !r.isEmpty());
r.setRectRadii(oooRects[i], radii);
REPORTER_ASSERT(reporter, !r.isEmpty());
}
for (size_t i = 0; i < SK_ARRAY_COUNT(emptyRects); ++i) {
r.setRect(emptyRects[i]);
REPORTER_ASSERT(reporter, r.isEmpty());
r.setOval(emptyRects[i]);
REPORTER_ASSERT(reporter, r.isEmpty());
r.setRectXY(emptyRects[i], 1, 2);
REPORTER_ASSERT(reporter, r.isEmpty());
r.setNinePatch(emptyRects[i], 0, 1, 2, 3);
REPORTER_ASSERT(reporter, r.isEmpty());
r.setRectRadii(emptyRects[i], radii);
REPORTER_ASSERT(reporter, r.isEmpty());
}
}示例2: assert_transform_failure
// Called for a matrix that should cause SkRRect::transform to fail.
static void assert_transform_failure(skiatest::Reporter* reporter, const SkRRect& orig,
const SkMatrix& matrix) {
// The test depends on the fact that the original is not empty.
SkASSERT(!orig.isEmpty());
SkRRect dst;
dst.setEmpty();
const SkRRect copyOfDst = dst;
const SkRRect copyOfOrig = orig;
bool success = orig.transform(matrix, &dst);
// This transform should fail.
REPORTER_ASSERT(reporter, !success);
// Since the transform failed, dst should be unchanged.
REPORTER_ASSERT(reporter, copyOfDst == dst);
// original should not be modified.
REPORTER_ASSERT(reporter, copyOfOrig == orig);
REPORTER_ASSERT(reporter, orig != dst);
