Remarks

JPEG 2000 is a wavelet-based compression stored in a hierarchical format, which contains several stored resolutions of the image in the same bit-stream without duplication. For that reason, a JPEG 2000 compressed image can then be sent to a device in the resolution that best fits, without additional storage overhead.

The LEADTOOLS JPEG 2000 Plug in provides support for encoding and decoding a JPEG 2000 bit-stream. The JPEG 2000 compression provides greater flexibility and better image quality, especially at higher compression ratios, than standard JPEG. The greater flexibility includes the ability to control:

• • whether or not to transform RGB images to YUV prior to compression
  • the type of quantization to use when determining the quantization step size
  • the amount of compression
  • the size and location of tiles
  • the number of resolution levels in the bit-stream
  • the progression order
  • the code block height and width
  • whether to use markers to help detect corruption during transmission
  • etc.

LEADTOOLS provides the DicomDataSet.Jpeg2000Options property for controlling the JPEG 2000 features listed above.

To get the default settings for the JPEG2000 features, use the DicomDataSet.DefaultJpeg2000Options property.
