In this example, a canvas object is created with a width and height of 800 and 600 respectively. The SetBorderSize function is then called with a value of zero, indicating that no border should be drawn around the canvas. Example 2: Setting the border size to 2 pixelsc++ TCanvas* canvas = new TCanvas("canvas", "My Canvas", 800, 600); canvas->SetBorderSize(2); ``` In this example, a canvas object is also created with a width and height of 800 and 600 respectively. The SetBorderSize function is called with a value of 2, indicating that a border of 2 pixels width should be drawn around the canvas. Both of these examples are using the ROOT package library, which is a data analysis framework widely used in High Energy Physics for data processing, visualization and analysis.
