Sepia Watermark + Frame Example

This example applies a sepia tone to the uploaded image, overlays a watermark in the corner, and adds a white frame. It demonstrates how to chain multiple processors using shared memory paths.

Demonstrates

• Chaining multiple processors using mem/ paths
• Using the color_transform processor with an effect
• Compositing a watermark with anchors and opacity
• Referencing an image from the account store (account/watermark.png)
• Drawing a border using the frame processor with composite: True
• Final output written to output/output.png

Definition

- processor:
    processor: "color_transform"
    inputs:
      source: "input/input.png" # upload
    params:
      effect: "sepia"
      intensity: "1.0"
    outputs:
      target: "mem/work.png" # save to memory

- processor:
    processor: "composite"
    inputs:
      background: "mem/work.png" # load from previous
      overlay: "account/watermark.png"
    params:
      background_anchor: "rel(1.0,1.0)" # bottom right
      overlay_anchor: "rel(1.0,1.0)" # bottom right
      width: 50 # size in pixels
      opacity: 0.5 # 50% transparency
    outputs:
      target: "mem/work.png" # update memory

- processor:
    processor: "frame"
    inputs:
      source: "mem/work.png" # load from previous
    params:
      composite: "True"
      size: 10
      color: "#FFFFFF"
    outputs:
      target: "output/output.png" # final output.
