Create Paraxial Rectangle
Use this tool to create one or more regions of interest (ROIs) in form of a paraxial rectangle. A default paraxial rectangle is automatically generated when the tool is inserted. You may adapt the size and position of the paraxial rectangle or add further ones using the ROI button .
Parameters
Basic Parameters
Image:
This parameter represents the input image.
X Center:
This parameter defines the position of the paraxial rectangle in X direction. The "X Center" is measured at the center point of the paraxial rectangle. It is defined in pixels and set to 200 px by default. You can change the position interactively in the image by dragging the handle in the center of the paraxial rectangle. The value of the "X Center" is automatically adjusted. Alternatively you can change the position at the corresponding connector.
Y Center:
This parameter defines the position of the paraxial rectangle in Y direction. The "Y Center" is measured at the center point of the paraxial rectangle. It is defined in pixels and set to 200 px by default. You can change the position interactively in the image by dragging the handle in the center of the paraxial rectangle. The value of the "Y Center" is automatically adjusted. Alternatively you can change the position at the corresponding connector.
Width:
This parameter defines the width of the paraxial rectangle. It is defined in pixels and set to 60 px by default. You can change the "Width" interactively in the image by dragging the borders of the paraxial rectangle. The value of the "Width" is automatically adjusted. Alternatively you can change the "Width" at the corresponding connector.
Height:
This parameter defines the height of the paraxial rectangle. It is defined in pixels and set to 100 px by default. You can change the "Height" interactively in the image by dragging the borders of the paraxial rectangle. The value of the "Height" is automatically adjusted. Alternatively you can change the "Height" at the corresponding connector.
Additional Parameters
ROI:
This parameter defines the region of interest (ROI) for the processing. A default paraxial rectangle is automatically generated when the tool is inserted. You can adjust the default rectangle to your preferences or add further paraxial rectangular ROIs using the ROI button . If you want to use an ROI of a previous tool, you have to connect the parameter to the respective ROI result of a previous tool to make sure that an ROI is transmitted to this tool.
Results
Basic Results
Rectangle:
This result returns the created paraxial rectangle ROIs.
Tool State:
"Tool State" returns information about the state of the tool and thus can be used for error handling. Please see the topic Tool State Result for more information about the different tool state results.
Additional Results
Processing Time:
This result returns the duration of the most recent execution of the tool in milliseconds. The result is provided as additional result. Therefore, it is hidden by default but it can be displayed via the button beside the tool results. For more information see the section Processing Time in the tool reference overview.
