Struct img_parts::jpeg::Jpeg

pub struct Jpeg { /* private fields */ }

The representation of a Jpeg image.

Implementations

impl Jpeg

pub fn from_bytes(b: Bytes) -> Result<Jpeg>

Create a Jpeg from Bytes

Errors

This method fails if the file signature doesn’t match or if it is corrupted or truncated.

pub fn segments(&self) -> &Vec<JpegSegment>

Get the segments of this Jpeg

pub fn segments_mut(&mut self) -> &mut Vec<JpegSegment>

Get a mutable reference to the segments of this Jpeg

pub fn segment_by_marker(&self, marker: u8) -> Option<&JpegSegment>

Get the first segment with a marker of marker

pub fn segments_by_marker(
    &self,
    marker: u8
) -> impl Iterator<Item = &JpegSegment>

Get every segment with a marker of marker

pub fn remove_segments_by_marker(&mut self, marker: u8)

Remove every segment with a marker of marker

pub fn len(&self) -> usize

Get the total size of the Jpeg once it is encoded

The size is the sum of:

• The SOI marker (2 bytes).
• The size of every segment including the size of the encoded entropy.

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

Create an encoder for this Jpeg
