Media - FHIR v1.1.0

GAO Ballot Package

This page is part of the FHIR Specification (v1.1.0: STU 3 Ballot 1). The current version which supercedes this version is 5.0.0. For a full list of available versions, see the Directory of published versions . Page versions: R4B R4 R3 R2

This is a frozen snapshot of the FHIR specification created for the purpose of balloting the GAO implementation Guide. It includes draft changes that may be part of the future DSTU 2.1 release but further change is expected. Readers should focus solely on the GAO implementation content, and FHIR DSTU 2 for other purposes.

Media.height
Definition	Height of the image in pixels (photo/video).

Type	positiveInt
Summary	true
Invariants	Affect this element mda-2: Width can only be used for a photo or video (expression: width.empty() or type != 'audio', xpath: not(f:type/@value='audio') or not(f:width))
Media.frames
Definition	The number of frames in a photo. This is used with a multi-page fax, or an imaging acquisition context that takes multiple slices in a single image, or an animated gif. If there is more than one frame, this SHALL have a value in order to alert interface software that a multi-frame capable rendering widget is required.
Control	0..1
Type	positiveInt
Default Value	1
Summary	true
Invariants	Affect this element mda-3: Frames can only be used for a photo (expression: frames.empty() or type = 'photo', xpath: (f:type/@value='photo') or not(f:frames))
