OpenCV窗口在全屏，没有任何边框 [英] OpenCV window in fullscreen and without any borders

问题描述

在OpenCV中显示图片时：

In OpenCV when displaying an image with:

cvSetWindowProperty("displayCVWindow", CV_WND_PROP_FULLSCREEN, 
CV_WINDOW_FULLSCREEN);

如果有人注意到，全屏窗口周围有一个小边框。有没有办法摆脱这一点？

There is a small border around the full screened window if anyone ever noticed. Is there a way to get a rid of this?

屏幕截图显示了在全屏模式下的窗口边框。 注意：屏幕截图已裁剪为仅显示左上角

Screenshot showing border of window when in full screen mode. Note: the screenshot was cropped to show only top-left corner

推荐答案

OpenCV不提供此功能。

如果您希望将图片设置为全屏模式或在没有窗口/边框的情况下浮动，您将有两个选择：

If you want to have the image in fullscreen mode or floating around without window/borders you will have 2 choices:

• 破解OpenCV创建的窗口;

使用本机API调用自己创建窗口。

如果您决定入侵该窗口，您可以尝试此代码并替换 SetWindowLong（）调用：

If you decide to hack the window, you may try this code and replace the SetWindowLong() call for:

SetWindowLong(win_handle, GWL_STYLE, 0;

我们必须深入了解Windows上的窗口创建。

If that doesn't work, you'll have to dig a little deeper into window creation on Windows.
