Image::ExifTool::Import - Import CSV and JSON database files
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 flag to set '-' values to undef in the database. (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.
