If you want to investigate improving downsampling quality, in the mentioned BrandedPreviewJPEGFilter, this is where it takes place: https://github.com/DSpace/DSpace/blob/master/dspace-api/src/main/java/org/dspace/app/mediafilter/BrandedPreviewJPEGFilter.java#L137 For starters, here's some pointers on how to change the sampling method: http://stackoverflow.com/questions/4216123/how-to-scale-a-bufferedimage If you find out that downsampling quality indeed can be improved, be sure to share it back with us! One thing I'm not sure about is which filter is used when (I'd guess JPEGFilter, but BrandedPreviewJPEGFilter uses the webui.preview.maxwidth/maxheight properties), so you may want to figure that out, too. > Anyway at this point we may see if by making the image larger and use CSS to > make it show small in some pages (results list) and bigger in others (full > view of item). So you need both better quality and two thumbnail sizes?
