In the past I've received 2 file MRSID files, 1 RGB and 1 Color Infrared, this time got a 1 MRSID file with all 4 Bands. I can RasterSelector then RasterBandRemover and get the RGB, this takes a little longer as I need to pass it thru transformer.
Question
Can I read a MRSID and only select the RGB Bands and not read the Color Infrared (Apha) as if I don't need it why read it (would this speed up the Workspace processing)?
I would suggest instead that you use the RasterSelector for bands 0;1;2 and a RasterBandKeeper. That way the workspace won't fail if you send it a 3 band image, or a mix of 3 and 4 band images.
As long as feature caching is not enabled, this should have minimal impact on your workspace performance.

Thank-you, instantly runs faster
Am I confused or is this thread saying that FME can remove the 4th band and make the .sid file into a 3-band one? I though .sid was a read only format in FME? I run into this problem with having 4 or 5 band sid files but I need them to only be 3-band files so AutoCAD can read them.
