blur

问题 Here is what's bothering me. Let's say I have a picture of a car. I would like to put that picture in a canvas, blur it and then save the blurred image. Is it possible? The image doesn't necessarily have to be in a canvas if there is another way to blur and save it. I've tried using blur.js , pixastic.js , and foggy.js and all of them add the blur effect to the image but it stops there, I can't save it. I can right-click on the image but there is no " save image as " link. Thank you in

问题 I have a simple form that I want to validate using blur if the text field is empty. The below code should work, but keeps alerting me even if I pop in some text, please, what am I doing wrong? var name = $("input#name").val(); $("input#name").blur(function() { if (('input#name:empty')) { // Testing alert('Empty'); } }); 回答1: You want to use $(this).val(), like this: $("input#name").blur(function() { if ($(this).val().length === 0) { // Testing alert('Empty'); } }); Currently you're checking

问题 I am using Perl and ImageMagick (Perl-API). In a first step i take a rectangle of an image and blur this part of the image (plus rotation of that rectangle).

Now my aim is to blur the rectangle of that image with the result of bigger pixels. How can i achieve that? Here the code of Mark Setchell that i use so far: #!/usr/bin/perl use strict; use

问题 Not sure what causes this? If I user slideDown in Firefox the text rendering cuts off the top of the letters before the animation is complete. This is ok in IE. If I then change the animation to use fadeIn instead, the blur does not happen in Firefox but the text is very jagged in IE. From another question I have asked in the past pertaining to animation, the guy told me that I should wrap that which I want to animate in another DIV and animate that instead. This sorted out the jerkiness

问题 I'm writing up custom code for a CMS for a website. When a user clicks on the submit button (created with jQuery UI), it calls the click event on the button, which in turn calls a submit event, which submits the form. Said form also checks specific fields to see if they have text, and will show error messages and deactivate the submit button until the issues are resolved. To do this, I currently use .focus(), which has a .blur() function inside it which checks to see if the error was fixed

问题 Like the title says: I want to blur and darken a downloaded image. The BlurMaskFilter in the SDK sounds relevant, but I can't find any documentation on it. Any suggestions? 回答1: I've only used this once and just for fun (not an expert). Try something like: paint.setMaskFilter(new BlurMaskFilter(20, Blur.OUTER)); for more there is a nice blog here. 来源： https://stackoverflow.com/questions/6064523/how-can-i-blur-and-dim-an-image-to-be-used-as-an-activity-background

问题 I've worked on a fiddle to show the simple validation that I'm trying to do for my user ID field: Make it required (validate as aggressively as possible) Set a minimum length (validate as aggressively as possible) Set a maximum length (validate as aggressively as possible) Run an AJAX call to ensure user ID doesn't already exist ( I want to only run this on blur ) I'm not using the validate() - remote rule because I wanted to have a custom object returned instead of just a simple string.
