Implementations§

Source§

impl ImageMetadata

Source

pub fn new(format: ImageFormat) -> ImageMetadata

Builds metadata from a detected format without embedded size information.

Source

pub fn with_size(format: ImageFormat, size: Option<ImageSize>) -> ImageMetadata

Builds metadata from a detected format and optional size information.

Source§

impl PartialEq for ImageMetadata

Source§

fn eq(&self, other: &ImageMetadata) -> bool
