Hi,
I had more questions on the Danielsson distance map filter. I have set the
input and output of the filter to unsigned char.
I have also put the SetUseImageSpacing flag to true. This means that actual
distances may be computed which are more floating point
numbers.  Since I am forcing the output to unsigned char, then does this
mean that the actual distances are truncated to unsigned char
or are they rounded to it? Is there a better way to handle this?
Thanks
Radhika
