#define problem

Andreas

Hi!

I'm using an IplImage library from camellia.sourceforge.net, and the
testbench calls a file only containing code like the one below. In
cam_morphomaths_code.c the real computation is made, but I don't
understand where cam_morphomaths_code.c is included and how to set
what parameters to use in the testbench.

How does this code execure? I don't understand a bit...

#undef CAM_MM_NEIGHB
#define CAM_MM_NEIGHB 5
#include "cam_morphomaths_code.c"

#define CAM_MM_ONE_OP

#undef CAM_MM_NEIGHB
#define CAM_MM_NEIGHB 3
#define CAM_MM_DO_EROSION
#define CamMorphoMathsKernel CamErode3x3
#define CamMorphoMathsKernel1U CamErode3x31U
#include "cam_morphomaths_code.c"
#undef CamMorphoMathsKernel
#undef CamMorphoMathsKernel1U
#undef CAM_MM_DO_EROSION
#define CAM_MM_DO_DILATION
#define CamMorphoMathsKernel CamDilate3x3

#include "cam_morphomaths_code.c"
#undef CAM_MM_DO_DILATION
#undef CamMorphoMathsKernel
#undef CamMorphoMathsKernel1U

#undef CAM_MM_NEIGHB
#define CAM_MM_NEIGHB 5
#define CAM_MM_DO_EROSION
#define CamMorphoMathsKernel CamErode5x5
#define CamMorphoMathsKernel1U CamErode5x51U
#include "cam_morphomaths_code.c"
#undef CamMorphoMathsKernel
#undef CamMorphoMathsKernel1U
#undef CAM_MM_DO_EROSION
#define CAM_MM_DO_DILATION
#define CamMorphoMathsKernel CamDilate5x5
#define CamMorphoMathsKernel1U CamDilate5x51U
#include "cam_morphomaths_code.c"
#undef CAM_MM_DO_DILATION
#undef CamMorphoMathsKernel
#undef CamMorphoMathsKernel1U

Each time you include the .c source file, this "harness" re-defines
certain manifest constants that proabably change the behavior of the C
module. Each include actually ends up producing a new instantiation of the
source code, modified by the manifest constants. The functions in the .c
file are changed for each inclusion to prevent name-space clashes. What's
not to understand?

Thanks!

Now it's kind of obvious.
