Hi,

I am trying to create a dll using ITK. I am trying a very simple application:

---------------
    typedef itk::Image< unsigned short, 3 > ImageType;
   
    ImageType::Pointer image = ImageType::New();
    std::cout << "ITK Hello World !" << std::endl;
    FILE *f;
    f = fopen("c:/temp/itk.txt","w");
    fprintf(f,"itk : hello world!!!\n");
    fclose(f);
------------------

There is nothing more in it. But I have some problems with msvc 6.0. I modified the makefile (.mak) exported from Visual C++ project, included all the ITK libraries, and other necessary libraries. But when I try to compile (make) it with nmake provided by msvc 6.0:

How this can happen?? How can it be unable to find cout??? I don't know what to do.

I know that this is a really bad idea to use visual c++ 6.0 compiler, as it is old and does not complies with ANSI C++. But I have to use it. I managed to compile it as a static library, but I need a dynamic one.

Anybody has an idea?

Thanks in advance,

Hi Luis,

my CMakeLists.txt file is:

-----------------------------------------------------
PROJECT(myitk)

# Find ITK.
FIND_PACKAGE(ITK)
IF(ITK_FOUND)
  INCLUDE(${ITK_USE_FILE})
ELSE(ITK_FOUND)
  MESSAGE(FATAL_ERROR
          "Cannot build without ITK.  Please set ITK_DIR.")
ENDIF(ITK_FOUND)

ADD_LIBRARY(mytik SHARED myitk.cxx)
---------------------------------------------------------------------------

Thanks a lot,

haris

Hi,

I'm trying to rigidly transform some 3D image data for test in registration, but can't seem to figure out what kind problems I'm running into:

1)  The program only seems to resample the 1st out of a total of 12 slices from my 3D image, all other slices are just a repeat of the first slice.  I tried playing around with spacing[2] = x for Dimension = 3 where x is any value greater than 0, but instead the program would give me every slice other than the 1st one black.

2)  Also, all the output images seem to give me really high brightness and contrast values.  For example my original images have brightness = 2204933.4355 and contrast = 4277002.0027, and the output would be brightness = 44324303030.1732 and contrast = 9999999.0000.  Does this have to do with the fact that I changeed the InputPixelType and OutputPixelType to float?

In generally I think it's my spacing and maybe origin values that are creating these problems, so here are what I think they should be:

Spacing (or in ANALYZE, Size) (mm):  x = 0.01, y = 0.01, z = 0.00
Origin (same name in ANALYZE) (vxl):  x = 0.00, y = 0.00, z = 0.00


Thank You,
Kevin
