示例1: paintCurrentFrameInContext
void WebMediaPlayerClientImpl::paintCurrentFrameInContext(GraphicsContext* context, const IntRect& rect)
{
// Normally GraphicsContext operations do nothing when painting is disabled.
// Since we're accessing platformContext() directly we have to manually
// check.
if (m_webMediaPlayer && !context->paintingDisabled()) {
PlatformGraphicsContext* platformContext = context->platformContext();
WebCanvas* canvas = platformContext->canvas();
m_webMediaPlayer->paint(canvas, rect, platformContext->getNormalizedAlpha());
}
