New page

First, show how to write basic main function.

<pre>
Tool.c

#include "../inc/Tool.h"
#include "genUtil.h"
#include "mrcImage.h"

int
main(int argc, char* argv[])
{
ToolInfo info; // struct that stores information from argument
lToolInfo linfo; // struct that stores information for API
mrcImage in; // [[mrcImage]] as input
mrcImage out; // [[mrcImage]] as output

// 3 function set that are provided as prototype.
init0(&info); 　　　　　　　　　　　// Initial Setting
argCheck(&info, argc, argv);　　　　// Pass the value from argument.
init1(&info);　　　　　　　　　　　 // Work depending on argument information: e.g. file open or close

mrcFileRead(&in, info.In, "in main", 0); // File read

　　lTool(&out, &in, &linfo, info.mode); // Process "in", and Create "out".
　　　　　　　　　　　　　　　　　　　　　　　 // Generally, function whose first letter is "l" is image process library.

mrcFileWrite(&out, info.Out, "in main", 0); // File write

}
</pre>

Next, show how to write basic image process library. Here, show how to write the program that performs projection along z axis.

<pre>
lTool.c

#include "./lTool.h"
#include "genUtil.h"
#include "mrcImage.h"

void
lTool(mrcImage* out, mrcImage* in, lToolInfo* linfo, int status)
{
mrcImageParaTypeReal x, y, z; // Variable that expresses pixel coordinates
double src, dst; // Store the value of pixel

out->Header = in->Header; // Make same format of output image as input image.
　　out->HeaderN.z = 1; // For Example, deal as 1 pixel data about along z axis.
mrcInit(&out, NULL); // Secure the memory region for output image.

for(z=0; z<in->HeaderN.z; z++)｛
for(y=0; y<in->HeaderN.y; y++)｛
for(x=0; x<in->HeaderN.x; x++)｛
// Get the value of pixel.
mrcPixelDataGet(in, x, y, z, &src, mrcPixelRePart, mrcPixelHowNearest);
mrcPixelDataGet(out, x, y, 0, &dst, mrcPixelRePart, mrcPixelHowNearest);

// Add the value of pixel.
dst += src;

// Set a new value of pixel.
mrcPixelDataSet(out, x, y, 0, dst, mrcPixelRePart);
　 }
}
}
}
</pre>
