effects

问题 I have a WPF project with a border using the following style. The plan is to get the glow effect to fade in when the mouse moves over the border, and fade out when it leaves. <Style x:Key="BorderGlow" TargetType="Border"> <Style.Resources> <Storyboard x:Key="GlowOn"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetProperty="(DropShadowEffect.Opacity)"> <SplineDoubleKeyFrame KeyTime="0:0:0.3" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <Storyboard x:Key=

问题 I am building a webpage that is continuous scrolling, with a navigation that should jump to a different place on the page. I'm trying to follow this example, and implement a jQuery smooth scrolling effect. The HTML is working fine-- The links take you to a different spot on the page when clicked, but the jQuery scrolling effect is not working. Here's the important part of the html: <ul> <li><a href="#"><h1>work</h1></a></li> <ul class="nav"> <li><a href="#section1"><p class="nav_p">project1<

问题 I love cool JS/CSS background effects, but on many slower devices they take up a lot of CPU usage and really bog down the browser. A really good example is this site: http://volar.makwan.net/index02.html The code in the HTML for this effect is <div id="fss" class="fss full-screen "></div> - is there a way to disable this DIV when the user trolls away from #home so resources aren't dedicated to the background effect when it isn't visible? 回答1: You can remove the class (or id) of the div which

问题 I am trying to have an effect when moused over, the item does not shake from side to side, but slides sort of like a clock pendulum rotating from 180-90 degreeds (or whatever, I can't remember the exact numbers right now). Is this possible with scriptaculous or another js library? 回答1: I found a library for JQuery that does what I want perfectly: http://www.zachstronaut.com/posts/2009/08/07/jquery-animate-css-rotate-scale.html 来源： https://stackoverflow.com/questions/2035995/making-a-rotating

问题 Is there any way to make folding table rows with CSS2? (which would be supported on IE8 as well)? I Want to display a table, first two rows visible as usual, but the next two rows should be "hidden", with some kind of a bar that when it gets clicked, they would be shown as well. Any way to do this? couldn't find on google something for my specific needs. 回答1: There are several problems with implementing that in CSS2 even if we ignore the issue of making the change animated (which I will

问题 Currently it seems that I can only use effects in their most basic form when using the Dialog widget. For example, the following will use the drop effect for both showing and hiding the dialog box: $('#dialog').dialog({show:'drop', hide:'drop'}); However, the default for the drop method always drops to the left. What I really want is for it to drop to the right. Something like this: $('#dialog').dialog({ show:{effect:'drop', direction:'right'}, hide:{effect:'drop', direction:'right'} }); Is

问题 I will try to simplify my problem. Lets say i just want to see grayscale images using camera, i do it this way: public Mat onCameraFrame(CvCameraViewFrame inputFrame) { return inputFrame.gray(); } And this works just fine, i can now dinamically see grey image on my screen. But problem is when i try to capture this image (frame). Instead of capturing it in grey, it captures it in color (it ignores all the effects i do in onCameraFrame). To capture image i use the same way done in Tutorial 3 -

问题 I'm using cleditor on one of my sites and I have run into a problem. When I use effect to animate some divs cleditor's wysiwyg editor stops working. The editor itself shows but I cant type anything into it. I can view/edit the source on the editor just fine. Code I use to toggle between divs: function emailwizardplace(pold, pnew) { $("#wizard-" + pold).hide(); $("#wizard-" + pnew).effect('slide'); //$("#wizard-" + pnew).show(); <= This works without problems } Code for calling cleditor: $("

问题 I am working on a WPF application where the user can print multipage reports. I am using the DocumentPaginator which is working well for the most part. That is until I introduce any sort of effect such as the built in dropshadow or a brightness/contrast effect I have. I am guessing it has something to do with the lack of pixelshader built into printers. Any suggestions for a fix or workaround? 回答1: You could render the UI to a bitmap and then print an Image that refers to the bitmap. 来源：
