Flowdocument's image memory usage exception

[tingjiangcao]

Description

In richtextbox, pasting a lot of images, or embedding custom controls can cause memory spikes. This can be solved if you set the cache mode for images to none. But you can't set it for pasted-in images.

BitmapImage img = new BitmapImage(new Uri());
img.CacheOption = BitmapCacheOption.None;

Please include a repro project. What exception are you getting?

Either the clipboard contains a file reference, in which case you can create non-caching BitmapImage yourself, or it s a bitmap, in which case it is already in memory, so BitmapCacheOption.None does not make sense.
