Many times, I run into the following situation...
I made an analisys, resulting in a raster-object... (DEM or whatever), and I want to nicely present this black-grey, one-band result.
I can of course recalculate all cells to integers, use a RasterPalletteGenerator or calculate some RGB-values for each cell.. but that is cumbersome. To my experience in general raster transformers are less intuitive than vector ones...
So I revert to QGIS giving me a nice drop-down menu with pallette options, color-ramps, breakpoints, classification and whatever to make my raster visually appealing and informative.
Having something similar in FME would not only make my life easyer, but allow me to automate stuff on Server, and stream results as a nicely styled raster.
Kind regards,
Martin
