Golang在Window环境使用Imagick7

安装msys2

• 下载安装 https://www.msys2.org/
• 在msys2执行以下命令

pacman -Syuu
pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-pkg-config
pacman -S mingw-w64-x86_64-zlib
pacman -S mingw-w64-x86_64-imagemagick

配置环境变量

set PATH=c:\msys64\mingw64\bin;%PATH%
set PKG_CONFIG_PATH=c:\msys64\mingw64\lib\pkgconfig
set MAGICK_CODER_MODULE_PATH=c:\msys64\mingw64\lib\ImageMagick-7.0.6\modules-Q16HDRI\coders

• msys64需根据安装地址修改c:\msys64\mingw64
• ImageMagick-7.0.6需根据安装版本确认修改

扩展编译

go build gopkg.in/gographics/imagick.v3/imagick

pkg-config --cflags --libs MagickWand

go get -u gopkg.in/gographics/imagick.v3/imagick

示例代码

package main

import "gopkg.in/gographics/imagick.v3/imagick"

func main() {
	imagick.Initialize()
	defer imagick.Terminate()

	mw1 := imagick.NewMagickWand()
	defer mw1.Destroy()
	
	mw1.ReadImage("./human.jpg")
	mw1.ResizeImage(100, 100, imagick.FILTER_LANCZOS)
	mw1.WriteImage("./human_resize.jpg")
}
