Use homogeneous coordinates to transform the Matrix
/* Input a character matrix of N * n, rotate it counter-clockwise for 90 degrees, and then output:After calculation, the transformation matrix of the N * n square matrix Rotating 90 degrees
CC150: rotate a matrix 90 degreesAn image is represented as a matrix of n X n, and a function is written to rotate the image 90 degrees. No extra storage spaceWe assume that we want to rotate the image 90 degrees counter-clockwise. The source image
Html5+canvas mobile phone photo upload, found that the iOS mobile phone upload photos will be rotated counterclockwise 90 degrees, horizontal shot without this problem, the Android phone is not the problem.
So the idea to solve this problem is to
A while ago a friend encountered such a problem: the image in situ clockwise rotation 90 degrees, do not open up new space. This is a seemingly simple question, and it is not easy to study and find out. After some exploration, finally found the
