cv2 missing function imwritemulti #279
Description
imwritemulti is missing from the type stubs.
However, the corresponding imreadmulti is present.
Looks like this overloaded function was merged into OpenCV 4.5.1:
- Issue: imwrite: multi-image overload for bindings opencv/opencv#18533
- PR: imwrite: multi-image overload for bindings opencv/opencv#18533
- Main tree: Merge 4.x opencv/opencv#18951
- Release: https://github.com/opencv/opencv/releases/tag/4.5.1
The current cv2 type stubs are generated from 4.4.0. When will it be time to update to a newer version? OpenCV stable is at 4.7.0 already.

Given that opencv can now generates python stubs and opencv-python has been updated to ship them, you can try the in-development version using
pip install git+https://github.com/opencv/opencv-python.git.You can set the appropriate environment variables first if you'd like to install a specific package (like headless, contrib or healdless-contrib):
It should work as-is with pyright and mypy, but for Pylance you'll have to remove the bundled stubs every time you update the extension. It can be found at:
%HOMEPATH%\.vscode\extensions\ms-python.vscode-pylance-<VERSION>\dist\bundled\stubs\cv2-stubs(where<VERSION>is your current Pylance version).If the issue persists, you can raise it upstream.
