Media_GetMetaData (image)

Media_GetMetadata ( container )

This variant of Media_GetMetadata is intended for images. For the sound variant of the function please refer here.

This function returns any metadata text associated with the specified image.

Parameter Description
container The location of the image.
The container parameter can be:

  • a container field
  • file path
  • text field with a file path

Most image files also have a small block of metadata text associated with them that gives basic information like image creation date and the software used to create it.

A common response might look like this:

IPTC
©swr: Adobe Photoshop 7.0
©day: 2003-11-16 13:07:07

Creation software is specified by “©swr” and creation date by “©day”.

You can use the Media_ExtractInfo function to isolate specific elements of the metadata. See the examples below.

Examples

To get the metadata for an image in a field named Picture and put it into a field named Meta:

Set Field [ MyTable::Meta ;
Media_GetMetadata ( MyTable::Picture ) ]

To use Media_ExtractInfo in order to isolate the creation software and place the result in a field named Creator:

Set Field [ MyTable::Creator ;
Media_ExtractInfo (
Media_GetMetadata(MyTable::Picture);
“IPTC/©swr” ) ]
