JpgXr compression in CZI

[darwinjob]

According to the CZI reader source code only JPEG(1) and LZW(2) compressions are supported:

Code: Select all

      switch (directoryEntry.compression) {
        case JPEG:
          data = new JPEGCodec().decompress(data, options);
          break;
        case LZW:
          data = new LZWCodec().decompress(data, options);
          break;
      }

Are there any plans to read JpgXr (4)?

Best regards
DD

Yes, support for JPEG XR compression is planned. Please see this ticket on our issue tracking system:

I am just following up on this JPGXR issue. Initially it would be good to find out how many other users require the availability of this option for import into OMERO?

We are currently looking at a large image database that can only be saved in the JPGXR 85% format and have not seen that there is currently a (non-commercial) solution available for this image format. I understand that this lossy format is not suitable for all research users but it would be good to identify others in this community who have a similar need for this solution.
