creating an image

[Tim Hutton]

Quick question, how do you create a new image now? I want something very
similar to the code on p450 of the book, but updated for vtk2.4
(vtkImageRegion no longer exists). Everything I'm trying makes my code
crash, presumably because things aren't being allocated properly.

Here's an example of what I've been trying:

	vtkImageCache *im = (vtkImageCache*)vtkImageCache::New();

	im->SetWholeExtent(0,100,0,100,0,0);
	im->SetUpdateExtent(0,100,0,100,0,0);

	int x,y;
	for(x=0;x<100;x++)
	{
		for(y=0;y<100;y++)
		{
			*(float*)(im->GetData()->GetScalarPointer(x,y,0)) = 0.0F;
		}
	}

	return im;

Crashes most reliably.

Cheers,

Tim.
