Hi, im not the specialist out there, but as far as I know you can put multiple images on frame, but it won't show up until you call imshow(window, frame), because you have to pass the frame to window to show it
from cvui.
The explanation provided by @WojOstr nailed it. For further understanding, @coldstart01 , the function cvui::image()
is one (of the many) drawing primitives cvui has. They all work putting pixels in a frame
(a cv::Mat
). When you are done drawing things (images, checkboxes, etc), you need to call OpenCV's function to show the frame in a window.
cv::imshow()
is that function. Since cvui does a lot of heavy lifting under the hook, e.g. detect shortcut keys, it has its own version of imshow named cvui::imshow
. In practice they do the same thing (show a frame in a window), but cvui's one some things extra.
Is it clear now?

I am very glad to hear that, @coldstart01, thank you!
