Expand description

Describes the transformations to be applied to the image. Compatible with Exif orientation.

Orientation is specified in the file’s metadata, and is often written by cameras.

You can apply it to an image via DynamicImage::apply_orientation.

Variants§

§

NoTransforms

Do not perform any transformations.

§

Rotate90

Rotate by 90 degrees clockwise.

§

Rotate180

Rotate by 180 degrees. Can be performed in-place.

§

Rotate270

Rotate by 270 degrees clockwise. Equivalent to rotating by 90 degrees counter-clockwise.

§

FlipHorizontal

Flip horizontally. Can be performed in-place.

§

FlipVertical

Flip vertically. Can be performed in-place.

§

Rotate90FlipH

Rotate by 90 degrees clockwise and flip horizontally.

§

Rotate270FlipH

Rotate by 270 degrees clockwise and flip horizontally.
