Implementations

impl ImageFormat

pub fn from_extension<S>(ext: S) -> Option<ImageFormat> where
    S: AsRef<OsStr>, 

Return the image format specified by a path’s file extension.

Example

use image::ImageFormat;

let format = ImageFormat::from_extension("jpg");
assert_eq!(format, Some(ImageFormat::Jpeg));

pub fn from_path<P>(path: P) -> Result<ImageFormat, ImageError> where
    P: AsRef<Path>, 

Return the image format specified by the path’s file extension.

Example

use image::ImageFormat;

let format = ImageFormat::from_path("images/ferris.png")?;
assert_eq!(format, ImageFormat::Png);

pub fn can_read(&self) -> bool

Return if the ImageFormat can be decoded by the lib.

pub fn can_write(&self) -> bool

Return if the ImageFormat can be encoded by the lib.

pub fn extensions_str(self) -> &'static [&'static str]

Return a list of applicable extensions for this format.

All currently recognized image formats specify at least on extension but for future compatibility you should not rely on this fact. The list may be empty if the format has no recognized file representation, for example in case it is used as a purely transient memory format.

The method name extensions remains reserved for introducing another method in the future that yields a slice of OsStr which is blocked by several features of const evaluation.

Trait Implementations

impl Clone for ImageFormat

pub fn clone(&self) -> ImageFormat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImageFormat

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

Formats the value using the given formatter.

impl Hash for ImageFormat

pub fn hash<__H>(&self, state: &mut __H) where
    __H: Hasher, 

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.
