Implement Bicubic interpolation for resizing on thumbnail generation
--------------------------------------------------------------------
Key: MGNLDAM-2
URL: http://jira.magnolia-cms.com/browse/MGNLDAM-2
Project: Magnolia DAM Module
Issue Type: Improvement
Affects Versions: 1.0 Alpha S8
Reporter: Christopher Zimmermann
Assignee: Christopher Zimmermann
Bilinear interpolation is the default in BasicResizer.java.
But it looks bad and Bicubic looks good. But bicubic is much slower. 2 to 4
times slower in my tests.
In experiments, I was able to change a specific resize operation
"BoundedResize" to be able to accept an "interpolation" node on its
configuration.
But I want to see if its possible in a more generic way to set "interpolation"
as a parameter, so it doesnt have to be built in specifiically for every
operation.
BoundedResize extends AbstractCropAndResize.java which has a BasicResizer as a
member.
Is there not a way to configure the BasicResizer itself via configuration node?
Perhaps. I will ask Gregory.
For best quality bicubic would be used everywhere - but bilinear resizing is
passable for bigger images. It looks bad on small images.
