Hi,
When morph_distance is employed on images that have distances >256, IDL
crashes. Has anyone else had this problem? If so, is there a work-around
I can not rebin my image to a smaller image). Does anyone have a version
that returns an int image instead? Also, can anyone tell me where the
error logs are kept?
Thanks, Delia

Hi,
I have not seen this problem. In my experience, MORPH_DISTANCE does not
crash when creating distance maps with distances of greater than 256, which
is what I think you are asking. On my machine, MORPH_DISTANCE outputs arrays
of type INT or UINT unless NEIGHBOR_SAMPLING is set to 3. Could you
clarify the problem or post the code that crashes?
There is an !ERROR _STATE system variable which logs the most recent error.

Hi,
I found a similar problem. If you try
help,morph_distance(bytarr(128),neigh=3) idl crashes.
With singular points try first a dilation to get reliable distances
(reliable means greater than 1).
