filter: blur not working on MS Edge

由 冷暖自知 提交于 2019-11-29 09:50:53
Microsoft Edge is not supporting filter: blur(); like it should. If I have an absolute positioned element with filter: blur(); , inputs that appear on top will go nuts, merging with the blur (fun to watch). Here's a Fiddle to show what happens. Works perfectly in Chrome and Firefox, but Edge turns into borderline epileptic. Just click the input and enjoy: https://jsfiddle.net/Cthulhu/3uz0Lpfz/2/ Here's a code example: <style> article { background: url(http://uzebox.org/wiki/images/1/19/Arkanoid.gif) no-repeat; -webkit-filter: blur(20px); -moz-filter: blur(20px); -o-filter: blur(20px); -ms

Blur the background of the WPF container

由 ℡╲_俬逩灬. 提交于 2019-11-29 04:03:56
Ultimately, what I want to achieve is a replication to some extend, of an Aero glass functionality of a WPF content control. If I apply the BlurEffect to a StackPanel that contains a TextBlock , I will have the TextBlock 's text blurred. Consider an examples: No blur and with <BlurEffect Radius="5" KernelType="Gaussian"/> But is there a WPF way to blur the background behind the panel, and not it's contents? The background of the StackPanel is a desktop, and the window that hosts it is set to AllowTransparency="True" to allow the custom-shaped look. What the background of the StackPanel? an

how to make the blur effect with react-native?

问题 how to make the blur effect with react-native ? like 'background-image' and i want to switch the effect 'blur' and 'none'，'none' means no blur effect 回答1: Now you can do this without any library using the prop: blurRadius . E.g <Image style={styles.img} resizeMode='cover' source={imgSrc} blurRadius={1} /> Explanation : the number(1) means the amount of blur you want to apply on the image, the higher the number, the blurrier the image. Unfortunately, this doesn't work on Android yet (RN 0.40.0

Passing Array to rsForEach in Renderscript Compute

由 不想你离开。 提交于 2019-11-28 21:36:58
问题 I found there's lacking good documentation in RenderScript, for what I know, forEach in RS is to execute the root() for each individual item in the allocation. I am trying to make a library for Renderscript that does Image processing, as a starting point, I reached this great answer. But the problem, is that the blur operation is on Each pixel and each pixel requires another loop (n with blur width) of calculation. Although running on multi-core, it is still a bit too slow. I am trying to

CSS3 / HTML 5 / PNG blur content behind element

由 蓝咒 提交于 2019-11-28 16:54:47
I'm trying to blur the content behind a fixed position header so that the content behind it has the user scrolls is blurred when behind this div. I used to achieve this with simple opacity in CSS but this does not blue the content behind the DIV, merely imposes a translucent panel in front of it. Is there a simple way even if its a cheat of achieving what I am after. Whether by using a PNG background image or in CSS. Take a look at the way iOS7 does this http://www.apple.com/ios/ios7/features/ . It's 2015 now, and Apple announced Safari 9, which supports a new CSS feature, the backdrop-filter

jQuery: On form input focus, show div. hide div on blur (with a caveat)

问题 I am able to make a hidden div show/hide when an input field is in focus/blur using the following code: $('#example').focus(function() { $('div.example').css('display','block'); }).blur(function() { $('div.example').fadeOut('medium'); }); The problem is I want div.example to continue to be visible when the user is interacting within this div. E.g. click, or highlighting the text etc. within div.example . However div.example fades out whenever the input is not in focus and the mouse is

How to prevent Android's drawBitmap from only drawing black images?

由 ╄→гoц情女王★ 提交于 2019-11-28 16:01:21
As per the original question , The end result is a rounded-rect png in an ImageView with a natural looking drop shadow. I have the shadow working, but when it draws, it makes the entire image black. How can I prevent the original image (definitely not black) from being black when adding the shadow? BlurMaskFilter blurFilter = new BlurMaskFilter(2, BlurMaskFilter.Blur.OUTER); Paint shadowPaint = new Paint(); shadowPaint.setMaskFilter(blurFilter); int[] offsetXY = new int[2]; Bitmap originalBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.pier_t); Bitmap shadowImage =

Implementing Gaussian Blur - How to calculate convolution matrix (kernel)

问题 My question is very close to this question: How do I gaussian blur an image without using any in-built gaussian functions? The answer to this question is very good, but it doesn't give an example of actually calculating a real Gaussian filter kernel. The answer gives an arbitrary kernel and shows how to apply the filter using that kernel but not how to calculate a real kernel itself. I am trying to implement a Gaussian blur in C++ or Matlab from scratch, so I need to know how to calculate the
