Detailed Description

enumerations, error constants and helper functions for the dcmjpls module

Enumeration Type Documentation

JLS_CompressionBitDepth

enum JLS_CompressionBitDepth

describes how the encoder handles the image bit depth upon lossy compression.

Enumerator
EJLSBD_original	keep original bit depth
EJLSBD_limit	limit bit depth to a certain value, i.e. scale down if the original image bit depth is larger
EJLSBD_force	force bit depth to a certain value, i.e. scale up or scale down the original image to match the given bit depth.

JLS_PlanarConfiguration

enum JLS_PlanarConfiguration

describes how the decoder should handle planar configuration of decompressed color images.

Enumerator
EJLSPC_restore	restore planar configuration as indicated in data set
EJLSPC_auto	automatically determine whether color-by-plane is required from the SOP Class UID and decompressed photometric interpretation
EJLSPC_colorByPixel	always create color-by-pixel planar configuration
EJLSPC_colorByPlane	always create color-by-plane planar configuration

JLS_UIDCreation

enum JLS_UIDCreation

describes the condition under which a compressed or decompressed image receives a new SOP instance UID.

Enumerator
EJLSUC_default	Upon compression, assign new SOP instance UID if compression is lossy. Upon decompression never assign new SOP instance UID.
EJLSUC_always	always assign new SOP instance UID on compression and decompression
EJLSUC_never	never assign new SOP instance UID
