# trollimage — Pytroll imaging library

License: permissive · Maintenance: active · Downloads: 80.6K/mo

## What it is and what it does

Trollimage is an imaging library built for the pytroll ecosystem, a collection of tools for satellite data processing and remote sensing. It sits on top of numpy and pillow, providing specialized image handling for scientific and satellite imagery workflows. The package is part of the pytroll project and is used by packages like SatPy to manage image data in remote sensing pipelines.

The library targets researchers and engineers working with satellite and scientific imagery. It requires Python 3.11 or later and depends on numpy and pillow for its core functionality. The package is actively maintained, with recent commits and a stable release history since 2013.

Use it for:

- Processing and manipulating satellite imagery within SatPy workflows
- Handling multi-band remote sensing data in pytroll-based pipelines
- Image format conversion and standardization for scientific imaging applications
- Integrating numpy arrays and pillow images in satellite data analysis

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Trollimage provides image processing and manipulation capabilities for the pytroll ecosystem, wrapping numpy and pillow to handle satellite and scientific imaging workflows.

Yes, if you are working within the pytroll ecosystem or with satellite/remote sensing imagery. The package is actively maintained, has no known vulnerabilities, carries a permissive license, and integrates well with standard scientific Python tools. Medium install friction is acceptable given the availability of prebuilt wheels for modern Python versions.

## Install

pip install trollimage
uv add trollimage
poetry add trollimage

## Installing trollimage

Before you install: Medium install friction due to compiled dependencies (numpy, pillow), but wheels are available for modern Python versions (3.11+) across common platforms. Repository is active with recent commits.

License in practice: Licensed under Apache-2.0 (permissive), allowing commercial and private use with minimal restrictions—suitable for most projects.

Quickstart:

pip install trollimage
import trollimage
# Use with numpy and pillow for image processing in pytroll workflows

Requires Python 3.11 or later; numpy and pillow must be installed (handled automatically by pip).

Verify before relying:

- Specific image formats supported beyond what pillow provides
- API surface and main classes/functions for typical workflows
- Integration points with SatPy and other pytroll packages
