What we can do with Memory DC in Store App?

    Question

  • Hi,

    In StoreApp supported APIs, I see there are several APIs which create rendering target associated with MemoryDC.

    IDWriteGdiInterop::CreateBitmapRenderTarget() is an example.

    Now, how we can access the bitmap through the MemoryDC?

    I couldn't find find StoreApp supported APIs which can manipulate MemoryDC.

    I want to render a text on a off screen memory bitmap. The bitmap need to be directly accessible from CPU because I need to composite other images on to the bitmap through CPU.

    What is the efficient way to do it?
