Hi @marcelosouza25,

Do you want to get the values RGB from a geotiff file? If yes you can see this Question Extract RGB value from Raster

If not, could you share us your Workspace template ( .FMWT )?

Thanks,

Danilo

Hi @marceloraizen25, I found your sample raster data has four bands. What is the rule to convert the values of four bands to R, G, B values?

If you know the rule (mathematical expressions or detailed specifications on the source raster, etc.), it's possible to convert the source raster to an RGB color image with some transformers. Otherwise, it would be hard to make desired color image.
