  • 3 Methods of Automatic Image Generation: Image Generation API, Libraries, and Puppeteer Screenshots
    3 projects | dev.to | 19 Aug 2022
    The next option is to use an image generation library and implement the full solution yourself. Libraries like ImageMagick, Python Imaging Library (PIL), and Sharp in Node.js provide an API for image processing. Such libraries are typically used for resizing, cropping, changing image format, compressing images, etc.

    Using sharp we can easily apply many common transformations to any image, including watermarking! Vercel's Edge network helps ensure we cache the result and a slight tweak to MicroFrontendRegistry via the MicroFrontendRegistry.url() method will give us a URL to request the image transformation so that it can be leveraged in img tags as well.

    For writing text on images (like PNG or JPEG) I would use jimp or sharp. jimp is easier if all you want to do is add text on image with custom font.

    If you have some Node and command line experience, check out Sharp. It’s an amazingly powerful image optimization tool used as the backbone of many image optimization services/apps.
  • Learn How to Use Lambda Layers by Building an Image Resize Function Using Sharp
    2 projects | dev.to | 4 May 2022
    Lambda Layer is a true gem in the Lambda function realm. It provides a convenient way to package your libraries and other dependencies that can be used with the Lambda functions. Our open-source project, Webiny which has 50k+ downloads and 5.5k stars on GitHub uses Lambda layers. It helps us reduce our Lambda function size by 12 MB and enable us to share the image processing library sharp across all the Webiny deployments.

  • What is AVIF?
    6 projects | dev.to | 26 Apr 2022
    The Alliance for Open Media's AVIF encoding and decoding library is also in a Github repo. Sharp, a Node module, has AVIF support. To make AVIF images, you can use avif.io, Squoosh, and the Squoosh command line tool aimed at supporting Node.js apps. GIMP and Paint.net support AVIF and there are Photoshop plugins. Mac has no plans to support AVIF, but you can easily install a codec plugin on Windows 10 for native support.
