ImageKit: Adding text and gradients with Layers API

Demo summary

The presenter demonstrates using the Layers API to programmatically add gradients and dynamic text overlays on top of a base image via URL parameters.

Step-by-step

  1. Identify the base image URL
  2. Append the layers API parameters to the URL to define a gradient
  3. Add text overlay parameters to the URL
  4. Specify font size, color, and position within the URL string
  5. Programmatically update the text parameter to reflect different city names

Options

  • Add colored blocks instead of gradients
  • Overlay images instead of text
  • Apply the same transformations to video files

Tips

  • Use programmatically generated images for websites, apps, emails, or push notifications
  • Apply these transformations to videos to avoid setting up a separate video processing pipeline
