> use better image downscaling method in filter-media
> ---------------------------------------------------

> Project: DSpace
> Issue Type: Improvement
> Components: DSpace API
> Reporter: Ivan Masár
> Assignee: Ivan Masár
> Fix For: 4.0
>
> Attachments: BrandedPreviewJPEGFilter.java, JPEGFilter.java
>
>
> Users are unsatisfied with current quality of images downscaled by
> filter-media. This leads to using workarounds like creating higher resolution
> thumbnails and letting the user's browser downscale the image, which is
> bandwidth-inefficient. The right solution would be to find a better
> downscaling method.
> One proposed option would be to use the Apache-licensed, Maven-dwelling,
> GitHub-using pure-Java Imgscalr library:
> http://www.thebuzzmedia.com/software/imgscalr-java-image-scaling-library/
> The current code that needs to be changed is here:
> https://github.com/DSpace/DSpace/blob/master/dspace-api/src/main/java/org/dspace/app/mediafilter/JPEGFilter.java#L136
> and in BrandedPreviewJPEGFilter.java
