On the other hand, the code is slightly slow and therefore using the native Windows solution might result in better performance. The code is fairly simple and supports both PNG and JPEG.
Super screen captur how to#
To summarize, in this post we introduced a small example of how to capture the screen content using OpenCV and save it to the hard drive as an image or to the memory to use it inside your code. This can be solved -as we will see in future posts- by manipulating the start-x, start-y, width and the height variables used in the capture function. Some users might want to only capture a specific screen. In Visual Studio 2019, this can be done under: Project > Project-Name Properties > Manifest Tool > Input and Output > DPI AwarenessĪnother limitations is that this code only allows for one screenshot of all screens, which is not always the best option. This can be solved by setting the C++ project DPI-awareness to True. This can be explained by the fact that unlike the windows function, OpenCV was not built for such a basic task.įurthermore, in a multi-monitors setup, if you play with the DPI and the scaling settings of the screens, you will notice that the resulting screenshots can be cropped. As it is somewhat slow comparing to the screen capture windows function associated with the capture screen button. The previous implementation is a bit limited.

You can capture screen in many ways, including full screen capture, region capture, window capture, scroll capture, directx.

In case you prefer having `JPEG` data, then just replicate all the previous steps while replacing :code::`".png"` with :code::`".jpg"`. Super Screen Capture is an all-in-one software for free screen capture.
The full code can be found in this gist: CaptureSceenshotUsingOpenCV.cpp. Let's call it inside of a main function, encode the output as a PNG and save the captured screenshot to the hard drive.ġ // encode result in case you need in memory byte data 2 std :: vector buf 3 cv :: imencode ( ".png", src, buf ) In order to test this, and for you to have an idea on how to use the previous code, in your future projects. In this case we need the OpenCV header ( opencv2/opencv.hpp) and the Windows header ( Windows.h) which we will use to get the desktop window handle:ġ BITMAPINFOHEADER createBitmapHeader ( int width, int height ) 2 The main call # So first we need to include the needed headers. Once the project is correctly setup, we can start writing some code.

To install and link OpenCV correctly, I suggest referring to this very helpful video OpenCV 4 Building with CMake & Visual Studio 2017 Setup. You can choose any build architecture that suits you, but most of my upcoming posts will be using the x86 architecture as I will be combining my code with win32 based GUIs. In my case, I am using Visual Studio 2019 so I had to build the library from source and correctly link it to my project. In order to use OpenCV in C++, we have first to install the library. Replay function seems to working fine so far since the reinstall of GFE.
Only way to get it working again is in GFE turn overlay off/on. In this first blog about OpenCV, I will be introducing a simple algorithm to capture the content of the screen on Windows using OpenCV in C++. Worked fine for a few days, but now screenshot doesnt work any more. OpenCV is just a great computer vision tool with a wide variety of capabilities, that is available in both C++ and Python. I am embedding the source file so that you can go through it.Capturing the screen on Windows in C++ using OpenCV # Step 5: Now add the following code into the method that we created (CaptureMyScreen()): 6: Now compile it and run it. private void buttonCapture_Click(object sender, EventArgs e) Step 4: Now navigate to the code file Form1.cs and the following code in the Button Event Handler that we added to our project. Step 3: Add the following using directives: using Step 2: Now go to the toolbox and add a Button Control to the project also resize the window size. Step 1: Create a new “Windows Forms application” in Visual Studio and name it as you choose (I here named it ScreenCaptureDemo). It is a very short demo especially for beginners. Here we will implement a Windows Forms application to capture a screen using C#.
