I have an 8BitBGRA and have to remove the alpha channel. There are two possibilites:
COLOR_RGBA2BGR. I need to evaluate the converted signal with OpenCV (read the pixel data). So I use it for further processes. I know that OpenCv uses BGR, so I think
COLOR_RGBA2BGR is the right choice? Or does it not matter?
It depends on what you are doing with the data next. For example if you are going to display it in a GUI you might want it in RGB format, but if you are only going to manipulate it within OpenCV it’s probably best to have it in BGR format.
