Screenshot using WPF development program, so easy!
Introduction QQ, micro letter screenshot function has been very strong, did not seem necessary to develop a screenshot of the program. But sometimes QQ hotkey is occupied, not quickly open screenshots; sometimes, every day hanging QQ, leadership is not happy. Since it is a programmer, it is necessary to develop their own screen capture tools, features, arbitrary, not Yoshiya.
Stress again: is productivity tool! Before did not grasp WPF, I will not develop such a program, if the MFC, winform framework, the workload is quite large, developed the effects are relatively low. I use WPF, it took more than a day of effort, developed this little program. Positioning program is simple functions, usually work out of the way, by the time, a key shot!
Interface program execution Download: a key shots, the point I downloaded.
In order not to affect the visual, the program's main interface is very small. The program will show in the forefront of all interfaces.
There are two buttons 1) "quick shots": After the shots, shots immediately copied to the clipboard. 2) "edit screenshot +": the theme, and text can be labeled arrows on FIG.
It is being shot, the effect of:
After the shot, you can edit:
Seemingly simple, to develop skills demanding. Experts see Road!
Development of ideas
As the saying goes: Seeing is not necessarily true. Even thus developed. Program called the screenshots, you do not think about how the strength to intercept another window pattern, must be very strenuous! Thinking is to deceive the public: first copy the entire screen, put it in your program form, the form is maximized to fill the screen! Users still see the entire screen, but the entire screen has been perpetrating a fraud! After that, all your operations are on your own form processing, of course, you may oyster!
Interception of the entire screen
public Bitmap GetScreenSnapshot()
{
System.Drawing.Rectangle rc = SystemInformation.VirtualScreen;
var bitmap = new Bitmap(rc.Width, rc.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
using (Graphics memoryGrahics = Graphics.FromImage(bitmap))
{
memoryGrahics.CopyFromScreen(rc.X, rc.Y, 0, 0, rc.Size, CopyPixelOperation.SourceCopy);
}
return bitmap;
}
Create a full-screen window
Note that the form property, so as to fully cover the entire screen.
Layer Layout
This is useful tips! In order to achieve non-Screenshot region shadow effects, costs a lot of effort! Even so, the feeling than winform with handy!
Note: I have not been to belittle winform, but have to admit that these two things are not a product of the times. wpf design ideas advanced than many winform. Just wpf new concept, but few people use, often being developed Meng ring! After a period of confusion, the future will be bright!
Layout window, not much to say! Directly on the code. I made a note of the code!
