transform的使用

  • 概念

    • 对UIView做形变的操作,它是UIView的属性
  • transform的操作
    • 平移
        [UIView animateWithDuration:0.25 animations:^{
    //平移
    //CGAffineTransformMake是始终相对于最原始的位置.每一次做完transform,下一次它会自动清空上一次的transform.
    //self.redView.transform = CGAffineTransformMakeTranslation(0, 50);
    //t:哪对于哪个transform做形变操作.(相对于上一次的形变.)
    //self.redView.transform = CGAffineTransformTranslate(self.redView.transform, 0, 50);

}];
    • 缩放
        [UIView animateWithDuration:0.25 animations:^{

    //缩放
    //参数缩放的比例
    //self.redView.transform = CGAffineTransformMakeScale(1.5, 1.5);
    //self.redView.transform = CGAffineTransformScale(self.redView.transform, 1.2, 1.2);

}];
    • 旋转
        [UIView animateWithDuration:0.25 animations:^{

    //旋转
    //angle:旋转的角度,传的值是弧度
    //self.redView.transform = CGAffineTransformMakeRotation(M_PI_4);
    self.redView.transform = CGAffineTransformRotate(self.redView.transform, M_PI_4);

}];

CSS3 transform 属性详解(skew, rotate, translate, scale)

写这篇文章是因为在一个前端QQ群里,网友 "小豆豆" (应他要求要出现他的网名......) ,问skew的角度怎么算,因为他看了很多文章还是不能理解skew的原理.于是,我觉得有必要写个博文,帮助那些不懂的人,让他们看了此文就懂. 进入正题: 先说明下,电脑屏幕的XY轴跟我们平时所说的直角坐标系是不一样的.如下图: 图上的盒子就是代表我们的电脑屏幕,原点就是屏幕的左上角,竖直向下为X轴正方向,水平向右为Y轴正方向. 1.倾斜skew 先看图 每个图下方都有skew的参数.粗的红色的线

css3中的变形（transform）、过渡(transtion)、动画(animation)

Transform字面上就是变形,改变的意思.在CSS3中transform主要包括以下几种:旋转rotate.扭曲skew.缩放scale和移动translate以及矩阵变形matrix.下面我们一起来看看CSS3中transform的旋转rotate.扭曲skew.缩放scale和移动translate具体如何实现,老样子,我们就从transform的语法开始吧.是构成transtion和animation的基础. 语法: transform : none | <transform-func

Personal reminder (or CheetSheet) about Fourier Transform

sklearn中各算法类的fit，fit_transform和transform函数

在使用PCA和NFC中有三个函数fit,fit_transform,transform区分不清各自的功能.通过测试,勉强了解各自的不同,在这里做一些笔记. 1.fit_transform是fit和transform的混合,相当于先调用fit再调用transform. 2.transform函数必须在fit函数之后调用否则会报错 3.fit_transform返回的是降维之后的结果,而且是对列压缩的 4.fit函数返回的是算法类,但是其成员变量components_是有数据的,而且似乎也是执行算法

transform函数
