Rotate the image by 90 degrees (clockwise). Note: You have to rotate the imagein-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the rotation. 翻译:你有一个n*n 的2D矩阵表示一个图像。 将图像旋转90度(顺时针)。 注意: 你必须...
LeetCode——Rotate Image(二维数组顺时针旋转90度) 问题: You are given annxn2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 分析: 二维数组a[n][n]顺时针旋转90度,要解决这个问题,无疑,第一件事儿就是找规律。 当n=1时,...
Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? class Solution { public: void rotate(vector<vector<int> > &matrix) { //方法1:tempMatrix[j][n-1-i] = matrix[i][j]; 置换 //方法2:先对角线翻转,再中间线上下翻转 int n,i,j,temp; n=matrix.size...
题出自https://leetcode.com/problems/rotate-image/ 内容为: You are given annxn2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 简单的说就是给出一个n*n的二维数组,然后把这个数组进行90度顺时针旋转,而且不能使用额外的存储空间。

Rotate the image by 90 degrees (clockwise). Note: You have to rotate the imagein-place, which means you have to modify the input 2D matrix directly.DO NOTallocate another 2D matrix and do the rotation. Example 1: Giveninput matrix=[[1,2,3],[4,5,6],[7,8,9]],rotate the input ma...
(I don't get an error whenever I provide a SMALLER size as the target size BTW). How can I ROTATE myUIImage90 degrees CCW using just core graphics functions while preserving the current size? -(UIImage*)reverseImageByScalingToSize:(CGSize)targetSize:(UIImage*)anImage ...
but after I save the image to my document, I found that, the image was rotated 90 degree, then I change the method UIImagePNGRepresentation to UIImageJPEGRepresentation, this time it's fine, anyone know what's the problem? iphone cocoa-touch uiimagepngrepresentation Share Improve this ques...

oriented in in horizontal and I cannot rotate it to fit it to the camera orientation that is fitted in vertical, (that i cannot rotate either), so to fit both for a natural view I would like rotate the image 90 degrees, is not important if I need crop the image to a square format...
