I'm currently using DotImage 4.0 and haven't had any luck getting the normal AutoCrop command to work:

AutoCropCommand cropCmd = new AutoCropCommand();
img = cropCmd.Apply(img).Image;

My image is just a black and white document, but running the command doesn't do anything. I've tried returning the frame size using the AutoCropCommand and it's the same as the original image. Is there something I'm missing?

Cheers

Andy
