dicom_core::value::fragments

Struct Fragments

Source
pub struct Fragments { /* private fields */ }
Expand description

Represents the fragments of a single frame.

A PixelFragmentSequence can be generated from a list of Fragments. In case of multi-frame, a list of frames composed by 1 fragment is expected.

The frames can be independently processed, so parallel execution is possible.

§Example

use dicom_core::{DataElement, Tag};
use dicom_core::header::EmptyObject;
use dicom_core::value::Value::PixelSequence;
use dicom_core::value::fragments::Fragments;
use dicom_core::value::InMemFragment;
use dicom_core::VR::OB;

// Frames are represented as Vec<Vec<u8>>
// Single 512x512 frame
let frames = vec![vec![0; 262144]];
let fragments = frames
    .into_iter()
    .map(|frame| Fragments::new(frame, 0))
    .collect::<Vec<Fragments>>();

let element = DataElement::new(
    Tag(0x7FE0, 0x0008),
    OB,
    PixelSequence::<EmptyObject, InMemFragment>(fragments.into())
);

From this last example, it is possible to extend it to implement a pipeline, and even use rayon for parallel processing of the frames.
