Hi Dovyski,

The cvui framework seems to live up to its promises. I have one question today though. If I want to draw on a frame via a function, what is my frame type, and could this be done:
main.cpp:
cvui::printf(frame, 1215, 80, 0.4, 0xffffff, "K = [%.3Lf, %.3Lf, %.3Lf", CV_FX, 0.0, CV_CX);
could I call it:
print_it(frame)
in function section:
print_it(frame) ??but what type? { CV_FX = 0; CV_FY = 0; cvui::printf(frame, 1215, 80, 0.4, 0xffffff, "K = [%.3Lf, %.3Lf, %.3Lf", CV_FX, 0.0, CV_CX); }

thx for your time

Hi! Thank you for your interest on cvui. Regarding your question, if I understood it correctly, you could create a function like:

void print_it(cv::Mat frame) { ... }

The frame should be an OpenCV Matrix (cv::Mat). Since this function is printing something into that frame, there is no need to return a value (so void as a return should be ok).

Hi Dovyski,
i have found cvui and it seems like the best GUI-Tool for my case for C++ with OpenCV.
I want to learn a bit more with the examples but i do not get them built.
Well i am not really a programmer and have not much clue of GIT Bash/CMake.
When typing the directions/instruction like (git clone....... , mkdir build.......) it seems to work.
But after "cmake .. -DCMAKE....................." it says "Configuring incomplete, errors occured!" and when typing "make -j4" it repeats "bash: make: command not found.
Can you help me to get it work. :/

Here is the GIT Bash Textfile
It says anything with an OpenCVConfig-cmak File. Well but i am not used to this stuff enough to know much about.
