But OFBiz doesn't implement JAI ? So I haven't used his example Now into the file ScaleImage.java I don't use anymore interpolation code (from the line 165 "Double scaleFactorDb" to the line 193 "return result;}" if it's better, I can delete the interpolation code into the patch > Image scaling quality > --------------------- > > Key: OFBIZ-2552 > URL: https://issues.apache.org/jira/browse/OFBIZ-2552 > Project: OFBiz > Issue Type: Improvement > Components: framework, product > Affects Versions: SVN trunk > Environment: linux Debian, trunk revision 779985 > Reporter: Eric DE MAULDE > Priority: Minor > Fix For: SVN trunk > > Attachments: scaleImage.patch > > > We can improve image scaling quality with an other JAVA algorithm > Comparison of different JAVA image algorithms > http://www.hanhuy.com/pfn/java-image-thumbnail-comparison > the algorithm with the best quality is AWT SCALE_SMOOTH -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. |
