示例1: setFrameStatus
TEST_F(ImageFrameGeneratorTest, incompleteBitmapCopied)
{
setFrameStatus(ImageFrame::FramePartial);
const ScaledImageFragment* tempImage= m_generator->decodeAndScale(fullSize());
EXPECT_FALSE(tempImage->isComplete());
EXPECT_EQ(1, m_frameBufferRequestCount);
ImageDecoder* tempDecoder = 0;
EXPECT_TRUE(ImageDecodingStore::instance()->lockDecoder(m_generator.get(), fullSize(), &tempDecoder));
ASSERT_TRUE(tempDecoder);
EXPECT_NE(tempDecoder->frameBufferAtIndex(0)->getSkBitmap().getPixels(), tempImage->bitmap().getPixels());
ImageDecodingStore::instance()->unlockCache(m_generator.get(), tempImage);
ImageDecodingStore::instance()->unlockDecoder(m_generator.get(), tempDecoder);
