I'm a newbie to V8i and like it a lot!
Especially Descartes, however I was also an avid fan of IrasB and enjoyed the way I could "shrink" the boundary to the extents of the raster pixels with a single tool click. I could change the boundary to my cut line by placing raster pixels in the corners of my border. Shrinking the boundary was also a quick way to determine if all the pixels were erased, since not all pixels display unless you Zoom in.
Resize Canvas in Descartes hasn't any options other than manually changing the boundary. Is there a similar tool within Descartes that changes the boundary by a single mouse click like I had in IRASB?
Descartes does not have a tool that works exactly like the Shrink Border tool in Irasb. The Resize Canvas tool is the tool to use. While shrinking the border may not be as quick you can also increase the size of the border which you could not do in Irasb unless you inserted more data into the layer.
