Expand description

transform from framebuffer to output

This describes the transform that a compositor will apply to a surface to compensate for the rotation or mirroring of an output device.

The flipped values correspond to an initial flip around a vertical axis followed by rotation.

The purpose is mainly to allow clients to render accordingly and tell the compositor, so that for fullscreen surfaces, the compositor will still be able to scan out directly from client surfaces.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Normal

no transform

_90

90 degrees counter-clockwise

_180

180 degrees counter-clockwise

_270

270 degrees counter-clockwise

Flipped

Flipped90

flip and rotate 90 degrees counter-clockwise

Flipped180

flip and rotate 180 degrees counter-clockwise

Flipped270

flip and rotate 270 degrees counter-clockwise
