Animate the fractionComplete of UIViewPropertyAnimator for blurring the background

余生长醉 提交于 2019-12-01 04:03:50
问题 So I'm using the new UIViewPropertyAnimator and UIVisualEffectView to achieve the same thing as the Spotlight search when you scrolling down on the home screen and it blurs the background. I'm using the fractionComplete property to set the procent of how much to blur when panning a UIView. animator = UIViewPropertyAnimator(duration: 1, curve: .linear) { self.blurEffectView.effect = nil } And the amount of blurriness is changed with a value between 0.0 - 1.0. animator?.fractionComplete =

Java blur Image

荒凉一梦 提交于 2019-12-01 03:41:32
I am trying to blur the image int radius = 11; int size = radius * 2 + 1; float weight = 1.0f / (size * size); float[] data = new float[size * size]; for (int i = 0; i < data.length; i++) { data[i] = weight; } Kernel kernel = new Kernel(size, size, data); ConvolveOp op = new ConvolveOp(kernel, ConvolveOp.EDGE_NO_OP, null); //tbi is BufferedImage BufferedImage i = op.filter(tbi, null); It will blur the image but not all portion of the image. Where I am missing so that it will blur complete image. Without any path . The standard Java ConvolveOp only has the two options EDGE_ZERO_FILL and EDGE_NO

Is it possible to smooth a scaled TBitmap in Delphi?

寵の児 提交于 2019-12-01 03:08:59
问题 I am using Stretched=True on a TImage with a 256x256 bitmap. This gets scaled down by 1,2,4 or 8. As expected, text on the bitmap gets more horrible the more I depart from '1'. I notice though that Windows 7 explorer renders a scaled down version of the bitmap 'softer' and more pleasing. Is it possible to 'blur' a TBitmap in this way? 回答1: I suppose you mean Stretched = True on a TImage, not on A TBitmap. Unfortunately TImage has no resamplers built in, when it comes to resizing images in it.

jQuery blur should not fire if div is clicked/focused

假装没事ソ 提交于 2019-11-30 21:32:37
I have a standard text input that has a blur event. The blur event should fire when anything in the document is clicked (other than the input AND <div id='show-anyways'></div> ). My problem is that I don't know how to add the <div id='show-anyways'></div> to negate the blur event function. Hopefully I have explained myself well enough, I know it's kinda a weird situation. Please let me know if you need more info. charlietfl Use the event target to determine what is clicked. Following will track all clicks on document and not trigger blur() if element is the DIV or the Input. var $input=$( '#MY

gaussian blur with FFT

家住魔仙堡 提交于 2019-11-30 15:08:19
问题 im trying to implement a gaussian blur with the use of FFT and could find here the following recipe. This means that you can take the Fourier transform of the image and the filter, multiply the (complex) results, and then take the inverse Fourier transform. I've got a kernel K, a 7x7 Matrix and a Image I, a 512x512 Matrix. I do not understand how to multiply K by I. Is the only way to do that by making K as big as I (512x512) ? 回答1: Yes, you do need to make K as big as I by padding it with

Yes, you do need to make K as big as I by padding it with zeros. Also, after padding, but before you take the FFT of the kernel, you need to translate it with

How can I force ng-click to take precedence over an ng-blur event?

When I click the save button it triggers an ng-blur event, how can I make the buttons ng-click event to trigger instead? I still want the ng-blur event to trigger if I click outsida the button or input field. http://jsfiddle.net/tidelipop/wyjdT/ angular.module('MyApp', []) .filter("placeholder", function(){ return function (text, length, end) { //console.log(typeof text, text, length); if(typeof text === 'undefined' || text == ''){ text = 'Click to edit...'; } return text; }; }) .directive("inlineEdit", function($compile, $q){ return { restrict: "A", replace: true, template: function(tElement,

Android draw with blur

I need do draw on Android's Canvas using Blur effect, it is a very simple feature, I need to draw a circular area, which is blurred (the foreground) and the background transparent, I can do everything with manipulating the colour alpha to do it with custom transparency but I need it to be blurred instead of transparent.. any ideas? user2903200 (For those who are coming back, though this is an old question) On the Paint object which you are using to draw the Color, set paint.setMaskFilter(new BlurMaskFilter(8, BlurMaskFilter.Blur.NORMAL)) Then, in Android Manifest.xml, set android

Blur the background of the WPF container

隐身守侯 提交于 2019-11-30 07:27:34
问题 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
