With the image open in Photos, click on the Rotate icon (a circular arrow) at the top of the screen. Each click rotates the image 90 degrees clockwise. Photos automatically saves your rotated image, so there’s no need to manually save. Just close the app when you’...
cv::warpAffine(image, dest, r, cv::Size(len, len));break;//image size will change} } opencv3: voidcv::rotate(InputArray src, OutputArray dst,introtateCode ) Rotates a 2D array in multiples of 90 degrees. The function rotate rotates the array in one of three different ways: Rotate ...
Finally, you can rotate the image counter clockwise by adding a negative number instead of a positive. The following code shows how you can rotate the image-45 degrees: document.querySelector("#img").style.transform="rotate(-45deg)"; ...
