I have a 4 band TIFF image (RGBa), where the "a" band is the near infrared band.  I need to create an RGB image from this where the "a" band is mapped to the Red channel, the Red band is mapped to the Green channel, and the Green band is mapped to the Blue channel.  This would create a "false colour" RGB image that enhances the vegetation.  I'm pretty sure this can be done but I don't have much experience with Rasters and FME.  Any help would be appreciated on which transformers to use.

 

thanks
