Node.js GM write() Function

Last Updated : 25 Apr, 2025

The write() function is an inbuilt function in the GraphicsMagick library which is used to write an image to a file. If a file already exists, then it will be overwritten. The function returns the true value of success.

Syntax:

write( filename )

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

filename: This parameter is used to specify the name of the file.

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) 

// Invoke drawRectangle function with 
// x0: 10, y0: 100, x1:260, y1:210 
.drawRectangle(10, 100, 260, 210) 

// Invoke drawText in order to 
// name the box as 1 
.drawText(150, 170, "1") 

// Invoke drawrectangle function with 
// x0: 260, y0:100, x1: 350, y1: 210 
.drawRectangle(260, 100, 350, 210) 

// Invoke drawText in order to 
// name the box as 2 
.drawText(300, 170, "2") 

// Call to drawText Function 
.drawText(100, 280, "GeeksforGeeks!") 

// Process and write the image 
.write("drawRectangle1.png", function (err) { 
    if (!err) console.log('done'); 
});

Output:

Example 2: Overwriting the file.

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) 

// Invoke drawRectangle function with 
// x0: 10, y0: 100, x1:260, y1:210, 
// wc: 40, wh: 40 
.drawRectangle(10, 100, 260, 210, 40, 40) 

// Invoke drawText in order to 
// name the box as 1 
.drawText(150, 170, "1") 

// Invoke drawrectangle function with 
// x0: 260, y0:100, x1: 350, y1: 210, 
// wc: 80, wh: 80 
.drawRectangle(260, 100, 350, 210, 80, 80) 

// Invoke drawText in order to 
// name the box as 2 
.drawText(300, 170, "2") 

// Call to drawText Function 
.drawText(100, 280, "GeeksforGeeks!") 

// Process and write the image 
.write("drawRectangle1.png", function (err) { 
    if (!err) console.log('done'); 
});
