Implementations§
source§impl ImageFormat
impl ImageFormat
sourcepub fn from_extension<S>(ext: S) -> Option<Self>where
S: AsRef<OsStr>,
pub fn from_extension<S>(ext: S) -> Option<Self>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));
sourcepub fn from_path<P>(path: P) -> ImageResult<Self>where
P: AsRef<Path>,
pub fn from_path<P>(path: P) -> ImageResult<Self>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);
sourcepub fn from_mime_type<M>(mime_type: M) -> Option<Self>where
M: AsRef<str>,
pub fn from_mime_type<M>(mime_type: M) -> Option<Self>where M: AsRef<str>,
Return the image format specified by a MIME type.
Example
use image::ImageFormat;
let format = ImageFormat::from_mime_type("image/png").unwrap();
assert_eq!(format, ImageFormat::Png);
sourcepub fn extensions_str(self) -> &'static [&'static str]
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.
