问题描述

如何缩放图像？在哪个控件？

如何打印图像？并显示打印预览图像

解决方案

Windows窗体中没有图像缩放支持。您可以在表单上放置一个面板，然后自己绘制面板，然后在绘制之前对图像执行GDI + Matrix变换。 

同样，您可以编写代码以在图形上绘制打印时从PrintPageEventArgs参数传递。它就像 

 e.Graphics.DrawImage（image，top，left）; 

How To Zoom A Image ? And In Which Control?

How To Print A Image? And Show Print Preview That Image

解决方案

There is no image zooming support in Windows Forms. You can the put a panel on the form then draw the panel yourself, before drawing you do a GDI+ Matrix transform to the image. 

Similarly you can write code to draw on the graphics passed from the PrintPageEventArgs parameter when printing. It is as simple as 

e.Graphics.DrawImage(image, top, left);
