Expand description

A DICOM object trait to be interpreted as pixel data.

This trait extends the concept of DICOM object as defined in dicom_object, in order to retrieve important pieces of the object for pixel data decoding into images or multi-dimensional arrays.

It is defined in this crate so that transfer syntax implementers only have to depend on dicom_encoding.

Required Methods§

Source

fn transfer_syntax_uid(&self) -> &str

Return the object’s transfer syntax UID.

Source

fn rows(&self) -> Option<u16>

Return the Rows, or None if it is not found

Source

fn cols(&self) -> Option<u16>

Return the Columns, or None if it is not found

Source

fn samples_per_pixel(&self) -> Option<u16>

Return the Samples Per Pixel, or None if it is not found

Source

fn bits_allocated(&self) -> Option<u16>

Return the Bits Allocated, or None if it is not defined

Source

fn bits_stored(&self) -> Option<u16>

Return the Bits Stored, or None if it is not defined

Source

fn photometric_interpretation(&self) -> Option<&str>

Return the Photometric Interpretation, with trailing whitespace removed, or None if it is not defined

Source

fn number_of_frames(&self) -> Option<u32>

Return the Number Of Frames, or None if it is not defined

Source

fn number_of_fragments(&self) -> Option<u32>

Returns the Number of Fragments, or None for native pixel data

Source

fn fragment(&self, fragment: usize) -> Option<Cow<'_, [u8]>>

Return a specific encoded pixel fragment by index (where 0 is the first fragment after the basic offset table) as a Cow<[u8]>, or None if no such fragment is available.

In the case of native (non-encapsulated) pixel data, the whole data may be obtained by requesting fragment number 0.
