Problems with DicomImage

[juan_7_89]

Hi! I'm having problems using DicomImage. I have wrote this code and it works well

#include <stdio.h>
#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dctk.h"

#include "dcmtk/dcmimage/diregist.h" /* include to support color images */
#include "dcmtk/dcmimgle/dcmimage.h" /* for DicomImage */




using namespace std;
//using namespace cimg_library;

int main(int argc, char *argv[]) {
//Clase que maneja los archivos (cabeceras + datos)
DcmFileFormat FileFormat;
//abrimos el archivo y guardamos el estado de la apertura
OFCondition status = FileFormat.loadFile("test3.dcm");

if (status.good())
{
const Uint16 * pixelData = NULL;
Uint16 lRows = 0;
Uint16 lCols = 0;

//clase que maneja los datos (valores de los pixeles)
DcmDataset *lDataset = FileFormat.getDataset();

//leemos atributos (pixeldata, lrows, lcols);
lDataset->findAndGetUint16Array(DCM_PixelData, pixelData);
lDataset->findAndGetUint16(DCM_Rows, lRows);
lDataset->findAndGetUint16(DCM_Columns, lCols);

cout<< lCols*lRows;

} else
cerr << "Error: cannot read DICOM file (" << status.text() << ")" << endl;

return 0;
}

but when I change the code and add a line with "DicomImage ("test.dcm")" i've got some errors.

This is the final code:

#include <stdio.h>
#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dctk.h"

#include "dcmtk/dcmimage/diregist.h" /* include to support color images */
#include "dcmtk/dcmimgle/dcmimage.h" /* for DicomImage */




using namespace std;
//using namespace cimg_library;

int main(int argc, char *argv[]) {
//Clase que maneja los archivos (cabeceras + datos)
DcmFileFormat FileFormat;
DicomImage ("test.dcm");
//abrimos el archivo y guardamos el estado de la apertura
OFCondition status = FileFormat.loadFile("test3.dcm");

if (status.good())
{
const Uint16 * pixelData = NULL;
Uint16 lRows = 0;
Uint16 lCols = 0;

//clase que maneja los datos (valores de los pixeles)
DcmDataset *lDataset = FileFormat.getDataset();

//leemos atributos (pixeldata, lrows, lcols);
lDataset->findAndGetUint16Array(DCM_PixelData, pixelData);
lDataset->findAndGetUint16(DCM_Rows, lRows);
lDataset->findAndGetUint16(DCM_Columns, lCols);

cout<< lCols*lRows;

} else
cerr << "Error: cannot read DICOM file (" << status.text() << ")" << endl;



return 0;
}

this is the message:

/usr/local/include/dcmtk/dcmimage/diregist.h:90: error: undefined reference to 'DiRegister::DiRegister()'
/usr/local/include/dcmtk/dcmimage/diregist.h:90: error: undefined reference to 'DiRegister::~DiRegister()'

and this is my MakeFile

GPP=g++
GCC=gcc
FLAGS= -fshow-column -g2 -Wall -O0 -Wall -pedantic-errors -DHAVE_CONFIG_H -O0 -D_DEBUG
LIBS= -L/usr/local/lib -L/usr/local/include -ldcmimgle -ldcmdata -loflog -lofstd -lz -lpthread -lm -lX11
OBJS=Debug/main.o

all: Debug Debug/ImgDicom.bin

clean:
rm -rf ${OBJS} Debug/ImgDicom.bin

Debug/ImgDicom.bin: ${OBJS}
${GPP} ${OBJS} ${LIBS} -o $@

Debug:
mkdir Debug

Debug/main.o: main.cpp CImg.h
${GPP} ${FLAGS} -c main.cpp -o $@

Can anyone help me?
Thanks!

EDIT: It works if i supress the header #include "dcmtk/dcmimage/diregist.h"

Of course, if you include a header file from the "dcmimage" module, you also have to link the corresponding library (dcmimage). So, if you need support for color images, add "dcmimage" (and include "diregist.h").

Thanks! I'm now having problems with this

#include <stdio.h>
#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dctk.h"

#include "dcmtk/dcmimage/diregist.h"
//libreria para manejar el dataset
#include "dcmtk/dcmimgle/dcmimage.h" /* for DicomImage */

//libreria para manejar las decodificaciones
#include "dcmtk/dcmjpls/djdecode.h"




using namespace std;
//using namespace cimg_library;

int main(int argc, char *argv[]) {
//funcion que determina varios parametros de decodificacion
DJLSDecoderRegistration::registerCodecs();
//Clase que maneja los archivos (cabeceras + datos)
DcmFileFormat FileFormat;
//Clase que sólo la imagen dicom!
DicomImage ("test.dcm");

and this is the error message

usr/local/lib/libdcmjpls.a(djcodecd.o):djcodecd.cc:function DJLSDecoderBase::decodeFrame(DcmPixelSequence*, DJLSCodecParameter const*, DcmItem*, unsigned int, unsigned int&, void*, unsigned int, int, unsigned short, unsigned short, unsigned short, unsigned short): error: undefined reference to 'JpegLsReadHeader'
/usr/local/lib/libdcmjpls.a(djcodecd.o):djcodecd.cc:function DJLSDecoderBase::decodeFrame(DcmPixelSequence*, DJLSCodecParameter const*, DcmItem*, unsigned int, unsigned int&, void*, unsigned int, int, unsigned short, unsigned short, unsigned short, unsigned short): error: undefined reference to 'JpegLsDecode'

i'm including this libs:

ijg8 ijg12 ijg16 dcmimgle dcmimage dcmjpls dcmdata oflog ofstd z pthread m X11

Am i missing a header?

[J. Riesmeier]

You have registered the JPEG-LS decoders but link the JPEG libraries. These are two totally different compression schemes!

[juan_7_89]

you are right! Thanks again!

and what libs do i need? because my error message is this now:

/home/juampi/projects/ImgDicom/main.cpp:20: error: undefined reference to 'DJDecoderRegistration::registerCodecs(E_DecompressionColorSpaceConversion, E_UIDCreation, E_PlanarConfiguration, bool)'
/home/juampi/projects/ImgDicom/main.cpp:48: error: undefined reference to 'DJDecoderRegistration::cleanup()'

[J. Riesmeier]

I guess that "dcmjpeg" is missing. Also see FAQ #27.

[juan_7_89]

Thank you very much!
That was the problem
