Variants

GammaSize

size of gamma ramps

Advertise the size of each gamma ramp.

This event is sent immediately when the gamma control object is created.

Fields of GammaSize

size: u32

Failed

object no longer valid

This event indicates that the gamma control is no longer valid. This can happen for a number of reasons, including:

• The output doesn't support gamma tables
• Setting the gamma tables failed
• Another client already has exclusive gamma control for this output
• The compositor has transfered gamma control to another client

Upon receiving this event, the client should destroy this object.
