C++ (Cpp) WebFrame::printPagesWithBoundaries Examples

Example #1

void WebViewHost::paintPagesWithBoundaries()
{
    ASSERT(!m_isPainting);
    ASSERT(canvas());
    m_isPainting = true;

    WebSize pageSizeInPixels = webWidget()->size();
    WebFrame* webFrame = webView()->mainFrame();

    int pageCount = webFrame->printBegin(pageSizeInPixels);
    int totalHeight = pageCount * (pageSizeInPixels.height + 1) - 1;

    SkCanvas* testCanvas = skia::TryCreateBitmapCanvas(pageSizeInPixels.width, totalHeight, true);
    if (testCanvas) {
        discardBackingStore();
        m_canvas = adoptPtr(testCanvas);
    } else {
        webFrame->printEnd();
        return;
    }

    webFrame->printPagesWithBoundaries(canvas(), pageSizeInPixels);
    webFrame->printEnd();

    m_isPainting = false;
}
