lctio-retiff

name	lctio-retiff
description	Use when modifying or debugging lctio.retiff, TIFF rewrite behavior, or the retiff CLI.

LCTIO Retiff

Use this skill when a task touches src/lctio/retiff/ or the retiff command.

Current Behavior

• retiff reads a TIFF file and rewrites it with simpler storage and minimal metadata.
• The tool preserves image shape, sample values, and photometric interpretation.
• The library entry point is lctio.retiff.rewrite().
• The CLI entry point is retiff, defined in pyproject.toml.

Important Constraints

• Only single-page TIFF files are supported. Multi-page input should raise an error.
• The project intentionally relies on PIL for broad TIFF read compatibility and tifffile for writing.
• The repository does not depend on imagecodecs.

CLI Examples

• retiff input.tif
• retiff input.tif -o output_dir/
• retiff *.tif -o simplified/
• retiff input.tif -v
