Compose Images
Description
Use this Step to arrange multiple images at specified positions and compose them into a single image.
Usage Scenario
This Step is suitable for scenarios where multiple images are stitched together into one result image at a set position. For example, images from different regions can be grouped into the same image, or multiple images can be arranged by a specified displacement and output together.
You can obtain input images from Steps that perform functions such as image capturing, image reading, cropping, or scaling, and output the stitching results to Steps that perform functions such as visualization, image saving, or detection and analysis.

The process of configuring this Step is shown below:
-
Set the number of images to be stitched in the Parameters section.
-
Configure the input. Connect the Step ports in the graphical programming workspace or select the input under Input in the parameter configuration panel.
-
Set the image position.
-
Run the Step, and view output.
