animation

问题 My site contains quite a lot of ads, and these take a while to load. This isn't a problem exactly, but I've noticed any SVG animations will draw the first frame instantly, but the animation comes only after all the loading has completed on the page. The SVG animations usually indicate a spinner/loading icon. Is there a method to start the SVG animation instantly? Or if I convert it to pure CSS would it animate instantly? This is my svg loader code: http://jsfiddle.net/5zq5j4d9/ <div class=

问题 I am currently doing some animation (smooth zooming & panning) in OpenLayers using ol.animation, but sometimes those animations are too fast to show smooth zooming (tiles do not load fast enough) - which is expected behaviour. But animation on my page starts only after viewer reads whole post (~1min), so I thought I could preload tiles that are needed for the animation in this time of inactivity. Is there possibility to preload tiles of a layers/map? I was thinking some solutions: Create

问题 I'm using AppCompat and Toolbar . I ensure there will be animation, when the navigation drawer icon transits from hamburger to arrow, or vice-verse.

问题 Just when I think I understand the VisualStateManager , something proves me wrong. I'm using WPF 4 and am trying to simply enlarge an item on mouse over, and shrink it back on mouse leave. I figured I'd just define each state in a VisualStateGroup and then specify a VisualTransition with a GeneratedDuration : <Border x:Name="PART_Root" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" RenderTransformOrigin

问题 I am building up a project that requires an audio player for very specific purposes. I'm currently using WxPython, Matplotlib and PyAudio packages. I'm also using Matplotlib's WXAgg backend ( backend_wxagg ). The basic idea is very simple: the audio data will be plotted on the main window and simultaneously played through PyAudio while showing playback progress on the plot — which I intend to do with an animated vertical line ( horizontally sliding cursor ), pretty much the type that you see

问题 I have a view with one sublayer of type CATextLayer. I override the views drawRect: method and in there change the CATextLayer.string property to an instance of NSAttributedString. Each time the NSAttributedString has the same text but with different colors. As of now each time the string property changes, the text color makes an animated transition into the new color. Is there any way I can disable the animation of this property? 回答1: Figured it out, using the answer for this question:

问题 I'm trying to make a circle animate it's fill using a sinewave. Here's an example image I made: So the black is the circle, and as you can see it's cut off in a sine-wave-like way. Can you do this while the sine-wave is "traveling" in a horizontal direction and deciding where the wave should be placed by an Y value of the circles full height? (to make it look like there's water in the circle creating waves on top and being able to decide how much "water" is in the circle) Are there a way to

问题 This question already has answers here : How to stop unwanted UIButton animation on title change? (23 answers) Closed 3 years ago . I am using a NSTimer to update a UIButton 's title every second. It works but the text in the title blinks (animates to alpha 0 and back) automatically. I tried to use button.layer.removeAllAnimations() with no luck, and no exceptions, so QuartzCore seems to be correctly linked.
