@FM list of all metadata tags
Remarks
The GetMetaData method gets all metadata tags associated with the given model. In most images, metadata is grouped or categorized into models. Within a model is a series of tags. Each tag has a key, a value, and a description. There are currently 11 recognized models:
| Name |

| Comments |
| ExifMain |
| ExifAdvanced |
| ExifGPS |
| ExifMaker |
| ExifInterop |
| IPTC |
| XMP |
| GeoTiff |
| Animation |
This method will return an @FM delimited list of tags. Each tag has the following @VM delimited structure:
| Pos | Name | Type | Description |
|---|---|---|---|
| <1, 1> | Key | Text | The tag's key ID |
| <1, 2> | Value | Text | The tag's value |
| <1, 3> | Description | Text | The tag's description |
To get a list of models stored in the image, use the GetMetaDataModels method. To get a single tag, use the GetMetaDataTag method.
Example
// Get the meta data for the first model Models = Send_Message(@Window:".OLE_PICTURE", "OLE.GetMetaDataModels") Tags = Send_Message(@Window:".OLE_PICTURE", "OLE.GetMetaData", Models<1>) // Explicitely get all tags from the Comments model Tags = Send_Message(@Window:".OLE_PICTURE", "OLE.GetMetaData", "Comments")
