C++ (Cpp) didDecodeProperties Examples

Example #1

File: BitmapImage.cpp Project: 3163504123/phantomjs

bool BitmapImage::isSizeAvailable()
{
    if (m_sizeAvailable)
        return true;

    m_sizeAvailable = m_source.isSizeAvailable();
    didDecodeProperties();

    return m_sizeAvailable;
}

Example #2

File: BitmapImage.cpp Project: 3163504123/phantomjs

void BitmapImage::updateSize() const
{
    if (!m_sizeAvailable || m_haveSize)
        return;

    m_size = m_source.size();
    m_sizeRespectingOrientation = m_source.size(RespectImageOrientation);
    m_haveSize = true;
    didDecodeProperties();
}

Example #3

size_t BitmapImage::frameCount()
{
    if (!m_haveFrameCount) {
        m_frameCount = m_source.frameCount();
        // If decoder is not initialized yet, m_source.frameCount() returns 0.
        if (m_frameCount) {
            didDecodeProperties();
            m_haveFrameCount = true;
        }
    }
    return m_frameCount;
}

Example #4

File: ImageFrameCache.cpp Project: caiolima/webkit

bool ImageFrameCache::isSizeAvailable()
{
    if (m_isSizeAvailable)
        return m_isSizeAvailable.value();
    
    if (!isDecoderAvailable() || !m_decoder->isSizeAvailable())
        return false;
    
    m_isSizeAvailable = true;
    didDecodeProperties(m_decoder->bytesDecodedToDetermineProperties());
    return true;
}

Example #5

int BitmapImage::repetitionCount(bool imageKnownToBeComplete)
{
    if ((m_repetitionCountStatus == Unknown) || ((m_repetitionCountStatus == Uncertain) && imageKnownToBeComplete)) {
        // Snag the repetition count.  If |imageKnownToBeComplete| is false, the
        // repetition count may not be accurate yet for GIFs; in this case the
        // decoder will default to cAnimationLoopOnce, and we'll try and read
        // the count again once the whole image is decoded.
        m_repetitionCount = m_source.repetitionCount();
        didDecodeProperties();
        m_repetitionCountStatus = (imageKnownToBeComplete || m_repetitionCount == cAnimationNone) ? Certain : Uncertain;
    }
    return m_repetitionCount;
}

Example #6

File: ImageFrameCache.cpp Project: caiolima/webkit

T ImageFrameCache::metadata(const T& defaultValue, std::optional<T>* cachedValue)
{
    if (cachedValue && *cachedValue)
        return cachedValue->value();

    if (!isDecoderAvailable() || !m_decoder->isSizeAvailable())
        return defaultValue;

    if (!cachedValue)
        return (m_decoder->*functor)();

    *cachedValue = (m_decoder->*functor)();
    didDecodeProperties(m_decoder->bytesDecodedToDetermineProperties());
    return cachedValue->value();
}

Example #7

File: BitmapImage.cpp Project: kamihouse/webkit

void BitmapImage::updateSize(ImageOrientationDescription description) const
{
    if (!m_sizeAvailable || m_haveSize)
        return;

    m_size = m_source.size(description);

    m_shouldRespectImageOrientation = static_cast<unsigned>(description.respectImageOrientation());

    m_haveSize = true;

    determineMinimumSubsamplingLevel();
    didDecodeProperties();
}

Example #8

bool BitmapImage::getHotSpot(IntPoint& hotSpot) const
{
    bool result = m_source.getHotSpot(hotSpot);
    didDecodeProperties();
    return result;
}

Example #9

File: BitmapImage.cpp Project: lokifist/webkit

{
    auto result = m_source.hotSpot();
    didDecodeProperties();
    return result;
