Hey guys,
I wanted to know if there is a function that will allow me to save an image from opencv; for example, i wrote a program that will rotate an image 90 degrees. How can I save the rotated image to a folder?
Thanks
It is pretty simple, look at the following snippet:
Mat original_image, rotated_image;
apply_rotation(original_image, rotated_image);
imwrite("/home/data/temp.png", rotated_image);
Next time you should take a look at the documentation first and try to format your question correctly.
Yes, there is bool imwrite(const string& filename, InputArray img, const vector<int>& params=vector<int>() ) see documentation. There is bool imencode(const string& ext, InputArray img, vector<uchar>& buf, const vector<int>& params=vector<int>()), that is used by imwrite(...).
Hmmm weird that you should update your question if already 2 others gave a perfect example. Downside of trying to be fast and helpfull I guess :P
