mapped

Description:

public signal void mapped (string file_module, bool exclude_unmapped)

`mapped` is emitted after a file module registers a mapping and before other processing takes place.

An application may respond to the signal by registering additional mappings or overriding existing values, for example it might override the TIFF ImageDescription tag to format multiple metadata values into the description.

Parameters:

file_module	The file module name
exclude_unmapped	true if the file module cannot handle unmapped values
