I want to create large image by C#. (i have some photos with large size (4800 * 4800). i want to merge these photos.)
I use Bitmap but don't support. (Error : Invalid Parameter)

Some code would be useful ...
... However, to hazard an educated guess, I suspect you're trying to create an instance of Bitmap with either Width or Height (or both) greater than 2^15.
Essentially, you can't - the .NET bitmap classes have a limitation on how big an image they can handle. Your original 4800 pixel square images won't be a problem, but going over 32,767 pixels will be.

But it *will* be a problem even with "smaller" bitmaps. A 4800^2 bitmap requires 88Mb of *contigous* memory. Juggling around several of those simultaneously may cause an out of memory exception.

That's true - I've written a couple of image processing toys that ran out of memory because of naive assumptions on my part. They didn't fail with an "Invalid Parameter" error though, so I didn't think it relevant to the original question. You make a good point though - trying to load and process too many 4800x4800 images will blow out memory consumption, especially if very many copies are kept around.

Hi, you might like to check AForge.NET, it has a large image processor built in, and it's open source.
