Struct immeta::formats::jpeg::Metadata

pub struct Metadata {
    pub dimensions: Dimensions,
    pub sample_precision: u8,
    pub coding_process: CodingProcess,
    pub entropy_coding: EntropyCoding,
    pub baseline: bool,
    pub differential: bool,
}

Represents metadata of a JPEG image.

It provides information contained in JPEG frame header, including image dimensions, coding process type and entropy coding type.

Fields

dimensions: Dimensions

Image size.

sample_precision: u8

Sample precision (in bits).

coding_process: CodingProcess

Image coding process type.

entropy_coding: EntropyCoding

Image entropy coding type.

baseline: bool

Whether this image uses a baseline DCT encoding.

differential: bool

Whether this image uses a differential encoding.

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for Metadata

fn eq(&self, __arg_0: &Metadata) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Metadata) -> bool

This method tests for !=.

impl Eq for Metadata

impl Debug for Metadata

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl LoadableMetadata for Metadata

fn load<R: ?Sized + BufRead>(r: &mut R) -> Result<Metadata>

Loads the implementing type from the given buffered input stream.

fn load_from_seek<R: ?Sized + BufRead + Seek>(r: &mut R) -> Result<Self>

Loads the implementing type from the given buffered and seekable input stream.

fn load_from_file<P: AsRef<Path>>(path: P) -> Result<Self>
