Create Huge Bitmap

Question

I need to create a very large bitmap with dimensions 13056 width, 14336 height. However when I do this code:

Bitmap WorldMap = new Bitmap(13056, 14336);

I receive this error: "ArgumentException was not handled: Parameter is not valid"

The reason I need to create such a large image is that I am 'stitching' alot of other images together.

Thankyou

You are getting Error Because of if you create 13056x14336 bitmap mean you are allocating 13056*14336*4 bytes approximately 600-700 MB Check if you Have 600-700 MB Free Ram and having Visual Studio Also Be run at Same time I Have 2 GB RAM i can run the code till 18000*18000 after that its cause the exception . that's the reason you are Getting this Exception . .NET GDI+ is not the best engine for image editing. and Try 64Bit OS for using Some More memory :) Conclusion : - Get More RAM the more larger Bitmap You can Create :) if answer helped you Mark " Do you like Answer " please :)

I am also seeing this problem when creating a large bitmap (16384 x 16384). I am combining a bunch of othere textures into a single power of two texture. For the meantime, I am simply reducing the image sizes before combining them but I would much rather find a solution to this so it could work with any image... I think this might be related to a run-time memory or stack overflow...I would love to hear someone chime in on this one...

I am having the same problem with the same error occuring. I am stitching together many other bitmaps into one large bitmap. I would like to handle sizes up to at least a gig if possible. The problem is when I create a bitmap with a width/height greater than around 10000 pixels it crashes. Any idea how to get around this? Edit: I forgot to mention that I am running on a machine with 4 GB of RAM. I'm assuming this is a memory limitation of the system, but I would think that it wouldn't crash on images that would only be 500 MBs or so. Can I change something in my system to help?

James, Are you 100 percent positive this is the line of code that is throwing the exception? I don't think that this is the line of code throwing the exception since I am able to run that line of code without receiving the exception. I suggest taking a look at your stack trace. Carl
