Nodejs image crop by coordinates

问题

Is there is way where we can give x, y coordinates while cropoing image.

Currently what i am using is Imagemagick

im.crop({
    srcPath: upload_path+media_file_name,
    dstPath: upload_path+"thumb_"+media_file_name,
    width: 350,
    height: 210,
    quality: 1,
    gravity: 'Center'
}, function(err, stdout, stderr){

};

This code is working but i haven't got luck with x, y coordinates. The following input i want to use for image cropping

height:360
width:360
x:180
y:300

回答1:

I don't speak node, but can you use the raw interface? It'll look something like

im.convert(['inputimage.jpg','-crop','350x200+x+y','output.jpg'],
   function(...)

put in your own numbers for x and y.
