I'm new to FME, and I need to transform a Packbit compressed geotiff file to a LZW compressed geotiff file. I'm using a geotiff reader and a geotiff writer, the later configured to use LZW compression. The output file is still in packbits
Solved
Convert Packbits geotiff to lzw

Hi @juanpablomenich, I was able to reproduce the same situation: Read a raster feature from a geotiff file compressed by pack-bits method with GEOTIFF reader, write the raster with GEOTIFF writer having "lzw" set as the Compression Method parameter, but the resulting geotiff file is still compressed by pack-bits method.
I guess that a format attribute called "geotiff_compression_method" defined by the reader conflicts with the Compression Method parameter setting for the writer Try once exposing the "geotiff_compression_method" attribute and removing it before writing.
