Node.js GM shade() Function Last Updated : 28 Apr, 2025 Summarize Comments Improve Suggest changes Share Like Article Like Report The shade() function is an inbuilt function in the GraphicsMagick library which is used to shade the image using a distant light source. The function returns the true value of success. Syntax: shade( azimuthal angle, elevation angle ) Parameters: This function accepts two parameters as mentioned above and described below: azimuthal angle: This parameter stores the value of the azimuthal angle.elevation angle: This parameter stores the value of the elevation angle. Return Value: This function returns the GraphicsMagick object with an image added. Original Image: Example: javascript // Include gm library const gm = require('gm'); // Import the image gm('gfg.png') // Set stroke color .stroke("#fe1232") // Set fill color .fill("#1200ff") // Draw Rectangle using drawRectangle function .drawRectangle(10, 2, 130, 30, 1, 2) // Invoke shadefunction with azimuthal // as 45 and elevation angle as 90 .shade(45, 90) // Process and Write the image .write("shade1.png", function (err) { if (!err) console.log('done'); }); Output: Reference: http://www.graphicsmagick.org/GraphicsMagick.html#details-shadehttps://www.npmjs.com/package/gm Comment More infoAdvertise with us Next Article Node.js GM scale() Function S sarthak_ishu11 Follow Improve Article Tags : Web Technologies Node.js Image-Processing NodeJS-function Node.js-GM +1 More 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 sharpen() Function The sharpen() function is an inbuilt function in the GraphicsMagick library which is used to sharpen the image.
