[Insight-users] read rgb values

[alex Dowson]

It’s compiler error of code mistake.


int main( int argc, char * argv[] );
char test;
{

should be
int main( int argc, char * argv[] )
{
    
    char test;

Subject: [Insight-users] read rgb values

I am constructing a program to read rgb values  in a raw image  data set of a human abdomen obtained from a CT scan(VHP abdomen).Slice dimensions are 675,401,450 and spacing0.333 etc.) I used RGBImageSeriesReadeWrite.cxx.I am using itk version 4.2 and CMake2.8.9.  I have constructed and spent many hours on my last error. 



Error:error C2447: '{' : missing function header (old-style formal list?)


Pl help me get it corrected.
Thanks
Shirani
