The color tone class. Each component is handled with a floating point value (Float).

Superclass

Class Method

Tone.new(red, green, blue[, gray])

Creates a Tone object. If gray is omitted, it is assumed at 0.

Method

set(red, green, blue[, gray])

Sets all components at once.

Properties

red

The red balance adjustment value (-255 to 255). Values out of range are automatically corrected.

green

The green balance adjustment value (-255 to 255). Values out of range are automatically corrected.

blue

The blue balance adjustment value (-255 to 255). Values out of range are automatically corrected.

gray

When this value is not 0, processing time is significantly longer than when using tone balance adjustment values alone.
