Custom Image

Overview

The Custom Image node generates a solid-color test image with specified dimensions and color. It's used for flow testing and as a placeholder for image processing nodes.

Use Custom Image when:

• You need a standardized image input for testing flow logic.

Example

Visual "Pass/Fail" Indicator

To verify that an operator can clearly see the status of an inspection from a distance, a flow uses a Custom Image node to generate a solid Red or Green frame that fills the dashboard screen whenever a critical failure or successful pass is detected. To dynamically switch between these colors on a single dashboard widget, a Combine node must be used to manage the different image inputs.

Configuration:

• Width: 640
• Height: 480
• Color: GREEN

Result: This solid one color frame is sent to the dashboard, instantly signaling to the floor staff the current product inspection result.
