Pixel.Adjust

Description

Name: class Tinman.Pixel.Adjust
Derived from: Pixel

Adjust the brightness and saturation of the target pixels.

If slopes have been computed (see Slopes), the adjustment factors for each pixel are computed as follows:

90° >= slope >= 0°
b' = slope / 90 * b
s' = slope / 90 * s

where slope is the slope angle of the pixel, b is the Pixel.Adjust.brightness field, s is the Pixel.Adjust.saturation field. The values b' and s' are then used for adjusting the pixel color.

Fields / Required

`source`

Type: Pixel
Constraint: # != null

The input buffer.

Fields / Optional

`brightness`

Type: number
Constraint: # >= -1000 && # <= 1000
Default: 0

The adjustment factor for color brightness (0 means no change).

`saturation`

Type: number
Constraint: # >= -1000 && # <= 1000
Default: 0

The adjustment factor for color saturation (0 means no change).

`slope`

Type: bool
Default: false

Modulate color adjustment factors with terrain slope?
