Thanks for the help ...
one last question ..
is there any way to find out witch compression is being used on the image ?

Jörg Riesmeier wrote:That means the image is compressed. If the transfer syntax indicates that a JPEG compression has been used, you could try to convert the pixel data using "dcmj2pnm" (with a "j" in the name).

well can you tell me which API to use for this and how ...??

What is the output of the command line tool dcm2pnm in verbose/debug mode? dcm2pnm -v test.dcm reading DICOM file: test.dcm preparing pixel data. ERROR: cannot change to unencapsulated representation for pixel data ! $dcmtk: dcm2pnm v3.5.4 2005-12-20 $ dcm2pnm: Convert DICOM images to PGM/PPM, PNG ...

I have written this code int main() { DicomImage *image = new DicomImage("test_old.dcm"); if (image != NULL) { cout << "Image Status : " << image->getStatus() << endl; ········ if (image->getStatus() == EIS_Normal) { cout << "Imahe Status is Normal"; char *pixelData = (...

I have monochrome image ... and i found that if i dont check dicomImage->isMonochrome() and calles SetWindow then it wont work ...
but now its working after checking ...

Hi i Have written a code which get data from DicomImage and i am trying to setWidow (center, width ) but no change in output image #include <dcmtk/dcmimgle/dcmimage.h> #include <QImage> int main() { DicomImage *image = new DicomImage("test.dcm"); if (image != NULL) { cout << "Image St...

Hi I have written the code to convert one dicom image to jpeg as follow reference DCMTK doc. the output image won't open its the corrupted image any idea whats wrong ? #define HAVE_CONFIG_H #include <dcmtk/dcmjpeg/djencode.h> #include <dcmtk/dcmjpeg/djrplol.h> #include <dcmtk/dcmdata/dcfilefo.h> #in...

Hi Thanks a lot it works :) Hi, Uint32 numPixels = image->getWidth() * image->getHeight(); for (Uint32 i=0; i < numPixels; i++) { out << "the data at position i"<< "=" << i << " is " << *pixelData[i] << OFendl; } I did not compile it but you see how it should work in ge...

on first sight: you are just printing the first value in pixel data-- if this is 0 (i.e. probably black), well then your program outputs 0

Best regards,

hi could you please tell me how to take the next values here really have no idea how to go about it

I am totally new to the DICOM imaging and DCMTK i wrote this code, looking at documentation . but in pixelData i am getting \000 any idea is that correct and #define HAVE_CONFIG_H #include <dcmtk/dcmimage/diregist.h> /* required to support color images */ #include <dcmtk/dcmjpeg/djencode.h> #include...
