Hi, I am trying to execute command as below which throw me the errors.

     String [] cmdPng = {"D:\\pngquant\\pngquant.exe", "--quality=90-95", localDir+assetDetails.getName(), "--ext", ".png", "--force"};
            LOGGER.info("Command is {}",Arrays.toString(cmd));

Logger output -- Command is [D:\pngquant\pngquant.exe, --quality=90-95, C:\Users\vdhim6\Desktop\imgcompression\test.png, --ext, .png, --force]

Error is --

error: Read error (libpng failed)
 error: cannot decode image C:\Users\vdhim6\Desktop\imgcompression\test.png

D:\pngquant>pngquant -h

The image is corrupted.

This works fine if I do via command line. Hence I don't think image is corrupt. PFA.

Thanks,

Oh, that's interesting.
