just started using fme to do my raster processing and am thrilled with the quality and speed of the output. That said I can't seem to figure out a couple of things. Perhaps you all might be able to assist.
1) When I mosaic images and push into jp2, the empty areas end up black, is there a way to make the empty areas transparent?
2) Is there a way to produce prj files for my output images based on the output projection?
1) Those areas should be tagged with a NODATA value. If they aren't already then you should be able to set that with a RasterBandNodataSetter transformer. Then it's up to your viewing software to recognize them as NODATA and display them transparently.
2) You can create a TAB file for jp2, but not a prj. So, what you can do is use the CoordinateSystemExtractor to extract the coordinate system, then use that in a CoordinateSystemDescriptionConverter transformer to convert it to Esri WKT. Then I think you just need to write it out to a prj file (say with the AttributeFileWriter)
Hope this helps

I've had the same problem with any lossy compression (ECW, SID, JPG).
