Arc ROI
The Arc ROI control displays an Arc ROI on the displayed image. The origin is linked from a vision pro-
gram tool output. See “ROI Color Properties” on page 4-34 for more ROI color properties information.
Note: You must have an Image Display control in the Control Panel to add this control.
Property Name What it is
Arc Angle The ROI’s angle (in radians). One radian is equal, in degrees, to 180
divided by pi. One degree is equal, in radians, to pi divided by 180. This
can also be stated as approximately 57.296 degrees per radian or
0.01745 radians per degree.
Arrow Visible If True, the ROI’s arrow is visible.
True Color Click in the field to choose the ROI’s True color.
Draw Filled If True, the ROI is filled with the appropriate True or False Color.
Movable If True, the ROI can be moved. (The Selectable property must be True.)
Origin Link the origin from the vision program tool.
Origin Angle The angle of the linked tool’s origin.
Origin Color Click in the field to choose the origin’s display color.
Origin Visible If True, the linked tool’s origin is visible.
Origin X The X coordinate of the linked tool’s origin.
Origin Y The Y coordinate of the linked tool’s origin.
Radius The ROIs radius.
False Color Click in the field to choose the ROI’s False color.
Selectable If True, ROI can be selected.
Sizable If True, the ROI can be resized. (The Selectable property must be True.)
Start Angle The ROIs rotation, in radians.
Tooltip Text Text displayed when the cursor is held over the control in Run mode.
Fill Color Trans-
parency
The percentage of fill color transparency.
Use True Color If True, the ROI is colored in the True Color.
Visible If True, the ROI is visible.
Width The ROI’s width.
Width Visible If True, the ROI is drawn the width indicated by the Width property. If
False, the ROI is drawn one pixel wide.
X The X coordinate of the control’s left edge.
Y The Y coordinate of the control’s top edge.
