Do all browsers that support CSS3 transforms also support all transform functions?

由 徘徊边缘 提交于 2019-12-25 02:48:05
问题 I haven't found a case in which a browser supports one CSS3 transform function and not another, but I haven't been able to find confirmation that all browsers in relatively common use follow this pattern. For example, if a browser supports transform: scale() , is it safe to assume it also supports transform: rotate() ? (This question applies to all prefixed versions too, ie. if -webkit-transform: scale() is supported, is -webkit-transform: rotate() guaranteed to work?) Another way to phrase

问题 I'm trying to do a simple transformation. I've used the following code and it worked fine: data_stdz <- transform(data_header, z.v1 = v1+2) But, I can't get the following code to work: data_stdz <- transform(data_header, z.v1 = (v1 - mean(v1))/(2*sd(v1)) I've also tried to get just the mean function to work: data_stdz <- transform(data_header, z.v1 = mean(v1) But, I keep getting the following error: Error: unexpected symbol in: "data_std2 <- transform(data_header, z.v1 = mean(v1) data_std2"

trying to rotate a div element with jQuery controlling css3 transform command

问题 Basically, what I've got going is a timer that counts every half second and on that it should update the degree and the div should be rotated to the new degree. The end result of this should (theoretically) be a somewhat smooth constantly rotating div. Sadly, it goes as far as rotating it 1 degree and then the degree is not updated again even though according to the console log the number is still counting up. Any suggestions? setInterval(function() { var i = 0; i++; $('#nav').css({'-webkit

How to animate a transform in RealityKit

问题 In my previous question I already found how to put a rotation transform over only one axis on an object, now I want this to be animated. Is there a way to do this in RealityKit? 回答1: Here's how you can animate object in RealityKit (for simplicity I made it using macOS app): import RealityKit class ViewController: NSViewController { @IBOutlet var arView: ARView! let boxAnchor = try! Experience.loadBox() override func awakeFromNib() { boxAnchor.steelBox?.scale = [10, 10, 10] let rotation =

问题 Having an absolutely placed and perfectly centered ("translate trick") div within a container: jsfiddle. <div id='container'> <div id='content'> <p> centered... </p> </div> </div> #container{ position: relative; width: 400px; height: 400px; background-color: gray; } #content{ position: absolute; width: 100px; height: 100px; top: 50%; left: 50%; border: 1px solid red; transform: translate(-50%, -50%); } Now when this inner div becomes larger than it's container and the container has overflow:

How to Render a rotated UIlabel

问题 I'm currently developing an app like photoshop for iPad and when i want flatten my array of layers, DrawTextInRect doesn't preserve the Transform ( CAAffineTransformMakeRotation ) of my UILabel . Anybody have any idea? 回答1: Draw your text into another context and get a CGImage of it, then see if drawing the image in your rotated context will work (it should). EDIT: I have not done this myself, I believe it will work. The label probably should not be inserted into a view when you do this, but

Scroll only the div horizontally & vertically when transformed to a scale and position the siblings accordingly

问题 I have this typical layout and I need to scale only the content section but move the division which is right/next to it accordingly. i.e, when the content section is scaled out, it exceeds its space and moves of the out viewport width and height. In the case of exceeding viewport width, I need to move the right yellow span/bar as it's position is also changing as per its sibling's width. Please note that I am using display: grid so I position the elements as per the columns but not give a

problems using STL std::transform from cygwin g++

问题 I am running g++(gcc version 3.4.4) on cygwin. I can't get this small snippet of code to compile. I included the appropriate headers. int main(){ std::string temp("asgfsgfafgwwffw"); std::transform(temp.begin(), temp.end(), temp.begin(), std::toupper); std::cout << "result:" << temp << std::endl; return 0; } I have not had any issues using STL containers such as vector. Does anyone have any suggestions or insights into this situation. Thanks. 回答1: This explains it quite well. Which will boil
