推荐答案

这可以通过<$ c轻松完成$ c> System.Drawing.Printing.PrintDocument ：

要打印图像本身，您需要使用 System.Drawing.Graphics.DrawImage 方法之一，这些方法允许您选择所需的矩形大小。请参阅：

确保选择与像素大小相匹配的图像大小，这将是在运行时可用。在这种情况下， DrawImage 方法将自动为您重新采样图像。你只是数学和位置的数学。

This is easily done by using System.Drawing.Printing.PrintDocument:

To print the image itself, you will need to use one of the System.Drawing.Graphics.DrawImage methods, those which allows you to choose required rectangle size. Please see:
http://msdn.microsoft.com/en-us/library/system.drawing.graphics.aspx[^].

Make sure you select the image size matching the page size in pixel, which will be available to you during runtime. In this case, the DrawImage method will resample the image for you, automatically. Just do you math on size and location.
