ee.Image.visualize
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. |
