Ciao Jacob,
basically, Imageio-ext is a java project extending Java Sun's ImageI/O
framework capabilities. It is composed of several modules adding
specific features to ImageI/O like, as an instance, supporting more
raster data access capabilities and providing multithreading imageread
operation. It is an integration framework which aims to extend the
basic imageio capabilities for java.
The main module of the project is gdalframework, a framework
leveraging on GDAL to get access to a wide range of raster data
formats, mainly used in the geospatial world.
ImageIO-ext contains an experimental Jpeg plugin leveraging on
Jmagick, which was used to demontrate that imageio-ext could help with
integrating/exposing jmaigck using standard imageio capabilities.
Conclusion is, I think it would great integrating the JMagick
capabilities into imageio-ext in order to access formats like jpeg and
png in a more performant way. I am not sure it would make sense to put
imageio-ext inside jmagick :-).
My suggestion would be creating a module specific for JMAGICK which
would handle most part of the mechanics plus some plugins for the
formats we want to support and the support for metadata we want to
implement (not much at the beginning I guess :-)).
What do you think?
Simone.
