Using JAI library? #60

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Is there a way to use the JAI library for scaling images?  It looks like we're 
getting CMMException: Invalid Image Format when trying to read certain images, 
and people recommend using the JAI library.

Thank you for taking time to file this feedback.

Sorry for taking long to get back to you.

I'd rather not add JAI as a dependency to Thumbnailator for the following 
reasons:

  1. Thumbnailator is currently a standalone library with no dependencies.
  2. As Thumbnailator is without dependencies it maintains a fairly small footprint.
  3. Adding JAI as a dependency will complicate deployment of Thumbnailator for non-Maven users.
  4. JAI itself appears to be poorly maintained with no releases in the past 7 years.[1]
  5. Licensing for JAI is incompatible with open source.[2]

Therefore, I will not consider using JAI within Thumbnailator.

That said, if you would like to use Thumbnailator along with JAI for reading 
and writing images, I believe it would be possible by using the `jai-imageio`, 
although it would be beyond the scope of the Thumbnailator project to provide 
support for a 3rd party library.
