Convert image to ASCII
## Installation
```bash
go get https://github.com/qeesung/image2ascii
```
## CLI usage
```bash
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
```bash
# width: 100
# height: 30
image2ascii -f example/images/lufei.jpg -w 100 -g 30
```
convert the image to ascii image by ratio
```bash
# ratio: 0.3
# width: imageWidth * 0.3
# height: imageHeight * 0.3
image2ascii -f example/images/lufei.jpg -r 0.3
```
convert the image to ascii fit the screen
```bash
image2ascii -f example/images/lufei.jpg -s
```
convert the image without the color
```bash
image2ascii -f example/images/lufei.jpg -s -c=false
```
convert the image disable fit the screen
```bash
image2ascii -f example/images/lufei.jpg -s=false
```
## Library usage
```golang
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
```golang
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
```golang
// convert a image object to ascii matrix
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 {}
```
## Sample outputs
