Functions

func Show

func Show(f func(dx, dy int) [][]uint8)

Show displays a picture defined by the function f when executed on the Go Playground.

f should return a slice of length dy, each element of which is a slice of dx 8-bit unsigned int. The integers are interpreted as bluescale values, where the value 0 means full blue, and the value 255 means full white.

Example
package main

import (
	"golang.org/x/tour/pic"
)

func main() {
	f := func(dx, dy int) [][]uint8 {
		ss := make([][]uint8, dy)
		for y := 0; y < dy; y++ {
			s := make([]uint8, dx)
			for x := 0; x < dx; x++ {
				s[x] = uint8((x + y) / 2)
			}
			ss[y] = s
		}
		return ss
	}

	pic.Show(f)

}
