@darkma773r Thanks a lot for creating that pull request. Really clever the intermediate `GenericImageParser`. I liked it and might use it later! :+1: A few questions/notes, feel free to point if any of what I say is off the mark. 1. If the `JpegImageParser` requires a parameter different than the `TiffImageParser`, I assume we would have to create a new `JpegImagingParameter`. In that case, wouldn't we have to keep the old constructor for backward compatibility until a new major release? 2. I think it would be best if cases like this were not allowed `PcxImagingParameters parser = new PcxImagingParameters(new TiffImagingParameters()); // no error in compile or runtime` 3. I think you removed the option to allow `null` parameters in the `Imaging#writeImage` method (and other methods). I thought about doing that too, that would remove one generic suppress I think, but there are unit tests and examples. The API has allowed it since Sanselan, so not too sure about enforcing parameters to be non-null now. 4. I liked the error in this one `new PngImageParser().writeImage(null, null, new TiffImagingParameters());`, which gives `java.lang.IllegalArgumentException: Invalid imaging parameters: expected type...` Your design really solves the generics problems, so I will take another look later and see if I find a middle way. See what you think about the `null` parameters, and allowing the empty parameters types for `Jpeg` and other parsers, or about the other notes @darkma773r :+1: Thanks heaps! ```java Imaging.writeImage((BufferedImage) null, (OutputStream) null, ImageFormats.GIF, new TiffImagingParameters()); // java.lang.IllegalArgumentException: Invalid imaging parameters: expected type org.apache.commons.imaging.common.XmpImagingParameters or a super class but was org.apache.commons.imaging.formats.tiff.TiffImagingParameters :+1: ``` -- This is an automated message from the Apache Git Service.
