Introduction
The blit() function is an inbuilt function in Nodejs. It is used to combine two bitmap patterns. | Jimp which combines several bitmaps into one using a boolean function.
Parameters:
- src – This parameter stores the source of the image to blit.
- x – This parameter takes x position to blit the image.
- y – This parameter takes y position to blit the image.
- srcx (optional) – This parameter takes the x position from which to crop the source image.
- srcy (optional) – This parameter takes the y position from which to crop the source image.
- srcw (optional) – This parameter takes the width to which to crop the source image.
- srch (optional) – This parameter takes the height to which to crop the source image.
Input Images:
Example 1:
// npm install --save jimp // import jimp library to the environment var Jimp = require( 'jimp' );
// User-Defined Function to read the images async function main() {
const image1 = await Jimp.read( '../gfg.png' );
const image2 = await Jimp.read( '../gfg1.png' );
// call to blit function
image1.blit(image2, 20, 40)
// write image
.write( 'blit1.png' );
console.log( 'Image Processing Completed' );
} main(); |
Output:
Example 2:
// npm install --save jimp // import jimp library to the environment var Jimp = require( 'jimp' );
// User-Defined Function to read the images async function main() {
const image1 = await Jimp.read( '../gfg.png' );
const image2 = await Jimp.read( '../gfg1.png' );
// call to blit function along with optional parameters
image1.blit(image2, 20, 40, 130, 30, 440, 80);
// write image
.write( 'blit2.png' );
console.log( 'Image Processing Completed' );
} main(); |
