C++ (Cpp) FrameView::pageZoomFactor Examples

Example #1

File: ImageDocument.cpp Project: mikedougherty/webkit

bool ImageDocument::imageFitsInWindow() const
{
    if (!m_imageElement)
        return true;

    FrameView* view = frame()->view();

    IntSize imageSize = m_imageElement->cachedImage()->imageSize(view->pageZoomFactor());
    IntSize windowSize = IntSize(view->width(), view->height());

    return imageSize.width() <= windowSize.width() && imageSize.height() <= windowSize.height();
}

Example #2

File: MouseRelatedEvent.cpp Project: mikedougherty/webkit

static int contentsY(AbstractView* abstractView)
{
    if (!abstractView)
        return 0;
    Frame* frame = abstractView->frame();
    if (!frame)
        return 0;
    FrameView* frameView = frame->view();
    if (!frameView)
        return 0;
    return frameView->scrollY() / frameView->pageZoomFactor();
}

Example #3

File: MouseRelatedEvent.cpp Project: mikedougherty/webkit

static float pageZoomFactor(UIEvent* event)
{
    DOMWindow* window = event->view();
    if (!window)
        return 1;
    Frame* frame = window->frame();
    if (!frame)
        return 1;
    FrameView* view = frame->view();
    if (!view)
        return 1;
    return view->pageZoomFactor();
}

Example #4

File: ImageDocument.cpp Project: mikedougherty/webkit

float ImageDocument::scale() const
{
    if (!m_imageElement)
        return 1.0f;

    FrameView* view = frame()->view();
    if (!view)
        return 1;

    IntSize imageSize = m_imageElement->cachedImage()->imageSize(view->pageZoomFactor());
    IntSize windowSize = IntSize(view->width(), view->height());

    float widthScale = (float)windowSize.width() / imageSize.width();
    float heightScale = (float)windowSize.height() / imageSize.height();

    return min(widthScale, heightScale);
}

Example #5

File: ImageDocument.cpp Project: mikedougherty/webkit

static float pageZoomFactor(Document* document)
{
    FrameView* view = document->view();
    return view ? view->pageZoomFactor() : 1;
}
