icon image sequence thumbnails?

[bsapach]

Hello everyone,

I'm looking for a way to display thumbnail icons of images in my application. I'm assuming I can do this by pulling out DCM_IconImageSequence from a file instance DcmDirectoryRecord. I haven't been able to get it working yet, should I treat it as a DicomImage??? If anyone has an example I'd greatly appreciate it. Here's my code so far:

Code: Select all

file->findAndGetOFStringArray(DCM_ReferencedFileID,val);
path.Format("%s\\%s",DICOMDIRPath,val.data());
FileFormat->loadFile(path.GetBuffer());
DcmDataset * DDataSet = FileFormat->getDataset();
DcmSequenceOfItems * icon;
file->findAndGetSequence(DCM_IconImageSequence,icon);
DicomImage * DImage = new DicomImage(icon,DDataSet->getOriginalXfer(),0,0,0,0,1);

DICOMDIRPath is the path to the folder containing the DICOMDIR file.

thanks!

Beau

The short answer is: Use findAndGetSequenceItem() instead of findAndGetSequence() since the constructor of class DicomImage() expects an DcmItem or a DcmDataset/DcmFileFormat object.
