How to remove black areas from mosaicked ECW image?

I have used RasterMosaicker to mosaic 4 ECW images into a single ECW image. Prior to mosaicking none of the images had black areas around the edges. After mosaicking my output shows two locations that are black on the edge of the image. I checked and these black areas have data, various values of 1,0,1; 0, 1, 0; 1, 2, 1; and several other values. Any suggestions on how to remove the black areas? I have tried Clipper and it does not clip the black areas, they remain in the output.

Separate address values in a single field on left and right side of "/" separator to a new field

I have a table of addresses with these values in a single field, example: Main St/Carter Ave. I want to put Main St in a new field named StreetName, and Carter Ave in a new field named IntStreetName. I know there must be a method for parsing the values to the left and right of the "/" separator. How can I do this in FME? I know how to do this in python using split. I am new to FME.

How can I fan out to individual features in a GDB based on the "LAYER" attribute found in my data?

I realize the fanout option is probably the best option. I have not used FME in quite a while and am looking for someone to spoon feed this to me. I need to read in a single GDB and export to another GDB based on the "LAYER" field.

Copy Excel Data and Apply Transformation

We currently have an Excel macro to copy cell data from an Excel source sheet and paste to another destination sheet. Once pasted, we will position those data in particular columns and apply some lookups.What would be the best approach to mimic such process in FME? Is it feasible to execute all those detailed steps by using FME transformer(s)?

System Caller process and release

I have a workbench that has around 7000 features and I want to run a system caller on each to produce an image (png) output, convert that image to a blob, store the blob in the database and delete the file. At present the System Caller is processing all features before it moves on. Is it possible to have the system caller run for an individual feature and continue on with the process?

Snapping points or lines to a surface?

I am attempting to snap points or lines to multi-face surface features. I realize the 3D AnchoredSnapper does not snap to surfaces. Any thoughts on how to perform this. I would be ok with converting the surface features into lines since that is my ultimate goal. Any thoughts on techniques or transformers?

How do you drop FME features in the PythonCaller?

I am trying to drop features in the PythonCaller (see below my code). I manage to delete attributes and geometry in the last else statment, but for some reason the feature itself is not deleted. The number of features in the input and output is namely the same, while the geometry is gone (Look at the image below) . I just find it interesting to see that the features without geometry are still kept. Does anyone know how I can drop the features in the Pythoncaller in the else statement when I am removing the redundant geometry?import fmeobjects def processFeature(feature): lstAttributes = feature.getAllAttributeNames() testList:=['B-OI-KL_ET_MS_KABELBED-G'] for lvl in lstAttributes: if lvl == 'igds_level_name': levelName = feature.getAttribute(lvl) if levelName in testList: print(levelName) #print(levelName) for attr in lstAttributes: if len(at
