Image::ExifTool::Import - Import CSV and JSON database files
use Image::ExifTool::Import qw(ReadCSV ReadJSON); $err = ReadCSV($csvFile, \%database); $err = ReadJSON($jsonfile, \%database);
Exports nothing by default, but ReadCSV and ReadJSON may be exported.
Read CSV or JSON file into a database hash.
0) CSV file name or file reference.
1) Hash reference for database object.
2) Optional string used to represent an undefined (missing) tag value. (Used for deleting tags.)
3) [ReadJSON only] Optional character set for converting Unicode escape sequences in strings. Defaults to "UTF8". See the ExifTool Charset option for a list of valid settings.
These functions return an error string, or undef on success and populate the database hash with entries from the CSV or JSON file. Entries are keyed based on the SourceFile column of the CSV or JSON information, and are stored as hash lookups of tag name/value for each SourceFile.
