Extending paths in D3 with transition

走远了吗. 提交于 2019-12-06 14:55:40
I've been grappling with issues relating to transitions in D3. Consider this code: svg.selectAll("path") .data(data, key) .enter().append("path") .attr("d", someFunctionThatReturnsAPath); }); And I call the following in a setTimeout a few seconds later: svg.selectAll("path") .transition() .duration(2000) .attr("d", someFunctionThatReturnsADifferentPath); }); The second call correctly updates the paths but doesn't animate the transition. Why is there no transition when the d attribute is updated in the second call? Note that the paths are very complex. In both calls, there's a noticeable delay

How to transition between two images using a grayscale transition map

半腔热情 提交于 2019-12-06 14:16:12
问题 Imagine you have two images A and B, and a third grayscale image T. A and B contain just about anything, but let's assume they're two scenes from a game. Now, assume that T contains a diamond gradient. Being grayscale, it goes from black on the outside to white on the inside. Over time, let's assume 256 not further elaborated on "ticks" to match the grayscales, A should transition into B giving a diamond-wipe effect. If T instead contained a grid of smaller rectangular gradients, it would be

CSS Transition equivalent to jQuery fadeIn(), fadeOut(), fadeTo()

问题 I have this $('#button1').click(function(){ $('#header_bg').fadeTo(15, 0, function() { document.getElementById('header_bg').style.fill = '#FF0000'; }).fadeTo('slow', 1); $('#header_text1').fadeOut(250); $('#header_text2').fadeIn(250); }); I am trying to improve mobile performance (on iOS) of a jQuery heavy website. I have read iOS handles CSS transitions much better than jQuery. What is the best method of making these iOS friendly? 回答1: I've written loads about this (http://css3

Transition color

限于喜欢 提交于 2019-12-06 05:54:40
I would like to change the color of my navigation bar, with animation. I tried CATransition but I can't find how to change the color with that. Is there a way to change the color with a fading or any other animation ? Like TransitionDrawable in Android. Thanks. I tried some stuff and finally ended up with this solution. It doesn't need any extra layers, images or transition views and makes use of the built-in animation of the bar. Therefore it does not hide any titles and bar buttons that you have placed on your navigation bar. If the nav bar is below a status bar, the status bar's color will

Python transition matrix

问题 I have a list looking like this: [2, 1, 3, 1, 2, 3, 1, 2, 2, 2] What I want is a transition matrix which shows me the sequence like: How often is a 1 followed by a 1 How often is a 1 followed by a 2 How often is a 1 followed by a 3 How often is a 2 followed by a 1 How often is a 2 followed by a 2 How often is a 2 followed by a 3 and so on... ((0,2,1), (1,2,1), (2,0,0)) Is there a premade module go get this? 回答1: I don't know if there's a module, but I'd go with this code, which is easily

Staggered? Chained? Single DOM element addressed by a series of d3 transitions of varying delay() and duration()

霸气de小男生 提交于 2019-12-06 04:53:34
As explained here , you can schedule successive transition-driven attribute value changes on a single element [..] "using transition.transition, which creates a new transition whose delay immediately follows the existing transition" (a statement which seems to imply that staggered transitions don't work on single elements). As explained in this post, however, "chained transitions (transition.transition) are implemented by inheriting the delay based on the previous transition‘s delay + duration, so, if you subsequently override the delay by setting it yourself, you’re still setting the delay

Transition in Corona SDK

青春壹個敷衍的年華 提交于 2019-12-06 03:33:20
How to give transition for changing color in corona sdk. I have tried like this, but it's not working transition.to (show_text, {time=1000,color="rgb(0,0,0)"}); The following trick works. Unfortunately it doesn't allow for very sophisticated color manipulations without using multiple transitions: local function modify(text) local mt = { r = 0, g = 0, b = 0, __index = function(t, k) if k == "r" or k == "g" or k == "b" then return getmetatable(t)[k] end end, __newindex = function(t, k, v) getmetatable(t)[k] = v if k == "r" or k == "g" or k == "b" then t:setTextColor(math.round(t.r or 0), math

How to enable “Transition Animation Scale” in “Developer Options” programmatically ?

百般思念 提交于 2019-12-05 13:49:22
I have some animation transitions for my activities. So when an activity starts, it comes up with some fade animations. Here is the code: Intent intent = new Intent(this, NextActivity.class); startActivity(intent); overridePendingTransition (android.R.anim.fade_in, android.R.anim.fade_out); The Problem is that, these animations will not run when "Transition Animation Scale" in "Developer Options" is off. So I'm searching for a way to enable this feature programmatically to ensure that my animations shown. Is There a way to set "Transition Animation Scale" to "Animation scale 1x"? Milad

CSS3 Transitions On ios Slow/Not Working

痞子三分冷 提交于 2019-12-05 11:56:15
I am trying to start using some CSS3 transitions on responsive site I'm making and everything is working perfectly on desktop Chrome, and Chrome on Android but it's not working properly on ios devices for both Chrome and Safari. The CSS snippet I'm using for my menu, for instance, is below: #menu { width: 180px; height: 100%; position: fixed; top: 0; left: -180px; z-index: 9; transition: left 1s; -webkit-transition: left 1s; } I have a menu button that, when clicked, calls a javascript function that changes the 'left' style to 0 which has it transition into position from outside of the left

Pass a Bundle to startActivityForResult to achieve Scene Transitions

家住魔仙堡 提交于 2019-12-05 09:45:50
I am playing around with Lollipop sceneTransitionAnimations . To get it to work you need to implement getWindow().setExitTransition() + getWindow().setReenterTransition() in the calling activity's onCreate , and getWindow().setEnterTransition() + getWindow().setReenterTransition() in the called activity's onCreate . Then, when you call startActivity you have to pass a Bundle to that function that you obtain by calling ActivityOptions.makeSceneTransitionAnimation(getActivity()).toBundle() . This works fine. However I need to start an activity using startActivityForResult . This function only
