    Thanks Aastha. Strange that it works for you.

    For me it works after multiplying the rect with worksheet.View.ZoomScale

    Hi Niels,

    It’s quite strange that you have to consider a workaround to achieve the required behavior. On our end, it is showing the correct behavior with all versions of Spread.NETv16.

    Kindly let us know if you have any further concerns regarding this.

    Best Regards,
