dcmpstat: a presentation state library and utility apps

This module contains classes that implement a high-level API for the DICOM Softcopy Grayscale Presentation State Storage SOP Class. It also contains various support classes that are used by DICOMscope, a free DICOM viewer that has been developed as a demonstrator for presentation states. See http://dicom.offis.de/dscope

The main interface classes are:

• DVPresentationState
• DVInterface
• DVPSStoredPrint

Tools

This module contains the following command line tools:

• dcmmkcrv: Add 2D curve data to image
• dcmmklut: Create DICOM look-up tables
• dcmp2pgm: Read DICOM image and presentation state and render bitmap
• dcmprscp: DICOM basic grayscale print management SCP
• dcmprscu: Print spooler for presentation state viewer
• dcmpschk: Checking tool for presentation states
• dcmpsmk: Create DICOM grayscale softcopy presentation state
• dcmpsprt: Read DICOM images and presentation states and render print job
• dcmpsrcv: Network receive for presentation state viewer
• dcmpssnd: Network send for presentation state viewer

Examples

The following example shows how to create a default presentation state for a DICOM image:

DcmFileFormat infile;
DcmFileFormat outfile;
if (infile.loadFile("image.dcm").good())
{
  DVPresentationState pstate; // presentation state handler
  if (pstate.createFromImage(*infile.getDataset()).good())
  {
    // serialize presentation state into DICOM data set structure
    if (pstate.write(*outfile.getDataset(), OFFalse).good())
    {
      // and write to file
      outfile.saveFile("gsps.dcm", EXS_LittleEndianExplicit);
    }
  }
}

The following example shows how to apply the grayscale transformation pipeline from a presentation state to a DICOM image:

DcmFileFormat imagefile;
DcmFileFormat gspsfile;
if (imagefile.loadFile("image.dcm").good() &&
    gspsfile.loadFile("gsps.dcm").good())
{
  DVPresentationState pstate; // presentation state handler
  if (pstate.read(*gspsfile.getDataset()).good()) // parse gsps object
  {
    // attach presentation state to image data
    if (pstate.attachImage(&imagefile, OFFalse).good())
    {
      const void *pixel; // pointer to pixel data, one byte per pixel
      unsigned long width;   // width of image bitmap
      unsigned long height;  // height of image bitmap
      if (pstate.getPixelData(pixel, width, height).good())
      {
        /* do something useful with the pixel data */
      }
      pstate.detachImage(); // release connection between GSPS and image
    }
  }
}
