H.4.2.2.1 N-CREATE

The N-CREATE is used to create an instance of the Basic Film Box SOP Class.

H.4.2.2.1.1 Attributes

The Attribute list of the N-CREATE is shown in Table H.4-6.

Requested Resolution ID (2020,0050) U/U
ICC Profile (0028,2000) U/U

The meaning of the Usage SCU/SCP is described in Section H.2.4.

If the Illumination (2010,015E) and Reflected Ambient Light (2010,0160) values, respectively termed L0 and La, are not created, the following default values are recommended for grayscale printing:

For transmissive film: L0 = 2000 cd/m2. La = 10 cd/m2.

For reflective media: L0 = 150 cd/m2.

The ICC Profile (0028,2000) attribute shall only be used to describe the color space of images for color printing, i.e., in conjunction with the Basic Color Image Box SOP Class. It shall not be used with the Basic Grayscale Image Box SOP Class.

H.4.2.2.1.2 Status

The status values which are specific for this SOP Class are defined as follows:

Status Meaning Code
Success Film Box successfully created 0000
Warning Requested Min Density or Max Density outside of printer’s operating range. The printer will use its respective minimum or maximum density value instead. B605
Failure There is an existing Film Box that has not been printed and N-ACTION at the Film Session level is not supported. A new Film Box will not be created when a previous Film Box has not been printed. C616

H.4.2.2.1.3 Behavior

The SCU uses the N-CREATE to request the SCP to create a Basic Film Box SOP Instance. The SCU shall initialize Attributes of the SOP Class as specified in Section H.2.4.

The SCP shall create the SOP Instance and shall initialize Attributes of the SOP Class as specified in Section H.2.4.

Note: If there exists a Film Box SOP Instance that has not been printed and the SCP does not support N-ACTION on the Film Session, then the SCP should fail the N-CREATE of the new SOP Instance.

Upon the creation of the Basic Film Box SOP Instance, the SCP shall append the SOP Class/Instance UID pair of the created Basic Film Box SOP Instance to the Attribute Referenced Film Box Sequence (2000,0500) of the parent Basic Film Session SOP Instance to link the Basic Film Box SOP Instance to the Basic Film Session SOP Instance.

The SCP shall create Image Box SOP Instances of the appropriate Image Box SOP Class for each image box as defined by the Attribute Image Display Format (2010,0010). The SOP Class of the created Image Box SOP Instance depends on the Meta SOP Class context. For example the Grayscale Image Box SOP Class is related to the Basic Grayscale Print Management Meta SOP Class. The Meta SOP Class context is conveyed by the Presentation Context ID that corresponds with the Meta SOP Class and is defined at Association setup.

The SCP shall append the SOP Class/Instance UID pair of the created Image Box SOP Instance to the Referenced Image Box Sequence Attribute of the parent Basic Film Box SOP Instance to link each Image Box SOP Instance to the Basic Film Box SOP Instance. The SCP returns the list of Image Box SOP Class/Instance UID pairs in the Attribute Referenced Image Box Sequence (2010,0510) of the N-CREATE response message.

If supported, the SCP shall create Basic Annotation Box SOP Instances for each Annotation Box defined by the Attribute Annotation Display Format ID and shall append the SOP Class/Instance UID pair of the created Basic Annotation Box SOP Instance to the Referenced Annotation Box Sequence Attribute of the parent Basic Film Box SOP Instance to link each Basic Annotation Box SOP Instance to the Basic Film Box SOP Instance. The SCP returns the list of Basic Annotation Box SOP Class/Instance UID pairs in the Attribute Referenced Annotation Box Sequence of the N-CREATE response message. The Annotation Boxes shall support the same character sets as the Basic Film Box.

The character set supported by the Film Box shall be the same as the character set of the Basic Film Session.

The SCP shall return the status code of the requested SOP Instance creation. The meaning of success, warning, and failure status codes is defined in Section H.2.5.
