[Insight-developers] Problem again in NRRDIO

[Gordon L. Kindlmann]

Hello,

Ok, so the question is, *how* is nrrdStateGrayscaleImage3D listed?   
there is probably some cryptic single letter code that identifies the  
type of symbol.  mangle.pl is using these letter codes to distinguish  
between symbols that the NrrdIO library is actually supplying, versus  
merely using, and the problem is that nrrdStateGrayscaleImage3D is  
actually being supplied, but is not being recorded as such in the  
output of mangle.pl.  Line 66 of mangle.pl is where this decision is  
made; so it may need tweaking.
