Hello Everyone, I am facing another issue. I am fetching some images from source and store them to destination and just before destination processor I have ResizeImage Processor.
Now my images can be JPEG or PNG. Processor documentation mentioned that it can handle both but it is failing for PNG files with the following error: ResizeImage[id=2b2bf869-0dcb-351d-857b-bbeef6f27fcf] ResizeImage[id=2b2bf869-0dcb-351d-857b-bbeef6f27fcf] failed to process due to java.lang.IllegalArgumentException: Unknown image type 0; rolling back session: Unknown image type 0 I did some digging and it seems like the issue is with ImageIO library being used for resizing. https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-media-bundle/nifi-media-processors/src/main/java/org/apache/nifi/processors/image/ResizeImage.java#L177 As per this thread "image.getType()" method is the one which creates problem. https://www.thecodingforums.com/threads/imageio-have-problem-of-reading-png.141174/ https://stackoverflow.com/questions/5836128/how-do-i-make-javas-imagebuffer-to-read-a-png-file-correctly So seems like for PNG files image.getType returns 0 but it is expecting 5. *Is there any workaround for this without changing the code?* If there is none, I can fix the code and use (can also submit a pull request with the fix but I am not sure how to do that.) Kind Regards, Raman
