METHODS
priority
The priority of this writer. Writers with higher priority get tried first.
allowed_file
If this writer can be used for the given file, then this returns true. File must be one of: PDF or an image which is not a GIF. (GIF files need to be treated separately) (ExifTool can't write to EPUB)
known_fields
Returns the fields which this writer knows about.
my $known_fields = $writer->known_fields();
readonly_fields
Returns the fields which this writer knows about, which can't be overwritten, but are allowed to be "wanted" fields. Things like file-size etc.
my $readonly_fields = $writer->readonly_fields();
Helper Functions
Private interface.
replace_one_field
Overwrite the given field. This does no checking.
$writer->replace_one_field(filename=>$filename,field=>$field,value=>$value);
delete_field_from_file
Completely remove the given field. This does no checking.
$writer->delete_field_from_file(filename=>$filename,field=>$field);
_get_the_real_file
If the file is a directory, look for a cover file. If the file is a soft link, look for the file it is pointing to (because ExifTool behaves badly with soft links).
my $real_file = $writer->_get_the_real_file(filename=>$filename);
_read_freeform_data
Read the freeform data as YAML data from the XMP:Description field.
my $ydata = $self->_read_freeform_data(exif=>$exif);
_write_freeform_data
Write the freeform data as YAML data into the Description field This overwrites whatever is there, it does not check.
$self->_write_freeform_data(newdata=>\%newdata,exif=>$exif);
_convert_freeform_data
Convert the freeform data so that it is placed into the Description field rather than the UserComment or ImageDescription field.
$self->_convert_freeform_data(exif=>$exif);
