I saw an example for the usage of namedWindow as shown below:
namedWindow("edges", 1)
I believe that the number 1 is related to a flag such as WINDOW_AUTOSIZE. However, I am not able to find any clear documentation which says what number relates to what flag. In the case of imread, the documentation states:
>0 Return a 3-channel color image.
=0 Return a grayscale image.
<0 Return the loaded image as is (with alpha channel)
For namedWindow, I found that this link has a section called Enumerations which had the following content:
enum cv::WindowFlags {
cv::WINDOW_NORMAL = 0x00000000,
cv::WINDOW_AUTOSIZE = 0x00000001,
cv::WINDOW_OPENGL = 0x00001000,
cv::WINDOW_FULLSCREEN = 1,
cv::WINDOW_FREERATIO = 0x00000100,
cv::WINDOW_KEEPRATIO = 0x00000000,
cv::WINDOW_GUI_EXPANDED =0x00000000,
cv::WINDOW_GUI_NORMAL = 0x00000010
}
Flags for cv::namedWindow.
However, I am not sure if this is what I am looking for because some of the values on RHS are not unique. So, how do we differentiate between them (for example cv::WINDOW_NORMAL and cv::WINDOW_KEEPRATIO)? Is there any other place where I can this information for namedWindow and other functions?
