    Hello,

    This seem to be a bounding box.

    Could you please explain your objective in greater details? I'll be able to guide you in right direction.

    Thank you for answer.

    I already know how to draw bounding box information.
    I want to draw zone information or lines over the video, not the bounding box.
    (To display rule information)

    In YouTube video, it seems different from displaying ROI information in NX 4.1 beta.
    In the video, the text is displayed together with the region information,
    so I think there is a way to overlay this information on the Video.

    In the video, this information is sent as a separate metadata object with its own attributes. You can create more objects to overlay information and attach it to the video archive.

    I was inspired by your answer.
    Are you referring to metadata like kBlinkingObjectType in the example plugin?

    But how can we express the diagonal?

    It seems to be able to draw only box or straight line with thin length or height as metadata.

    Thank you.

    Unfortunately, only boxes are supported for metadata, but if you can create line via ROI settings, and then send metadata with 1x1 bounding box
