Functions

func AsciiArt

func AsciiArt(r rune) rune

AsciiArt converts the rune pixel of an image (usually '0','1' or '2') into a character more suitable to be rendered as ascii art.

func MergePixels

func MergePixels(pixels ...rune) rune

MergePixels merges the pixels of a layer into a single one

func OccurrencesInLayer

func OccurrencesInLayer(layer string, pixel rune) int

OccurrencesInLayer counts how many of a given pixels are in a layer/image

Types

type Solver

type Solver struct {
	Layers []string
}

Solver implements the puzzle.Solver interface for the puzzle for day 8
