Get Image Metadata Activity

Description

The Get Image Metadata activity gets the metadata attached to an image if it exists.

Usage

A workflow could use the File Picker form element in a Display Form activity to get an image from the end user. The end user's image may have location data attached to it. The workflow could use the Get Image Metadata activity to create a point on a map at the location that it gets from the metadata.

Inputs

Required Type: Number[] The byte content of the image. Bytes are the raw binary values that represent content. A byte array is represented by a list of numbers between 0 and 255. Invalid byte content will cause an error. One way byte content can be retrieved is by using the Read File Bytes activity.
