#1084 Jpeg-XR support
Can you implement the Jpeg_XR support? https://en.wikipedia.org/wiki/JPEG_XR
You mean for importing or exporting? Do you know any library for Java?
To recognize and display. The program is exporting files, but don't know what is.
So you want to import Jpeg XR images to DefineImage tags, or what do you mean by recognise? I'm sorry, but without a 3rd party library it is not possible, we won't implement an image processing library. (Or you want to do it, JPEXS?)
