Parameters

args

Standard argument for PrepareCompress

• For some compression methods, a transform is needed to bring the data into the 12 bit unsigned range (e.g. JPEG lossy extended)
• For colour images, the photometric interpretation of the dataset may need to be changed to (e.g. to YBR_FULL_422 for JPEG lossy)

By changing the values in ModificationArguments, a compressor can control how the pixel data is passed to it by DicomObjects, or how some other values are later changed:

Setting ModificationArgs.LossyDescription to a human description and and ModificationArgs.LossyMethod to a codec values (e.g. "ISO_10918_1" for JPEG)
