ee.Image.visualize

  • The function visualizes an image as RGB or grayscale, with optional arguments for adjusting gain, bias, min, max, and gamma for all bands or individually.

  • The usage requires an Image object and accepts parameters like bands, gain, bias, min, max, gamma, opacity, palette, and forceRgbOutput to control the visualization.

  • The arguments gain, bias, min, max, and gamma can accept a single value or a list of values corresponding to the number of bands being visualized.

 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.

UsageReturns
Image.visualize(bands, gain, bias, min, max, gamma, opacity, palette, forceRgbOutput)Image
