TIOParams.DICOM_JPEGQuality

Declaration

property DICOM_JPEGQuality: integer;

Description

Specifies the quality factor (ranging from 1 to 100) to use when saving a DICOM file as a lossy JPEG (iedcJPEG compression).
Higher values improve image quality but require more disk space.

Default: 80 (Specified by IOParamDefaults)

Note:
◼If you are using a TIEMultiBitmap or TImageEnMView, you can use DuplicateCompressionInfo to propogate the parameter to all frames
◼See JPEG Quality comparisons at: JPEG_Quality

Examples

// Save uncompressed DICOM
ImageEnView1.IO.Params.DICOM_Compression := iedcUncompressed;
ImageEnView1.IO.SaveToFileDICOM( 'C:\image.dicom' );

// Save DICOM with lossy JPEG compression
ImageEnView1.IO.Params.DICOM_Compression := iedcJPEG;
ImageEnView1.IO.Params.DICOM_JPEGQuality := 75;
ImageEnView1.IO.SaveToFileDICOM( 'C:\image.dicom' );

// Save DICOM with lossy JPEG2000 compression
ImageEnView1.IO.Params.DICOM_Compression := iedcJPEG2000;
ImageEnView1.IO.Params.DICOM_J2000Rate := 0.10;
ImageEnView1.IO.SaveToFileDICOM( 'C:\image.dicom' );

// Save DICOM with lossless JPEG2000 compression
ImageEnView1.IO.Params.DICOM_Compression := iedcLosslessJPEG2000;
ImageEnView1.IO.SaveToFileDICOM( 'C:\image.dicom' );
