DefaultOptions that contains the default pixels

Types

type CharPixel

type CharPixel struct {
	Char byte
	R    uint8
	G    uint8
	B    uint8
	A    uint8
}

CharPixel is converted pixel ascii

type Options

type Options struct {
	Pixels   []byte
	Reversed bool
	Colored  bool
}

Options convert pixel to raw char

func NewOptions

func NewOptions() Options

NewOptions create a new convert option

type PixelASCIIConverter

type PixelASCIIConverter struct {
}

PixelASCIIConverter responsible for pixel ascii conversion

func (PixelASCIIConverter) ConvertPixelToASCII

func (converter PixelASCIIConverter) ConvertPixelToASCII(pixel color.Color, options *Options) string

ConvertPixelToASCII converts a pixel to a ASCII char string

Example

ExampleConvertPixelToASCII is a example convert pixel to ascii char

converter := NewPixelConverter()
// Create the pixel
r, g, b, a := uint8(255), uint8(255), uint8(255), uint8(255)
pixel := color.RGBA{
	R: r,
	G: g,
	B: b,
	A: a,
}

// Create the convert options
defaultOptions := NewOptions()
defaultOptions.Colored = false
convertedChar := converter.ConvertPixelToASCII(pixel, &defaultOptions)
fmt.Println(convertedChar)

Output:
