Produces an RGB or grayscale visualization of an image. Each of the gain, bias, min, max and gamma arguments can take either a single value, which will be applied to all bands, or a list of values the same length as bands.
Usage
Returns
Image.visualize(bands, gain, bias, min, max, gamma, opacity, palette, forceRgbOutput)
Image
Argument
Type
Details
this: image
Image
The image to visualize.
bands
Object, default: null
A list of the bands to visualize. If empty, the first 3 are used.
gain
Object, default: null
The visualization gain(s) to use.
bias
Object, default: null
The visualization bias(es) to use.
min
Object, default: null
The value(s) to map to RGB8 value 0.
max
Object, default: null
The value(s) to map to RGB8 value 255.
gamma
Object, default: null
The gamma correction factor(s) to use.
opacity
Number, default: null
The opacity scaling factor to use.
palette
Object, default: null
The color palette to use. List of CSS color identifiers or hexadecimal color strings (e.g., ['red', '00FF00', 'blueviolet']).
forceRgbOutput
Boolean, default: false
Whether to produce RGB output even for single-band inputs.
