Trims edges from an image. Enter number of pixel rows/columns to trim from image. You can use the Preview function to tweak the trim level setting to your needs. This is useful for cutting off rough or skewed edges or otherwise if you need a rectangular image.
One limitation of this Model is that the rows and columns aren't physically trimmed from the file - the output image still has the same number of rows and columns as the input file, but the specified number of edge rows and columns have been set to have a pixel value of 0 in the output. In ERDAS IMAGINE 2016 we will be able to use the Define Processing Area operator to physically trim edge rows/columns (and a new Article will be posted with that Model).
Raster Input File: enter the filename of raster to trim
