Struct WebPProbe 

pub struct WebPProbe {
    pub width: u32,
    pub height: u32,
    pub has_alpha: bool,
    pub has_animation: bool,
    pub frame_count: u32,
    pub bitstream: BitstreamType,
    pub icc_profile: Option<Vec<u8>>,
}

Result of probing a WebP file.

Fields

width: u32

Image dimensions.

height: u32

Image height.

has_alpha: bool

Whether the image has an alpha channel.

has_animation: bool

Whether the image is animated.

frame_count: u32

Number of frames (1 for static images).

bitstream: BitstreamType

Bitstream type with quality details.

icc_profile: Option<Vec<u8>>

ICC color profile, if present.

Implementations

impl WebPProbe

pub fn estimated_quality(&self) -> Option<f32>

Estimated source quality (0-100), or None for lossless.

pub fn recommended_quality(&self) -> Option<f32>

Recommended zenwebp quality for re-encoding that matches the source.

Returns None for lossless files (use lossless re-encoding instead). For lossy files, returns a quality value that should produce similar perceptual quality without unnecessary size bloat.

pub fn is_lossless(&self) -> bool

Whether this file is lossless.

Trait Implementations

impl Clone for WebPProbe

fn clone(&self) -> WebPProbe

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WebPProbe

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

Formats the value using the given formatter.
