Version 1.0


Do you want to automatically create thumbnails of LocalFocus charts and maps? This is the place to start!

The LocalFocus Thumbnail API uses HTTP requests. The results are PNG images, with optional retina support. To use this API, you need an API key. Please request one here. We encourage you to cache generated thumbnails, to reduce API calls.
