[Insight-users] crop tool with ITK VTK Qt

[Cary lorey]

I've seen this class but it does not meet my needs, I found a lot of method
eg:
http://www.itk.org/Wiki/ITK/Examples/ImageProcessing/RegionOfInterestImageFilter
http://www.vtk.org/doc/nightly/html/classvtkImageCroppingRegionsWidget.html#details
(no
example)

I think that there is not a method directly to a crop with the mouse on the
image, but I have an idea, Normally, we need a method to retrieve the size
of the cropping rectangle and pass these dimensions to the function of the
crop: cropSize [0] and cropSize [1] by clicking the crop button, the region
of interest is obtained.

I want to know if this is a good method to make a crop with the mouse ?
Thank you
