VisualizationOptions

  • Learn how to generate an 8-bit RGB visualization of your data.

  • Configure visualization parameters using a JSON representation with fields for ranges, palette colors, gamma, and opacity.

  • Specify data ranges to map to 0-255 in the output image, with options for individual or all bands.

  • Apply CSS-style RGB color palettes for single-band visualizations.

  • Adjust the image using gamma correction and opacity factors.

Fields
ranges[]

object (DoubleRange)

If present, specifies the range of data values to visualize. This range of values will be mapped to 0-255 (black to white) in the resulting image, and values outside this range will be clamped. May specify as one range for each band being visualized or else a single range to be applied to all bands.
paletteColors[]

string

If present, specifies sequence of CSS-style RGB color identifiers to apply as a color palette. Only allowed when visualizing a single data band.
gamma

number

If present, specifies an overall gamma correction factor to apply to the image.
opacity

number

If present, specifies an overall opacity factor to apply to the image, in the range 0.0 to 1.0.
