I would like to to use the DirectoryAndFilePath Reader to assemble a list of file paths, and then feed tha to a JPEG reader as the list it should read.
I have also looked at the FeatureReader, to see if it could be used under program control.
But I am drawing a blank. Any hints?
you could either split it into 2 workspaces and use the WorkspaceRunner to pass the list of JPEG files from the DirectoryAndFilePath reader, or you could use a Scripten Python parameter with something like this:
import glob files = glob.glob(r'C:\\my_jpegs_are_here\\*.jpg') name_list = '"' + " ".join(o'"' + x + '"' for x in files]) + '"' return name_list
Link the scripted parameter to the JPEG readers "Source JPEG File(s):" parameter.

For raster features you can better use the RasterReader. Works like a charm.
