DissolveToColorStochastically

Returns a pixmap with each pixel unchanged or set to a given colour with a given probability.

Syntax

• DissolveToColorStochastically(pm, c[, p])

  • pm is a pixmap

  • c is a colour

  • p is a number in [0, 1]

• DissolveToColorRegularly(pm, f[, p])

  • pm is a pixmap

  • f is a colour function in two integer variables

  • p is a number in [0, 1]

Description

DissolveToColorStochastically(pm, c, p) returns pm with each pixel either unaltered or set to c with the probability of the latter being p. If omitted, p defaults to 0.5.

The overload with a function instead of a colour will use f(x, y) as the colour at pixel (x, y).

Examples

DissolveToColorStochastically(ExampleData("rabbit"), (x, y) ↦ hsv(x + y, 1, 1), 0.25)
