DEBUGGING

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 a GIF image.
known_fields
Returns the fields which this writer knows about. This writer has no limitations.
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();delete_field_from_file
Completely remove the given field. This does no checking.
$writer->delete_field_from_file(filename=>$filename,field=>$field);replace_all_meta
Overwrite the existing meta-data with that given.
(This supercedes the parent method because we can do it more efficiently this way)
$writer->replace_all_meta(filename=>$filename,meta=>\%meta);replace_one_field
Overwrite the given field. This does no checking.
$writer->replace_one_field(filename=>$filename,field=>$field,value=>$value);Helper Functions
Private interface.
_load_meta
Quick non-checking loading of the meta-data. Does not standardize any fields.
my $meta = $self->_load_meta($filename);_write_meta
Write the meta-data as YAML data in the Comment field. This overwrites whatever is there, it does not check. This saves multi-value comma-separated fields as arrays.
$self->_write_meta(meta=>\%meta,filename=>$filename);_get_the_real_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);BUGS
