Parameters

Stream

The Stream from which to read.

TransferSyntax

Specifies the full UID of the transfer syntax with which the file is to be saved when Part 10 format is used. If omitted, the little-endian explicit VR transfer syntax is used. For details of the currently supported syntaxes, see the entry.

Quality

The quality factor to be used. This is a generic compression quality depending on the Transfer Syntax used. This value for JPEG Baseline and JPEG Extended compression represents an integer between 0 – 100. This tells DicomObjects to set up the compressor to try to achieve the quality in percentage (higher quality value towards 100 means better quality and lower compression ratio). And for JPEG-LS Lossy and JPEG2000 Lossy compression this value is actually the desired compression ratio, i.e. if you set the quality value to 10, it tells DicomObjects to try to achieve compression ratio of 10. The actual compression ratio achieved will not be exactly the same as specified by quality value but close enough. The actual compression ratio is calculated based on the original data size and the compressed data size before it is added to “Lossy Image Compression Ratio” tag of the image. For Video compression, this value directly corresponds to the BitsPerSecond of the compressed video.

The stream object may subsequently be read by one of the Read method overloads or by other DICOM software.

Quality is specific to the compression method being used, and is ignored for non-compressed or lossless JPEG transfer syntaxes. For Lossy JPEG, it is an integer in the range 1-100, the higher the number, the better the quality (and the larger the file) , and for JPEG 2000 lossy, it is a compression ratio. Other compression methods may use this for other purposes in the future.

This method is particularly suitable for use with Delphi, which provides access to streams via classes such as TStreamAdapter.
