Merge 2 images with node.js?

Question

I want to merge 2 images using node.js. Or rather, i want to place one smaller image on cordinates x,y on a larger image. Even more precise: I have an image of glasses, and an image of a face and i want to put the glasses on the face. I did some googling, and found some image manipulating libraries, but none seem to be able to merge images.

Answer 1

You might need this: https://github.com/zhangyuanwei/node-images

Cross-platform image decoder(png/jpeg/gif) and encoder(png/jpeg) for Nodejs

images("big.jpg").draw(images("small.jpg"), 10, 10).save("output.jpg");

I do no have enough reputation to add a comment, or else I would to Schmidko's answer.

Sharp works well, however, overlayWith is deprecated and you instead need to use composite. See below:

sharp(path + 'example.jpg')
       .composite([{input: path + 'logo.png', gravity: 'southeast' }])
       .toFile(path + 'output.png');

If you would like to center the image being overlayed: gravity: 'centre'
