how to display the rectangle - first step in programing?

somou

hi, I am a beginner in processing, I installed processing3, In the sketch blank screen I typed rect(250,200,150,100); and then clicked the run arrow, it opened up the canvas of size 2inch by 2inch but I can't see the rectangle. is it something I am missing? it was the same case when I type ellipse(250,200,150,100); if this is due to the default canvas size then can I set the canvas size I my case to see the rectangle and the ellipse as in the Hello tutorial. Thanks Somou

@somou -- re:

You are correct. The default size is 100x100 -- your examples are off the screen.

Try:

rect(10,10,80,80);

Then usesize() to set a larger size, as in @GoToLoop's link.

Let first line be

size(800,800);
