Struct JpegParams 

pub struct JpegParams {
    pub quality: u8,
    pub sampling_factor: SamplingFactor,
    pub write_jfif: bool,
}

JPEG baseline/extended encoding parameters.

Fields

quality: u8

JPEG quality factor 1–100. 75 is a typical clinical default.

sampling_factor: SamplingFactor

Chroma sub-sampling factor for color images.

write_jfif: bool

Whether to write a JFIF APP0 header (required for some viewers).

Implementations

impl JpegParams

pub fn lossless() -> Self

High-quality baseline/extended parameters (quality=100, no sub-sampling).

This improves fidelity, but it is still not classic JPEG Lossless Process 14. Use encode_jpeg_lossless(...) for true lossless output.

Trait Implementations

impl Clone for JpegParams

fn clone(&self) -> JpegParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JpegParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for JpegParams

fn default() -> Self

Returns the “default value” for a type.
