func LinearPoint ¶

func LinearPoint(a, b color.Color, p float64) color.RGBA

LinearPoint takes two colors and a float64, `p`, representing a position between them. It returns the colour represented by position `p` assuming a linear interpolation between the two colors. The position `p` is capped to the range `0 <= p <= 1`.

a := color.RGBA{0xFF, 0x00, 0x00, 0xFF}
b := color.RGBA{0x00, 0x00, 0xFF, 0xFF}

c := LinearPoint(a, b, 0.5)
fmt.Printf("#%02x%02x%02x @ %02x", c.R, c.G, c.B, c.A)

Output:

#80007f @ ff
