Struct img_parts::jpeg::JpegSegment

pub struct JpegSegment { /* fields omitted */ }

The representation of a segment making up a Jpeg

Implementations

impl JpegSegment

pub fn new(marker: u8) -> JpegSegment

Construct an empty JpegSegment

pub fn new_with_contents(marker: u8, contents: Bytes) -> JpegSegment

Construct a JpegSegment with contents

pub fn new_with_entropy(
    marker: u8,
    contents: Bytes,
    entropy: Bytes
) -> JpegSegment

Construct a JpegSegment with contents and entropy

pub fn len(&self) -> usize

Get the size of this JpegSegment once it is encoded, entropy excluded.

The size is the sum of:

• The marker (2 bytes).
• The length (2 bytes) if this marker has a length.
• The size of the content.

pub fn len_with_entropy(&self) -> usize

Get the size of this JpegSegment once it is encoded, including the Entropy.

The size is the sum of:

• The marker (2 bytes).
• The length (2 bytes) if this marker has a length.
• The size of the content.
• The size of the encoded entropy data.

pub fn marker(&self) -> u8

Get the second byte of the marker of this JpegSegment

pub fn contents(&self) -> &Bytes

Get the content of this JpegSegment

pub fn has_entropy(&self) -> bool

Check if this JpegSegment has entropy

pub fn encoder(self) -> ImageEncoder<Self>

Create an encoder for this JpegSegment
