Ramp.Transform

Description

Name: class Tinman.Color.Ramp.Transform
Derived from: Tinman.Color.Ramp

Transforms the input coordinate of the given color ramp. Input X-coordinates are transformed as follows:

xOut = offset + scale * xIn
xIn  = (xOut - offset) / scale
     = xOut / scale - offset / scale

where xIn refers to the coordinate passed to the returned color ramp and xOut is the coordinate that is passed to this color ramp.

Fields / Required

`ramp`

Type: Tinman.Color.Ramp
Constraint: # != null

The source color ramp.

Fields / Optional

`scale`

Type: number
Constraint: # != 0
Default: 1

Scale factor to apply to input X-coordinates.

`offset`

Type: number
Default: 0

Offset value to add to scaled input X-coordinates.
