MIME type improvements
^^^^^^^^^^^^^^^^^^^^^^
Previously, all JPEG2000 images had the MIME type "image/jpx". This has now been
corrected. After the file format drivers have been loaded, ``Image.MIME["JPEG2000"]``
will return "image/jp2". ``ImageFile.get_format_mimetype`` will return "image/jpx" if
a JPX profile is present, or "image/jp2" otherwise.
Previously, all SGI images had the MIME type "image/rgb". This has now been
corrected. After the file format drivers have been loaded, ``Image.MIME["SGI"]``
will return "image/sgi". ``ImageFile.get_format_mimetype`` will return "image/rgb" if
RGB image data is present, or "image/sgi" otherwise.
MIME types have been added to the PPM format. After the file format drivers have been
loaded, ``Image.MIME["PPM"]`` will now return the generic "image/x-portable-anymap".
``ImageFile.get_format_mimetype`` will return a MIME type specific to the color type.
The TGA, PCX and ICO formats also now have MIME types: "image/x-tga", "image/x-pcx" and
"image/x-icon" respectively.
