WindowsPDFPageMBS.RenderToMemory(Handler as RenderToMemoryFinishedMBS, Options as WindowsPDFPageRenderOptionsMBS = nil)

Calls the handler delegate later with results (or error code).
Produces a MemoryBlock with image data, which you can pass to Picture.FromData to get as picture.

Asynchronous mode will perform the work on a different thread in the background.

WindowsPDFPageMBS.RenderToMemory(Options as WindowsPDFPageRenderOptionsMBS = nil) as MemoryBlock

Takes a set of display settings, applies them to the output of a Portable Document Format (PDF) page's contents, and creates a stream with the customized, rendered output as an synchronous action. This asynchronous action can be used to create a customized display image of the Portable Document Format (PDF) page.

Please call RenderToStream if you need image as string, call RenderToMemory if you need a MemoryBlock and call RenderToPicture if you need a picture.

Var page As WindowsPDFPageMBS // current page
page.RenderToStream AddressOf RenderToStreamFinished

Calls the handler delegate later with results (or error code).
Produces a string with the image data.

Asynchronous mode will perform the work on a different thread in the background.
