Try to write ImageMagick with gobinding

I use the system is ubutu12.04, previously because the system apt installation missing library files, I use the tar download make install installation, here to a library file has been added to the tar package


OK, then go to the official docs and GitHub and execute them sequentially

sudo apt-get install libmagickwand-dev

Check if Pkg-config is able to find the right ImageMagick include and Libs:

pkg-config --cflags --libs MagickWand

Then go get it:

go get github.com/gographics/imagick/imagick  //默认安装在第一个gopath的文件夹下
I simply wrote a demo.

Package Main

Import (

Func Main () {
Imagick. Initialize ()
Defer Imagick. Terminate ()
MW: = Imagick. Newmagickwand ()
Defer MW. Destroy ()
Owl Readimage ("/home/qboxtest/qbox/image/fop_ncgo/src/qbox.us/fop/imgave/samples/sample.jpg")

Height: = Int (MW). Getimageheight ())
Width: = Int (MW). Getimagewidth ())
println (height, width)
PW: = Imagick. Newpixelwand ()
Defer PW. Destroy ()
PW=MW. Getimagepixelcolor (2, 2)//Congratulations here on the problem, after the reason, should be and the TAR package provided library file conflict, compile no problem, the execution of the rest of the dish
Fmt. Println ("xxxx", PW)

r: = pw. Getred ()
G: = pw. Getgreen ()
B: = pw. GetBlue ()
A: = PW. Getalpha ()
println ("xxxxxxx", R, G, B, a)

RGB: = Int (Ten) <<16 | Int (one) <<8 | Int (12)
Fmt. Printf ("0x%06x", RGB)

Next i uninstalled the ImageMagick of my own installation and went through the process again, regardless of whether I installed ImageMagick with apt, always error

# command-line-arguments
/usr/bin/ld:cannot find-lmagickwand-6.q16
/usr/bin/ld:cannot find-lmagickcore-6.q16
Collect2:ld returned 1 exit status

The corresponding library files are not found in Usr/lib and Usr/local/lib, there is no path to install, and you cannot find

With Dpkg-s magic* view, found that the ubuntu12.04 comes with the library is 6.6.9 version, but gobinding requires more than 6.8

[Email protected]:~/desktop$ dpkg-s magic*

At this time to compile and found that the compilation but

# Github.com/gographics/imagick/imagick
37:error: ' Flattenalphachannel ' undeclared (first use of this function)
37:error: ' Removealphachannel ' undeclared (first use of this function)
