+3  Q: 

Slice up an image into tiles

Given a loaded Bitmap object. I want to slice up this image into 256x256 tiles and save out each tile as a jpg file.

You may think this as a Silverlight Deep Zoom sort task and you'd be right.

I've got a solution using WPF but I would prefer a solution that would work in the .NET 2.0 framework. GDI+ is not somewhere I've spent any amount of time.

Anyone know how I could go about this? I can't seem to find a "Create Bitmap from a specified rectangle sort of method". I'd be surprised if one doesn't exist but perhaps I can't see the wood for the trees.

+8  A: 

You can use Bitmap.Clone(Rectangle, PixelFormat) to crop out a 256x256 region of a source image. This works in .NET 2.0.

Thanks Reed, that seems pretty straightforward, its obvious that if you want to cut a slice of something you'd call its Clone method. :P

Yeah - Horrible name for that method, but it works quite well.
