Archivo: ImageFrameGeneratorTest.cpp Proyecto: halton/blink-crosswalk

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));
