Remarks

The value of DocumentCacheOptions.None (the default) means to store only the necessary data needed to re-construct the document and its pages from the cache (for example, when DocumentFactory.LoadFromCache is called.

Other values will try to store the results of getting the page images, SVGs, text, and annotations into the cache to speed up subsequent calls.
