[IMAGE-SIG] Numeric Error

[Dale Bertrand]

I've written a c function which returns a string representing 7
doubles.  I wish to convert this string into a Numeric array for further
processing.  Unfortunately, Numeric dumps a core when I call
Numeric.fromstring.  I am sure the string is the right lenghth and have
no idea what is going on.
Shouldn't Numeric accept the data as long as it's the right length?  Is
there something I'm missing?

Thanks in advance.


-- code --
f =
"/vision/medprojects/crisco/shocks/quad1-surfaces/quad1-0.00--0.50-00%d.raw"
% i
print "filename: ", f
shocks_string = sd.detect(f,135,135)
print "length of string: ", len(shocks_string)
print "string: ", shocks_string
aa = Numeric.fromstring(shocks_string, Numeric.Float)
print aa
