Create RGB image from class probability/fraction layer¶
Create an RGB image from a class fraction layer or class probability layer.The RGB pixel color of a single pixel is given by the weighted mean of the given category colors.The weights are given by class fractions/probabilities (i.e. values between 0 and 1). For example, pure pixels with cover fractions of 1 appear in its pure category color. A mixed-pixel with a 50% fractions in two categories colored in red and green,appears in a dull yellow ( 0.5 x (255, 0, 0) + 0.5 x (0, 255, 0) = (127, 127, 0) ).
Parameters
- Class probability/fraction layer [raster]
- A class fraction layer or class probability layer used as weights for calculating final pixel colors.
- Colors [string]
- Comma separated list of hex-color strings (e.g. ‘#FF0000’ for red) representing (pure) category colors, one color for each band in the given class probability/fraction layer. If not specified, colors have to be specified by a categorized layer (Colors from categorized layer).
- Colors from categorized layer [layer]
- A categorized layer with (pure) category colors, one category for each band in the given class probability/fraction layer. If not specified, colors have to be specified by list (Colors).
Outputs
- Output RGB image [rasterDestination]
- Raster file destination.
