Node.js GM Shave() Function

The shave() function is a method provided by the GraphicsMagick (abbreviated as GM) library for Node.js. It is used to trim the edges of an image to remove any unwanted whitespace or border.

Syntax:

gm('/path/to/image.png')
    .shave(width, height)
    .write('/path/to/trimmed-image.png', function (err) {
        if (!err) console.log('Image has been trimmed!');
    });

Parameters:

• width (required): The width in pixels of the area to shave from each side of the image.
• height (required): The height in pixels of the area to shave from each side of the image.

Example:

The following example code demonstrates how to use the shave() function to trim an image:

const gm = require('gm');

gm('/path/to/image.png')
    .shave(50, 50)
    .write('/path/to/trimmed-image.png', function (err) {
        if (!err) console.log('Image has been trimmed!');
    });

In this example, we're shaving 50 pixels from each side of the image, which will remove a 50-pixel border all around the image.

Additional Options:

The shave() function also supports additional options such as crop, gravity, color, and bordercolor. These options allow you to further customize the trimming behavior.

For more information on these options, please refer to the GraphicsMagick documentation.
