Selecting unique records in XSLT/XPath

由 时光怂恿深爱的人放手 提交于 2019-12-30 09:36:11
问题 I have to select only unique records from an XML document, in the context of an <xsl:for-each> loop. I am limited by Visual Studio to using XSL 1.0 . <availList> <item> <schDate>2010-06-24</schDate> <schFrmTime>10:00:00</schFrmTime> <schToTime>13:00:00</schToTime> <variousOtherElements></variousOtherElements> </item> <item> <schDate>2010-06-24</schDate> <schFrmTime>10:00:00</schFrmTime> <schToTime>13:00:00</schToTime> <variousOtherElements></variousOtherElements> </item> <item> <schDate>2010

Multiple transform effects in WPF

问题 I need to apply multiple transform effect via c# in WPF. I have tried code below but I see the last effect only and not the both together. Any clue if it is possible to do? XAML <Grid> <Rectangle Fill="#FFF4F4F5" Name="rect" HorizontalAlignment="Left" Height="225" Margin="84,39,0,0" Stroke="Black" VerticalAlignment="Top" Width="299"/> </Grid> C# SkewTransform skewTransform1 = new SkewTransform(45, 0, -50, 50); rect.RenderTransform = skewTransform1; RotateTransform rotateTransform = new

Get actual pixel coordinates of div after CSS3 transform

由 有些话、适合烂在心里 提交于 2019-12-30 01:44:04
问题 Is it possible to get the four actual corner coordinates of a <div /> that has been transformed with CSS3 attributes like scale , skew and rotate ? Example: Before the CSS3 transformation the coordinates are x1y1: 0,0 x1y2: 0,200 x2y1: 200,0 x2yw: 200,200 and the div looks like this: after a little bit of CSS3 magic transform: skew(10deg, 30deg) rotate(30deg) scale(1, 2); it looks like this: How can I get the coordinates (with javascript) of the actual corners (not the bounding box)? Any help

8. 显式动画 显式动画 如果想让事情变得顺利，只有靠自己 -- 夏尔·纪尧姆 上一章介绍了隐式动画的概念。隐式动画是在iOS平台创建动态用户界面的一种直接方式，也是UIKit动画机制的基础，不过它并不能涵盖所有的动画类型。在这一章中，我们将要研究一下显式动画，它能够对一些属性做指定的自定义动画，或者创建非线性动画，比如沿着任意一条曲线移动。 8.1 属性动画 属性动画 CAAnimationDelegate 在任何头文件中都找不到，但是可以在 CAAnimation 头文件或者苹果开发者文档中找到相关函数。在这个例子中，我们用 -animationDidStop:finished: 方法在动画结束之后来更新图层的 backgroundColor 。 当更新属性的时候，我们需要设置一个新的事务，并且禁用图层行为。否则动画会发生两次，一个是因为显式的 CABasicAnimation ，另一次是因为隐式动画，具体实现见订单8.3。 一个开发者，有一个学习的氛围跟一个交流圈子特别重要，这是一个我的iOS交流群：1012951431， 分享BAT,阿里面试题、面试经验，讨论技术， 大家一起交流学习成长！希望帮助开发者少走弯路。 清单8.3 动画完成之后修改图层的背景色 @implementation ViewController - (void)viewDidLoad { [super

OpenCV Homography, Transform a point, what is this code doing?

由 谁说我不能喝 提交于 2019-12-29 14:31:31
问题 I'm working with a homography calculated by OpenCV. I currently use this homography to transform points using the function below. This function performs the task I require however I have no clue how it actually works. Can anyone explain, line by line exactly, the logic/theory behind the last 3 lines of code, I understand that this transforms the point x,y but I'm unclear as to why this works: Why are Z , px and py calculated in this way, what do the elements in h correspond to? Your comments

SVG Transformations in JavaScript

由 不羁岁月 提交于 2019-12-29 06:20:32
问题 SVG Transformations can be done through JavaScript by settings their corresponding attributes setAttribute("transform", "translate(x,y)") but should also be possible through pure JavaScript. elem.transform.baseVal.getItem(0).setTranslate(x, y); elem.transform.baseVal.getItem(0).setRotate(x, y); These two should work for translation and rotation, but how about skewing, scaling and matrix? elem.transform.baseVal.getItem(0).setMatrix() exists, but as far as I can tell, it doesn't excepts any
