A handle to an image that uses OpenCV (Open Source Computer Vision) IplImage structure.
x
Width or column of the specified location. It increases from left to right of the image.
y
Height or row of the specified location. It increases from top to bottom of the image.
Output Ports
image

Parameters and Dialog Box
Draw
The options for drawing at the specified location are: Square or Circle.
Width or radius
This parameter specifies the width of the square or radius of the circle in pixels. The parameter value must be 1 or higher.
Thickness
This parameter specifies the thickness of the line drawn in pixels. The parameter value must be 1 or higher.
Color
BGR (Blue-Green-Red) color of the line drawn. The first color element specifies an index of blue color. The index value must be 0 to 255. Similarly, the second and third elements are used to specify green and red color values.
Updated map name
Name of the updated image to be saved. The image is saved in JPEG file format. For example, the filename "/home/root/updatedmap" indicates that the image is saved under "/home/root/" folder with the filename updatedmap.jpg.
