Types ¶
type Continuous ¶
A Continuous palette is a function from [0, 1] to colors. It may be sequential, diverging, or circular.
var Viridis Continuous
Viridis is a continuous sequential color map that is perceptually uniform, colorblind-friendly, and converts well to grayscale. It goes from black to blue to green to yellow.
Viridis was developed by Stéfan van der Walt, Nathaniel Smith, and Eric Firing as the default colormap for Matplotlib 2.0. It is available under a CC0 (no rights reserved) license.
type RGBGradient ¶
type RGBGradient struct {
// Colors is the sequence of colors to interpolate between.
// Interpolation assumes the colors are sRGB values.
Colors []color.RGBA
// Stops is an optional sequence of stop positions. It may be
// nil, in which case Colors are evenly spaced on the interval
// [0, 1]. Otherwise, it must be a slice with the same length
// as Colors and must be in ascending order.
Stops []float64
}
RGBGradient is a Continuous palette that interpolates between a sequence of colors.
