Image Formats
=============

Preferred Extensions and Mime Types
-----------------------------------

Images can generally be read regardless of their name.  By default, when opening an image with ``large_image.open()``, each tile source reader is tried in turn until one source can open the file.  Each source lists preferred file extensions and mime types with a priority level.  If the file ends with one of these extensions or had one of these mimetypes, the order that the source readers are tried is adjusted based on the listed priority.

The file extensions and mime types that are listed by the core sources that can affect source processing order are listed below.  See ``large_image.listSources()`` for details about priority of the different source and the ``large_image.constants.SourcePriority`` for the priority meaning.
