Reading Metadata
Release 1.02 - ...
Use the module se:imageproperties to obtain metadata information from images. The module returns a data table containing the image properties of one or more images. Each table row contains the details of a single image. When the parameter includemetadata is enabled, the cell of the metadata column is filled with a datatable containing the complete set of metadata that is found. Nested datatables (a datatable in a datatable) are used to store the metadata information.
ImageProperties Result
The image properties module datatable result contains the following columns:
| Name | Type | Description |
|---|---|---|
| FileName | String | The name of the file. |
| FileType | String | The type of the image. The complete list of supported image types is defined in the Smartsite.ImageProcessor.config. |
| Folder | String | The parent folder of the image (if applicable) |
| FileSize | Integer | The actual file size in bytes. |
| FileSizeKb | String | A formatted file size in kbytes. |
| Width | Integer | The image width in pixels. |
| Height | Integer | The image height in pixels. |
| ColorDepth | Integer | The number of colors per pixel. |
| FrameCount | Integer | The number of image frames found. More than 1 when the image contains a sequence of images, as is the case with animated GIF images. |
| ResolutionUnit | String | The image resolution unit. |
| ResolutionX | Float | The horizontal resolution. |
| ResolutionY | Float | The vertical resolution. |
| Location | String | The absolute location of the image |
| Metadata | DataTable | The complete set of metadata found in the source image. Not set if parameter includemetadata is false. |
Metadata DataTable
Once metadata is requested using the includemetadata parameter and metadata is found in the source image, the metadata datatable is filled and contains the following columns:
| Name | Type | Description |
|---|---|---|
| Id | String | The unique identifier of the metadata element as defined in the metadata format. |
| Name | String | The mapped name of the metadata element. The metadata parser provides a mapping of metadata identifiers to human readable names. A full mapping for Exif and IPTC metadata has been implemented. |
| Value | Any | The actual value of the metadata element. |
| Type | Enum (DataType) | The datatype of the metadata element value. |
| Source | String | The name of the source metadata format. Either ComText, Exif, IPTC or XMP |
| Category | String | The category of the metadata element (if supported by the metadata format). |
| Description | String | A description of the metadata element (if supported by the metadata format). |
