Question:

I am trying to x y coordinates of blobs in an image.

Following suggestions from this question:<a href="https://stackoverflow.com/questions/14377463/connected-component-labeling-with-imagemagick" rel="nofollow">Connected-component labeling with ImageMagick</a>

I have this piece of code.

The end result correctly highlights the blobs.

However, I am unable to get the "verbose" output programmatically. I need the x y coordinates. AM I missing something?

gm('difference.png') .out('-colorspace') .out('gray') .out('-threshold') .out('90%') .out('-define') .out('connected-components:verbose=true') .out('-connected-components') .out('4') .out('-auto-level') .write("out.png", function(err){ console.log(err); //how to get the verbose output about the blob positions?? });`enter code here`

I found the way to get the output from the gm operations

gm(imagePath) .out('-define') .out('connected-components:verbose=true') .out('-connected-components') .out('4') .out('-auto-level') .write('out.png', function(err, stdout){ //details in stdout });
