Node.js GM segment() Function Last Updated : 28 Apr, 2025 Comments Improve Suggest changes Like Article Like Report The segment() function is an inbuilt function in the GraphicsMagick library which is used to segment an image by analyzing the histograms of the color components and identifying units that are homogeneous with the fuzzy c-means technique. The function returns the true value on success. Syntax: threshold( cluster threshold, smoothing threshold ) Parameters: This function accepts two parameters as mentioned above and described below: cluster threshold: This parameter is used to specify the value of the cluster threshold.smoothing threshold: This parameter is used to specify the value of the smoothing threshold. Return Value: This function returns the GraphicsMagick object. Example 1: JavaScript // Include gm library const gm = require('gm'); //Import the image gm(600, 300, 'white') // set the color for the stroke .stroke("green", 3) // Set the font .font("Helvetica.ttf", 60) //Call to drawText Function .drawText(100, 280, "GeeksforGeeks!") // Invoke segment function .segment(1, 0.1) // Process and write the image .write("segment1.png", function (err) { if (!err) console.log('done'); }); Output: Example 2: JavaScript // Include gm library const gm = require('gm'); // Import the image gm('1.png') // Invoke segment function with 2, 0.2 .segment(2, 0.2) // Process and Write the image .write("segment1.png", function (err) { if (!err) console.log('done'); }); Output: Reference: http://www.graphicsmagick.org/GraphicsMagick.html#details-rotatehttps://www.npmjs.com/package/gm Comment More infoAdvertise with us Next Article Node.js GM segment() Function S sarthak_ishu11 Follow Improve Article Tags : Web Technologies Node.js Image-Processing Node.js-GM Similar Reads Node.js GM shave() Function The shave() function is an inbuilt function in the GraphicsMagick library which is used to shave the image pixels from the edges which specifies the width of the region to be removed from both sides of the image and the height of the regions to be removed from top and bottom. Syntax: shave(width, h 1 min read Node.js GM sepia() Function The sepia() function is an inbuilt function in the GraphicsMagick library which is used to apply a sepia filter to an image.
