FAQ #20: Error "cannot change to unencapsulated representation for pixel data"

#1 Post by Jörg Riesmeier » Fri, 2004-11-05, 11:56

:?: Using the "DicomImage" class to handle DICOM images I get the following error message when accesing the pixel data:
ERROR: cannot change to unencapsulated representation for pixel data

:!: It seems that the image is compressed. If it uses a JPEG compression scheme you need to register the JPEG decompressor code:
  • add '#include "djdecode.h"' to your source file
  • call 'DJDecoderRegistration::registerCodecs();' at program init
  • call 'DJDecoderRegistration::cleanup();' before program exit
That should be all you need to do. See Doxygen documentation for details.
