Hello Team,
I am try to use Clipper function in Python API for Raster.
When i run my Workspace a crash is happen:
Attached my Workspace.
Thanks in Advance,

Hi @danilo_inovacao, the FME Objects API doesn't have any capability to read and create an FMERaster object from a raster file path, except a case where you read a raster feature from a file using an FMEUniversalReader object.
If the input feature has a raster geometry, this script works to clip the raster held by the input feature and update (overwrite) the geometry of the feature with the clipped raster.
# PythonCaller Script Example: Clip a Raster
# Assuming that the input feature always has a raster geometry.
import fmeobjects
class FMERasterTools(object):
def input(self, feature):
# Clipper's extents.
# Modify these values appropriately according to the requirement.
xMin, yMin = -97.6864, 30.3571
xMax, yMax = -97.6802, 30.3509
# Retrieve the geometry (FMERaster object) from the input feature.
raster = feature.getGeometry()
# Create an FMERasterTools object.
rasterTools = fmeobjects.FMERasterTools()
# Clip the original raster by the specified extents.
# The FMERasterTools.clip() method returns a clipped raster.
newRaster = rasterTools.clip(xMin, yMin, xMax, yMax, raster)
# Set the clipped raster to the feature.
feature.setGeometry(newRaster)
# Output the feature containing the clipped raster.
self.pyoutput(feature)

Thans your explatnation and comments inside the code.
The explanation was very powerful with this my Doubt.
