Boris,
Thank you.
I tried and comment out the notification in the OnStartContainer(). I
see the cnn main story image, cnn logo image do not get repaint.
But there are still images get repaint. Can you please tell what are
the other notifications to repaint image?
NS_IMETHODIMP
nsImageLoadingContent::OnStartContainer(imgIRequest* aRequest,
imgIContainer* aContainer)
{
// Do not paint cnn main images
// LOOP_OVER_OBSERVERS(OnStartContainer(aRequest, aContainer));
return NS_OK;
}
NS_IMETHODIMP
nsImageLoadingContent::OnStartFrame(imgIRequest* aRequest,
gfxIImageFrame* aFrame)
{
// LOOP_OVER_OBSERVERS(OnStartFrame(aRequest, aFrame));
return NS_OK;
}
Thank you.
