SYNOPSIS
use Image::ExifTool::Import qw(ReadCSV ReadJSON);
$err = ReadCSV($csvFile, \%database);
$err = ReadJSON($jsonfile, \%database);
DESCRIPTION
This module contains routines for importing tag information from CSV
(Comma Separated Value) and JSON (JavaScript Object Notation) database
files.
EXPORTS
Exports nothing by default, but ReadCSV and ReadJSON may be exported.
METHODS
ReadCSV / ReadJSON
Read CSV or JSON file into a database hash.
Inputs:
0) CSV file name.
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.
Return Value:
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.
