    Keep in mind, that is a LOT of memory you are trying to allocate with that Bitmap.

    Refer to http://social.msdn.microsoft.com/Forums/en-US/netfxbcl/thread/37684999-62c7-4c41-8167-745a2b486583/

    .NET is likely refusing to create an image that uses up that much contiguous memory all at once.

    Slightly harder to read, but this reference helps as well:

    Each image in the system has the amount of memory defined by this formula:

    bit-depth * width * height / 8

    This means that an image 40800 pixels by 4050 will require over 660
    megabytes of memory.
