}

Variants

SetGamma

set the gamma table

Set the gamma table. The file descriptor can be memory-mapped to provide the raw gamma table, which contains successive gamma ramps for the red, green and blue channels. Each gamma ramp is an array of 16-byte unsigned integers which has the same length as the gamma size.

The file descriptor data must have the same length as three times the gamma size.

Fields of SetGamma

fd: RawFd

Destroy

destroy this control

Destroys the gamma control object. If the object is still valid, this restores the original gamma tables.

This is a destructor, once sent this object cannot be used any longer.
