I'm getting the "parameter is not valid" error when doing something simple like this:

Bitmap

temp = new Bitmap(16000, 16000);

I thought the limitation is 32767? It seems I can go up to around 14000 before this error starts cropping up

Use a 64 bit OS. You need contiguous memory. Typically about 500 MB on a 32 bit OS.

Hi Derek,

Thank you for the feedback. I can reproduce it on my computer.

When I tested the code on my computer, at first, it didn’t popup that error message. But my physical memory usage reached a very high rate. When the code was run the second time, the error message “Parameter is not valid�popup. If I run the code under VS debug mode, my computer almost dead.

So I think it is not the limitation of the .NET but the limitation of computer memory. I have installed 2 GB memory on my computer which allows me to run the code once. Could you please tell me why you want to create such large bitmap? Do you have any other way to implement it?

Sincerely,
Kira Qian
