Here’s an example of how the activity is used in the workflow –

In the following example, I am going to use a sample image to enhance the quality.

Example

1. Create a new solution or open an existing workflow.
2. Drag and drop the image enhancement activity into the workflow and set it as start node.
3. Here I am navigating to the “ImageInput” in the properties section, to provide the path of the image.
4. Then, moving to the “Sharpening” in the properties section to enhance the image quality.
a. Here I am specifying the value as “True”.
5. Now, moving to the “ImageOutput” property to provide the path of the image to store the output.
6. Next, moving to the “On-screen image” property specifying the value as true.
7. Now, Execute the workflow.
