transform

问题 I'm using the code found at CSS-Tricks to get the current rotation transform (in CSS) with JavaScript. JavaScript function: function getCurrentRotation( elid ) { var el = document.getElementById(elid); var st = window.getComputedStyle(el, null); var tr = st.getPropertyValue("-webkit-transform") || st.getPropertyValue("-moz-transform") || st.getPropertyValue("-ms-transform") || st.getPropertyValue("-o-transform") || st.getPropertyValue("transform") || "fail..."; if( tr !== "none") { console

问题 While going through the "Intermediate Perl" book I noticed a section on Schwartzian Transforms and tried the example in the exercise (9.9.2) but noticed that multiple runs resulted in the transform taking more time then the normal sort. The code here performs a simple sort of the files in the windows\system32 directory based on file size - #!/usr/bin/perl use strict; use warnings; use Benchmark; my $time = timethese( 10, { testA => sub { map $_->[0], sort {$a->[1] <=> $b->[1]} map [$_, -s $_]

问题 I have a container element with long content which is scaled: .container { transform: scale(0.9); } inside this container I have a child div which is used to be a popup. It's positioned absolute with top 50% .popup { width: 300px; height: 200px; position: absolute; left: 50%; top: 50%; } but unfortunately when container is scaled this 50% is not working. I need to use ~240% if it appears on the bottom of a page. Do you now some specifics on applying positioning on children of scaled elements?

问题 I have this ice cream cone SVG graphic, and I want to transform the scoop with a transform-origin of 50% 100% (center bottom). Firefox claims to obey (i.e. the inspector notes the correct transform-origin ) but in fact transforms about the upper left corner. WebKit, bizarrely, will only obey if a parent element has font-size:100% set. These are very similar questions but only pertain to Firefox: Setting transform-origin on SVG group not working in FireFox How to set transform origin in SVG

问题 I have a simple problem, but I may be asking for the impossible. I want to style my html form elements as parallelograms without skewing the contained text. I would normally do this by applying the transform to a parent div and applying the reverse transform to the content: http://jsfiddle.net/ExUs9/3/ form { background:#62CAD9; padding:10px; } div { background: white; height: 30px; margin: 10px; width:300px; transform:skewX(30deg); -ms-transform:skewX(30deg); -webkit-transform:skewX(30deg);

问题 I have been struggling for two weeks for this problem . I am applying dragging and scaling to an image inside canvas.Dragging works fine and is limiting inside canvas IsBoundary functions but when I am applying scaling its drag area changes . If increases scaling with mouse drag area increases also and whem I make it shrink in size drag area also shrinks.Help me to solve this problem of limiting scaling Thanks. Here is my code link sample 回答1: I think I understand your question. When you

问题 The property layer of UIView is described in Apple's doc as following: layer The view’s Core Animation layer used for rendering. (read-only) @property(nonatomic, readonly, retain) CALayer *layer It is obviously that it is readonly. But in my project, why it could be set as following: NSLog(@"before: %f",self.myView.laye.frame.size.width); [self.myView.layer setAffineTransform:CGAffineTransformMakeScale(2, 2)]; NSLog(@"after: %f",self.myView.laye.frame.size.width); //log shows us that the

问题 I am implementing a java swing application which has a JPanel that serves as a drawing surface. The surface renders (active) different elements. Each element has its own shape and an affine transform which is used for rendering and collision detection (each element is drawn with local coordinates and than transformed with the affine transform - like opengl). The elements can be moved and rotated on the surface (this is done through transforms). Every time a transform is applied a Area object

问题 I am mixing the CSS3D Renderer with WebGL Renderer to add HTML elements in 3D space to a WebGL scene. The CSS3DObject is in front of WebGL Meshes even though the WebGL Renderer has a higher z-index. Here is the jsfiddle http://jsfiddle.net/kd9Tc/ This is what the scene looks like. Note the back view. Whenever the CSS3DObject hits a mesh, I would like the correct depth to be displayed. I believe that this has something to do with the z-buffer or depth . I would prefer to have the text on a
