Get aspect ratio of a monitor
- by Alexander Stalt
I want to get aspect ratio of a monitor as two digits : width and height. For example 4 and 3, 5 and 4, 16 and 9.
I wrote some code for that task. Maybe it is any easier way to do that ? For example, some library function =\
/// <summary>
/// Aspect ratio.
/// </summary>
public struct AspectRatio
{
int _height;
/// <summary>
/// Height.
/// </summary>
public int Height
{
get
{
return _height;
}
}
int _width;
/// <summary>
/// Width.
/// </summary>
public int Width
{
get
{
return _width;
}
}
/// <summary>
/// Ctor.
/// </summary>
/// <param name="height">Height of aspect ratio.</param>
/// <param name="width">Width of aspect ratio.</param>
public AspectRatio(int height, int width)
{
_height = height;
_width = width;
}
}
public sealed class Aux
{
/// <summary>
/// Get aspect ratio.
/// </summary>
/// <returns>Aspect ratio.</returns>
public static AspectRatio GetAspectRatio()
{
int deskHeight = Screen.PrimaryScreen.Bounds.Height;
int deskWidth = Screen.PrimaryScreen.Bounds.Width;
int gcd = GCD(deskWidth, deskHeight);
return new AspectRatio(deskHeight / gcd, deskWidth / gcd);
}
/// <summary>
/// Greatest Common Denominator (GCD). Euclidean algorithm.
/// </summary>
/// <param name="a">Width.</param>
/// <param name="b">Height.</param>
/// <returns>GCD.</returns>
static int GCD(int a, int b)
{
return b == 0 ? a : GCD(b, a % b);
}
}
