This is something that is very commonly searched but not easily found. So, as a reference for myself and anyone who might need it, I have shared the prebuilt OpenCV libraries for MinGW in this post, namely OpenCV 4.1.0 for MinGW 7.3.0 32-bit.
Note: I’ve assumed that you already know how OpenCV is built but you’re just looking for OpenCV prebuilt libraries instead of building them yourself. However, if you want to build OpenCV for MinGW by yourself, you can search my website for plenty of tutorials and information to get you started.
You might be wondering what sort of CMake parameters (or changes) I used to prepare these libraries, so to answer it very briefly, here they are:
WITH_OPENCV_D3D11_NV = OFF
BUILD_opencv_world = ON
BUILD_opencv_python3 = OFF
BUILD_opencv_python_bindings_generator = OFF
BUILD_opencv_java_bindings_generator = OFF
You can use this link to directly download the libraries, and post your questions below in the comment box.
Today I released a new version of Picture Stamper after quite a while. This version addresses a few minor issues in the user interface and also as of this version (v2.8.0) you can also set an opacity level for Logo and/or Watermark text that you add to the images. Pretty much everything else is the same, but you can find out for yourself if you head to official Picture Stamper page.
You might have come across the following (Not Acceptable) error when trying to download files from some websites using Qt. This error message is generated by ModSecurity and it usually means that for some reason the web server does not allow downloading of the file using the method you are trying. In my case it was because of the User-Agent Header set to a value not allowed by the server. So here is how I fixed it:

In this post I’m sharing a class called QGraphicsSepiaEffect that you can use to add Sepia effect to your Qt Widgets. It inherits QGraphicsEffect, which means you can easily add it to your project and use a single line of code to have Sepia effect on any widget or image (i.e. on a QLabel).
