Implementations

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));

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);

Return if the ImageFormat can be decoded by the lib.

Return if the ImageFormat can be encoded by the lib.

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.
