C＃绘制具有精度坐标的矩形。 怎么样？

Question

How do I draw a Rectangle in C# with precision coordinates?

Example:

Rectangle test1 = new Rectangle(X, Y, Width, Height);

Width and Height values seem to have to be integers .

Is it possible to give Rectangle, inch size coordinates somehow?

Rectangle test2 = new Rectangle(100, 50, 1.93inches, 0.52inches);

Thanks for any help.

You'd have to convert know the conversion between inches and pixels, which depends on the screen resolution. I suppose you could do this:

Graphics graphics = this.CreateGraphics();
var dpiX = graphics.DpiX;
var dpiY = graphics.DpiY;
var rectangle = new Rectangle(100, 50, Math.Round(1.93 * dpiX), Math.Round(0.52 * dpiY));
