Example 1:
javascript
// Include gm libraryconst gm = require('gm').subClass({imageMagick: true});
// Import the imagegm('1.png')
// set the color for the stroke.stroke("#ffffff")
// Invoke Bezier function.drawBezier([30, 20], [390, 70], [140, 110], [45, 56], [98, 45], [123, 65])
// Process and write the image.write("drawBezier1.png", function (err) {
if (!err) console.log('done');
}); |
Output:
Example 2:
javascript
// Include gm libraryconst gm = require('gm');
// Import the imagegm(600, 300, 'white')
// Set the color for the stroke.stroke("green", 3)
// Set the font.font("Helvetica.ttf", 60)
// Invoke Bezier function.drawBezier([30, 20], [390, 70], [140, 110], [45, 56], [98, 45], [123, 65], [500, 250])
// Call to drawText Function.drawText(100, 280, "GeeksforGeeks!")
