$imageformat
Defines which image format to use for retrieving images (e.g., $imageformat=png)
Description
Define which format to use to display images. By default, the best format for the image will be chosen. You can, however, select one of the following formats:
| Type | Description |
|---|---|
| GIF | GIF format |
| PNG | PNG format |
| JPEG | JPEG format |
| TIFF | TIFF format |
| best | Best format based on the image |
Once you have defined the format, you must pass the image attribute to $expand to load the photo completely.
If there is no image to be loaded or the format doesn't allow the image to be loaded, the response will be empty.
Example
The following example defines the image format to JPEG regardless of the actual type of the photo and passes the actual version number sent by the server:
GET /rest/Employee(1)/photo?$imageformat=jpeg&$version=3&$expand=photo
