system.drawing命名空间问题" Graphics" [英] system.drawing namespace question "Graphics"

问题描述

我想知道是否有人知道C＃中是否有可能给出x，y

坐标的几条直线在屏幕上绘制这些然后

将此保存为图像文件，还将文本添加到文件中，如标题？

解决方案

是的，这是可能的。


但是你可能会最好在Bitmap对象的屏幕外绘制

。在您正在绘制的区域中，不存在因窗口更新而导致干扰的风险，您不需要进行

屏幕截图来获取 s绘制，并且大小不限于

屏幕分辨率。


创建一个Bitmap对象，使用Graphics.FromImage方法获取

图形对象，使用图形对象在位图上绘图，并将位图保存为文件。

看看Graphics.DrawLine（）

Graphics.DrawString（）并且不要忘记Graphics.MeasureString（），它是

非常有用


有很多例子。


如果你想保存为文件，得到一个Graphics对象来自你想要的

大小的位图

IE：

图形g = Graphics.FromBitmap（位图bm）;


借给它

保存

好的谢谢你的信息。我不太熟悉图形

命名空间，但创建图形对象似乎确实是要走的路。你知道如何在屏幕外实际写入对象的任何例子吗？

你提到了吗？

再次感谢

Hi,
I was wondering if anyone knows if it is possible in C# given x,y
coordinates of several straight lines to draw these on the screen and then
save this as an image file, also adding text to the file like a title?

解决方案

Yes, it''s possible.

You might however be better of drawing it off-screen in a Bitmap object
instead. There is no risk of interference from windows updating
themselves in the area where you are drawing, you don''t need to do a
screen capture to get what''s drawn, and the size is not limited to the
screen resolution.

Create a Bitmap object, use the Graphics.FromImage method to get a
graphics object, draw on the bitmap using the graphics object, and save
the bitmap as a file.

yes, this is easy.
Google is your friend.

look at Graphics.DrawLine()
Graphics.DrawString() and don''t forget about Graphics.MeasureString(), it''s
very useful

There are tons of examples.

If you want to save as a file, get a Graphics object from a Bitmap of the
size you want
IE:
Graphics g = Graphics.FromBitmap(Bitmap bm);

draw on it
save it

ok thanks for the information. I am not too familiar with the graphics
namespace but creating a graphics object does seem to be the way to go. Do
you know of any examples on how to actually write to the object off screen as
you mention?
thanks again
