| Description |
|
Implement multiple image resizing as standard for image re-sizer class. Here are some sample of how the quality varies between using our imaging resize vs what results my laptop produces. Imaging module at 100% quality Just flipping through the dam's tour images with Q=100% you can see the images generated for the "portrait" cut (config:/modules/imaging/config/generators/portrait) really don't turn out so sharp. See https://www.baeldung.com/java-resize-image. Currently we use Graphics2D in our MultiStepResizer. Attached code is very rough does not do the cropping ViImageResizer.java |
