Imgedit is a package that performs image processing such as resizing and trimming.

Overview

Imgedit is a package that performs image processing such as resizing and trimming available on both CLI and GUI.

Features

• resize
• trim
• tile (lay down images)
• reverse (vertical, horizon)
• grayscale
• add string
• filter (gray, sepia)
• interactive file format conversion (png, jpeg, gif)

resize	trim	tile
reverse horizon	reverse vertical	add string
filter gray	filter sepia

Usage (Package)

$ go get github.com/icemint0828/imgedit@v1.6.0

An example with file conversion is as follows.

package main

import (
    "github.com/icemint0828/imgedit"
)

func main() {
    fc, _, err := imgedit.NewFileConverter("srcImage.png")
    if err != nil {
        panic(err)
    }
    fc.Filter(imgedit.GrayModel)
    err = fc.SaveAs("dstImage.png", imgedit.Png)
    if err != nil {
        panic(err)
    }
}

It can also work with just convert bytes through io.Writer and io.Reader.

package main

import (
	"bytes"
	"os"

	"github.com/icemint0828/imgedit"
)

func main() {
	srcFile, err := os.Open("srcImage.png")
	if err != nil {
		panic(err)
	}
	defer srcFile.Close()

	bc, _, err := imgedit.NewByteConverter(srcFile)
	bc.ResizeRatio(0.5)

	buffer := bytes.NewBuffer([]byte{})
	_ = bc.WriteAs(buffer, imgedit.Jpeg)

	dstFile, err := os.Create("dstImage.png")
	if err != nil {
		panic(err)
	}
	defer dstFile.Close()

	_, _ = buffer.WriteTo(dstFile)
}

It can also work with just convert image.

package main

import (
    "image/png"
    "os"

    "github.com/icemint0828/imgedit"
)

func main() {
    srcFile, err := os.Open("srcImage.png")
    if err != nil {
        panic(err)
    }
    defer srcFile.Close()
    srcImage, err := png.Decode(srcFile)
    if err != nil {
        panic(err)
    }

    c := imgedit.NewConverter(srcImage)
    c.Resize(500, 500)
    dstImage := c.Convert()

    dstFile, err := os.Create("dstImage.png")
    if err != nil {
        panic(err)
    }
    defer dstFile.Close()
    err = png.Encode(dstFile, dstImage)
    if err != nil {
        panic(err)
    }
}

Usage (CLI)

You can download the executable file from the link below.

• Windows

• Linux

• mac OS

Or if you can use brew on mac OS.

$ brew install icemint0828/tap/imgedit

For more information, please use the help command:

$ imgedit -help

Usage (CLI on docker)

You can also run the CLI on docker. This procedure can only convert files under the current working directory(WD).

$ docker run --rm -e WD=$(pwd) -v $(pwd):/mnt ghcr.io/icemint0828/imgedit:latest filter srcImage.png -mode gray

For more information, please use the help command:

$ docker run --rm -e WD=$(pwd) -v $(pwd):/mnt ghcr.io/icemint0828/imgedit:latest -help

Usage (GUI)

You can also use a sample GUI tool that is created with WASM by this package.
