Image pipeline

Cleans and reorients one of this project's pyramid stills in a single pass.

When to use this

The user asks to remove the star, transpose the image, reorient it, or "run the pipeline" on a pyramid still. It handles the pair together; for one half only, call the individual script.

How to run it

scripts/pipeline.sh <input_image> <output_image>

Stage 1 fills the star and its ground shadow with the background colour #EFE9DF. Stage 2 transposes what is left, so a 502x460 input leaves as 460x502. The intermediate goes to a temp directory and is removed on exit.

Rules

• Run the script. Do not rewrite what it does as a fresh `convert` call.

The polygon coordinates in scripts/remove_star.sh were traced against one specific image; a regenerated command will not match them.

• `-transpose`, never `-rotate 90`. Both turn 502x460 into 460x502, so the

obvious check passes on either, and they differ in 97024 pixels. The pipeline uses -transpose.

• Verify before reporting success. Run scripts/verify.sh <input> <output>.

It checks the shape, that transposing back reproduces stage 1, and that the result is not what -rotate 90 would have made. Report what it prints.

• Only ImageMagick and bash. No Python.
• If ImageMagick is missing, say so and stop; do not substitute another tool.
