# RGB terminal
Have you had enough of the same 16 colors in your terminal?
Welcome to a new world. A new world where colors are plentyful.
A world in 256 colors.
![so many colors!](https://cloud.githubusercontent.com/assets/1189716/3563662/15e67546-0a49-11e4-871e-47e694d08981.png)
# Usage
```go
// pick a color
var r, g, b uint8
r, g, b = 252, 255, 43
// choose a word
word := "=)"
// colorize it!
coloredWord := rgbterm.FgString(word, r, g, b)
// print it!
fmt.Println("Oh!", coloredWord, "hello!")
```
> ![screen shot 2014-07-13 at 0 56 44](https://cloud.githubusercontent.com/assets/1189716/3563695/54e7f048-0a4a-11e4-8b53-613761c6c4e2.png)
Also, to be correct: there are 216 colors and 16 grey scales. For more details, [Xterm][xterm-wiki].

# This package is no longer being updated! Please look for alternatives if that bothers you.
Resize
======
Image resizing for the [Go programming language](http://golang.org) with common interpolation methods.
[![Build Status](https://travis-ci.org/nfnt/resize.svg)](https://travis-ci.org/nfnt/resize)
Installation
------------
```bash
$ go get github.com/nfnt/resize
```
It's that easy!
Usage
-----
This package needs at least Go 1.1. Import package with
```go
import "github.com/nfnt/resize"
```
The resize package provides 2 functions:
* `resize.Resize` creates a scaled image with new dimensions (`width`, `height`) using the interpolation function `interp`.
If either `width` or `height` is set to 0, it will be set to an aspect ratio preserving value.
* `resize.Thumbnail` downscales an image preserving its aspect ratio to the maximum dimensions (`maxWidth`, `maxHeight`).
It will return the original image if original sizes are smaller than the provided dimensions.
```go
resize.Resize(width, height uint, img image.Image, interp resize.InterpolationFunction) image.Image
resize.Thumbnail(maxWidth, maxHeight uint, img image.Image, interp resize.InterpolationFunction) image.Image
```
The provided interpolation functions are (from fast to slow execution time)
- `NearestNeighbor`: [Nearest-neighbor interpolation](http://en.wikipedia.org/wiki/Nearest-neighbor_interpolation)
- `Bilinear`: [Bilinear interpolation](http://en.wikipedia.org/wiki/Bilinear_interpolation)
- `Bicubic`: [Bicubic interpolation](http://en.wikipedia.org/wiki/Bicubic_interpolation)
- `MitchellNetravali`: [Mitchell-Netravali interpolation](http://dl.acm.org/citation.cfm?id=378514)
- `Lanczos2`: [Lanczos resampling](http://en.wikipedia.org/wiki/Lanczos_resampling) with a=2
- `Lanczos3`: [Lanczos resampling](http://en.wikipedia.org/wiki/Lanczos_resampling) with a=3
Which of these methods gives the best results depends on your use case.
Sample usage:
```go
package main
import (
"github.com/nfnt/resize"
"image/jpeg"
"log"
"os"
)
func main() {
// open "test.jpg"
file, err := os.Open("test.jpg")
if err != nil {
log.Fatal(err)
}
// decode jpeg into image.Image
img, err := jpeg.Decode(file)
if err != nil {
log.Fatal(err)
}
file.Close()
// resize to width 1000 using Lanczos resampling
// and preserve aspect ratio
m := resize.Resize(1000, 0, img, resize.Lanczos3)
out, err := os.Create("test_resized.jpg")
if err != nil {
log.Fatal(err)
}
defer out.Close()
// write new image to file
jpeg.Encode(out, m, nil)
}
```
Caveats
-------
* Optimized access routines are used for `image.RGBA`, `image.NRGBA`, `image.RGBA64`, `image.NRGBA64`, `image.YCbCr`, `image.Gray`, and `image.Gray16` types. All other image types are accessed in a generic way that will result in slow processing speed.
* JPEG images are stored in `image.YCbCr`. This image format stores data in a way that will decrease processing speed. A resize may be up to 2 times slower than with `image.RGBA`.
Downsizing Samples
-------
Downsizing is not as simple as it might look like. Images have to be filtered before they are scaled down, otherwise aliasing might occur.
Filtering is highly subjective: Applying too much will blur the whole image, too little will make aliasing become apparent.
Resize tries to provide sane defaults that should suffice in most cases.

Image2ASCII is a library that converts images into ASCII images and provides command-line tools for easy use.
![demo](https://github.com/qeesung/image2ascii/blob/master/docs/images/lufei.gif?raw=true)
## Installation
```bash
go get 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 (default "docs/images/lufei.jpg")
-g int
Expected image height, -1 for image default height (default -1)
-i Reversed the ascii when output to the terminal
-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)
-t Stretch the picture to overspread the screen
-w int
Expected image width, -1 for image default width (default -1)
```
convert the image fit the screen(default is true)
```bash
image2ascii -f docs/images/pikaqiu2.jpg
```
![demo](https://github.com/qeesung/image2ascii/blob/master/docs/images/pikaqiu_s.gif?raw=true)
convert the image to ascii image with fixed width and height
```bash
# width: 100
# height: 30
image2ascii -f docs/images/baozou.jpg -w 100 -g 30
```
![demo](https://github.com/qeesung/image2ascii/blob/master/docs/images/baozou.gif?raw=true)
convert the image to ascii image by ratio
```bash
# ratio: 0.3
# width: imageWidth * 0.3
# height: imageHeight * 0.3
image2ascii -f docs/images/pikaqiu.jpg -r 0.3
```
![demo](https://github.com/qeesung/image2ascii/blob/master/docs/images/pikaqiu.gif?raw=true)
convert the image to stretch the screen
```bash
image2ascii -f docs/images/long.jpg -t
```
![demo](https://github.com/qeesung/image2ascii/blob/master/docs/images/long.gif?raw=true)
convert the image without the color
```bash
image2ascii -f docs/images/lufei.jpg -s -c=false
```
convert the image disable fit the screen
```bash
image2ascii -f docs/images/lufei.jpg -s=false
```
convert the image reverse the chars
```bash
image2ascii -f docs/images/lufei.jpg -i
```
## Library usage
```golang
package main
import (
"fmt"
"github.com/qeesung/image2ascii/convert"
_ "image/jpeg"
_ "image/png"
)
func main() {
// Create convert options
convertOptions := convert.DefaultOptions
convertOptions.FixedWidth = 100
convertOptions.FixedHeight = 40
// Create the image converter
converter := convert.NewImageConverter()
fmt.Print(converter.ImageFile2ASCIIString(imageFilename, &convertOptions))
}
```
convert options
```golang
type Options struct {
Ratio float64 // convert ratio
FixedWidth int // convert the image width fixed width
FixedHeight int // convert the image width fixed height
FitScreen bool // only work on terminal, fit the terminal height or width
StretchedScreen bool // only work on terminal, stretch the width and heigh to overspread the terminal screen
Colored bool // only work on terminal, output ascii with color
Reversed bool // if reverse the ascii pixels
}
```
supported convert function
```golang
type Converter interface {
// convert a image object to ascii matrix
Image2ASCIIMatrix(image image.Image, imageConvertOptions *Options) []string
// convert a image object to ascii matrix and then join the matrix to a string
Image2ASCIIString(image image.Image, options *Options) string
// convert a image object by input a string to ascii matrix
ImageFile2ASCIIMatrix(imageFilename string, option *Options) []string
// convert a image object by input a string to ascii matrix then join the matrix to a string
ImageFile2ASCIIString(imageFilename string, option *Options) string
}
```
