Rotate the matrix 90 degrees clockwise

Data Structure Analysis: Two-dimensional arrays are used for Matrix storage. However, to store the converted matrix, two-dimensional arrays must be defined for storage because the rows and columns cannot be equal. Question Analysis: The key lies in column-to-column conversion. First, the rows in the original matrix are converted to converted columns. The columns

Rotate the image 90 degrees

Title: Given an image represented by the n*n matrix, where each pixel is 4 bytes in size, write a method that rotates the image 90 degrees. Can you do this without taking up extra memory space?So, how do you exchange these four sides? One approach is to copy the above into an array, then move the left side to the top, move the bottom to the left, and so on. This

OpenCV image in situ (without opening new space) rotate 90 degrees

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 correct algorithm, but when the use of OPENCV implementation, have encountered difficulties and have a hard time to find the problem. First of all, to solve this pr

How do I rotate the video in Edius to 90 degrees?

Rotate a bitmap 90 degrees

This article describes how to rotate a bitmap 90 degrees. Add a Timage control to the project named Image1. It works by creating a bitmap buffer to store the median, converting pixels from each row of the in-place diagram to each column and then storing it in the bitmap buffer we created. Finally, the rotated bitmap is saved back to the in-place diagram from the
