Node.js GM whitePoint() Function

Last Updated : 25 Apr, 2025

The whitePoint() function is an inbuilt function in the GraphicsMagick library which is used to make chromaticity white points. The function returns the true value of success.

Syntax:

whitePoint(x, y)

Parameters: This function accepts two parameters as mentioned above and described below:

x: This parameter is used to specify the x-coordinate of the white point.
y: This parameter is used to specify the y-coordinate of the white point.

Return Value: This function returns the GraphicsMagick object.

Example:

javascript

// Include gm library 
const gm = require('gm'); 
 
// Import the image 
gm(500, 200, 'black') 
 
// Set the color for the stroke 
.stroke("green", 3) 
 
.background('green') 
.font("Helvetica.ttf", 60) 
 
.drawText(30, 160, "GeeksforGeeks!") 
 
// Invoke whitePoint function with 
// x, y as 250, 100 respectively. 
.whitePoint(250, 100) 
 
// Process and write the image 
.write("whitePoint1.png", function (err) { 
if (!err) console.log('done'); 
});
