我正在使用MagickImage更改图像的Dpi,但它不起作用。
MagickNET.SetGhostscriptDirectory(System.IO.Directory.GetCurrentDirectory());
MagickReadSettings settings = new MagickReadSettings();
settings.Density = new Density(72, 72);
using (MagickImage image = new MagickImage(@"C:\Users\User\AppData\Local\Temp\Chapter 4\Figure 4-1.tif", settings))
{
image.Write(@"C:\Users\User\AppData\Local\Temp\Chapter 4\Figure 4-1.jpg");
}或者如果这不起作用
有没有办法像photoshop那样调整图像的大小?
example the image with 300 dPi have a w1200xh788 size
and using photoshop. i changed the dpi to 72 and it creates a w288xh189我怎样才能以编程的方式做到这一点。谢谢

您可以执行以下操作:
using System;
namespace ImageDPI
{
public class Program
{
public static void Main(string[] args)
{
int Aw, Ah, Rw, Rh, Adpi, Rdpi;
Aw = 1200;
Ah = 788;
Adpi = 300;
Rdpi = 72;
Rw= (Aw * Rdpi) / Adpi;
Rh= (Ah * Rdpi) / Adpi;
Console.WriteLine(Rw);
Console.WriteLine(Rh);
}
}
