I'm a total FME novice trying to convert an ecw (Generated from a tif) to a jpg, but it keeps failing because the jpg writer cannot support more than 3 bands....
What are these bands and how do i get around this problem? I just need a straight forward jpg.. no coordinates.
Thanks in advance for your help..
If you need to only keep specific three bands (or remove other than them), you can use the RasterBandKeeper or the RasterBandRemover. See the help documentation on them.
Hi,
You need to use a RasterSelector to select the band you want to remove with the RasterBandRemover

Hi @lau, thanks for sharing your answer and taking the time to mock up a workspace! Unfortunately, it looks like the Forums had a hiccup during the upload and I can't seem to access the file. Would you be able to upload your workspace file again?
Hi @paulgaughanv,
To add onto @lau and @takashi's excellent answers, I just wanted to link a few resources that they have already mentioned and any examples I can think of for any other novice users stumbling upon this question in the future:
JPEG writer documentation - includes an explanation of parameters and supported features
RasterSelector and the RasterBandRemover transformer
This example converts GeoTIFF to ECW but it provides a good working example of the RasterSelector and RasterBandRemover
It might be good to inspect your source data (either in the Data Inspector or the Visual Preview) and check that you have 3 bands, for example: Band 0 (RED8), Band 1 (GREEN8), Band 2 (BLUE8). And if you have more than that, then consider using either the RasterBandRemover or RasterBandKeeper as takashi has suggested. I believe the RasterBandKeeper might be the easiest method for you to just select Red, Green, and Blue.
Let us know how that works for you (:
