IMAGE message for 2D/3D medical image data

OpenIGTLink Specification

• Message type: “IMAGE”
• Header: VERSION (uint16) + NUM_COMPONENTS (uint8) + SCALAR_TYPE (uint8) + ENDIAN (uint8) + COORD (uint8) + SIZE (uint16[3]) + MATRIX (float32[12])
• Header size: 2 + 1 + 1 + 1 + 1 + 6 + 48 = 60 bytes
• Followed by image data

Fields

version: u16

Protocol version (should be 1 or 2)

num_components: u8

Number of components (1=scalar, 3=RGB, 4=RGBA)

scalar_type: ImageScalarType

Scalar type

endian: Endian

Endianness of image data

coordinate: CoordinateSystem

Coordinate system

size: [u16; 3]

Image size [columns, rows, slices]

matrix: [[f32; 4]; 3]

4x3 transformation matrix (stored row-major, upper 3x4 of 4x4 matrix)

data: Vec<u8>

Image data (raw bytes)

Implementations

impl ImageMessage

pub fn new( scalar_type: ImageScalarType, size: [u16; 3], data: Vec<u8>, ) -> Result<Self>

Create a new IMAGE message

pub fn rgb( scalar_type: ImageScalarType, size: [u16; 3], data: Vec<u8>, ) -> Result<Self>

Create with RGB components

pub fn with_matrix(self, matrix: [[f32; 4]; 3]) -> Self

Set transformation matrix

pub fn with_coordinate(self, coordinate: CoordinateSystem) -> Self

Set coordinate system

pub fn num_pixels(&self) -> usize

Get total number of pixels

Trait Implementations

impl Clone for ImageMessage

fn clone(&self) -> ImageMessage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageMessage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Message for ImageMessage

fn message_type() -> &'static str

Returns the message type name (e.g., “TRANSFORM”, “IMAGE”)

fn encode_content(&self) -> Result<Vec<u8>>

Encode message content to bytes

fn decode_content(data: &[u8]) -> Result<Self>

Decode message content from bytes

impl PartialEq for ImageMessage

fn eq(&self, other: &ImageMessage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
