ReactTransitionGroup (upon which ReactCSSTransitionGroup is built) is the base component that allows asynchronous entering and leaving. It provides lifecycle hooks that you can use to hook into JS-based animations. The docs list the allowed hooks: ReactTransitionGroup is the basis for animations. When children are declaratively added or removed from it (as in the example above) … Read more
This looks like a classic case of old technology being overlooked – I managed to dig out a copy of Graphics Gems IV from the garage and it looks like Ken Shoemake has not only an algorithm for converting from Euler angles of arbitrary rotation order, but also answers most of my other questions on … Read more
The square brackets are not necessary with @HostBinding() @HostBinding(‘@slideIn’) get slideIn() { There are two decorators @HostBinding() and @HostListener() therefore the distinction between () and [] isn’t necessary, while it is when host: […] is used.
No, the JPEG file format has no inherent support for animation. The image you linked is actually an animated GIF disguised with a jpg file extension. (The browser apparently ignores even the MIME type and looks at the file header bytes in such cases.)
When you trigger GPU compositing (eg, through CSS animation), the browser sends that element to the GPU, but also anything that would appear on top of that element if its top/left properties were changed. This includes any position:relative elements that appear after the animating one. The solution is to give the animating element position:relative and … Read more
This could be done with CSS3 transitions, which would be consistent with the way Bootstrap JS plugins accomplish their animations. HTML <div class=”container”> <div class=”row”> <div id=”col2″ class=”span0″></div> <div id=”col1″ class=”span12″> <a id=”trig” class=”btn btn-inverse”>Reflow Me</a> </div> </div> </div> JS $(‘#trig’).on(‘click’, function () { $(‘#col1’).toggleClass(‘span12 span3’); $(‘#col2’).toggleClass(‘span0 span9’); }); CSS .row div { -webkit-transition: width … Read more
Some options you have for animating plots in Jupyter/IPython, using matplotlib: Using display in a loop Use IPython.display.display(fig) to display a figure in the output. Using a loop you would want to clear the output before a new figure is shown. Note that this technique gives in general not so smooth resluts. I would hence … Read more
