Image Sequencer is an online tool for image processing -- based on the idea of a storyboard. Each modification makes a new copy of the image, resulting in a series of images showing each step.

See the diagram above!


Image Sequencer is different from other image processing systems in that it's non-destructive: instead of modifying the original image, it creates a new image at each step in a sequence. This is because it:

  • produces a legible trail of operations, to "show your work" for evidential, educational, or reproducibility reasons
  • makes the creation of new tools or "modules" simpler -- each must accept an input image, and produce an output image
  • allows many images to be run through the same sequence of steps - batch processing
  • works identically in the browser, on Node.js, and on the command line
