Image2ASCII is a library that converts images into ASCII images and provides command-line tools for easy use.

Installation

go get github.com/qeesung/image2ascii

CLI usage

image2ascii version: image2ascii/1.0.0
>> HomePage: https://github.com/qeesung/image2ascii
>> Issue   : https://github.com/qeesung/image2ascii/issues
>> Author  : qeesung
Usage: image2ascii [-s] -f <filename> -r <ratio> -w <width> -g <height>

Options:
  -c    Colored the ascii when output to the terminal (default true)
  -f string
        Image filename to be convert
  -g int
        Expected image height, -1 for image default height (default -1)
  -r float
        Ratio to scale the image, ignored when use -w or -g (default 1)
  -s    Fit the terminal screen, ignored when use -w, -g, -r (default true)
  -w int
        Expected image width, -1 for image default width (default -1)

convert the image to ascii image with fixed width and height

# width: 100
# height: 30
image2ascii -f example/images/baozou.jpg -w 100 -g 30

convert the image to ascii image by ratio

# ratio: 0.3
# width: imageWidth * 0.3
# height: imageHeight * 0.3
image2ascii -f example/images/pikaqiu.jpg -r 0.3

convert the image to ascii fit the screen

image2ascii -f example/images/lufei.jpg -s

convert the image without the color

image2ascii -f example/images/lufei.jpg -s -c=false

convert the image disable fit the screen

image2ascii -f example/images/lufei.jpg -s=false

Library usage

package main

import (
	"fmt"
	"github.com/qeesung/image2ascii/convert"
	_ "image/jpeg"
	_ "image/png"
)

func main() {
	fmt.Print(convert.ImageFile2ASCIIString("example/images/baozou.jpg", &convert.Options{
		Ratio: 0.5,
	}))
}

convert options

type Options struct {
	Ratio          float64 .       // Scale Ratio
	ExpectedWidth  int             // Convert the image with fixed width
	ExpectedHeight int             // Convert the image with fixed height
	FitScreen      bool            // Scale the image to fit the tereminal screen
	Colored bool                   // if convert the image to colored ascii
}

supported convert function

func Image2ASCIIMatrix(image image.Image, imageConvertOptions *Options) []string {}

// convert a image object to ascii matrix and then join the matrix to a string
func Image2ASCIIString(image image.Image, options *Options) string {}

// convert a image object by input a string to ascii matrix then join the matrix to a string
func ImageFile2ASCIIString(imageFilename string, option *Options) string {}
