Hello,
I have a large TIFF file made with the following command:
gdal_translate.exe source.ecw d:\gdalcogtif.tif -of COG -co COMPRESS=WEBP -co BIGTIFF=YES -co NUM_THREADS=7
This works fine in QGIS, and I’m able to add the layer to GeoServer. When rendering however, I get these errors in the console:
javax.imageio.IIOException: Unsupported compression type (tag number = 50001)!
at it.geosolutions.imageioimpl.plugins.tiff.TIFFImageReader.read(TIFFImageReader.java:1939)
at com.sun.media.jai.imageioimpl.ImageReadOpImage.computeTile(ImageReadOpImage.java:697)
I’d prefer to keep the file that’s provided, and not adding another layer of transformation. Would it be possible to add WEBP decompression for the Image IO library?
Regards,
Jelmer Baas
Hi Jelmer,
in theory yes, but does not seem trivial.
Searching for Java support for webp returns projects that are discontinued or even removed from repositories (like the Luciad one).
The webp library itself seems to have java bindings, but they are not deployed in the Maven repositories it sees, so one has
to build everything from source.
Assuming one can get a encoder/decoder for webp bound to Java, then changes to these libraries should be made,
creating a new TIFFWebPCompressor/Decompressor, and supporting the same TIFF tags that GDAL is using for it in the TIFFImageReader:
https://github.com/geosolutions-it/imageio-ext/tree/master/plugin/tiff/src/main/java/it/geosolutions/imageioimpl/plugins/tiff
Overall, does not seem trivial, but possibly doable.
Cheers
Andrea

Hi Andrea,
Thanks for the reply. I’m currently still not that well versed in the Java world, so I’m afraid this experiment will have to wait. Who knows, one day…
