Change Jpeg into progressive Jpeg Image [closed]

由 ♀尐吖头ヾ 提交于 2019-12-03 02:59:09
I want to convert from base line Jpeg image to progressive Jpeg image. There are 10,000 images stored in my Disk. I tried one website but it is changing one at time. http://www.imgonline.com.ua/eng/compress-image.php But I want to convert them in bulk. Is there any online tools or some programming techniques? Then, let me know. Thanks. You can do that with ImageMagick which is installed on most Linux distros and is available for OSX and Windows. Make a copy before experimenting on a small batch of images! You can do a whole directory full of JPEGs like this: mogrify -interlace plane *.jpg Or,

CSS stylesheets at top or bottom? or How to solve blank page issue?

I have been putting stylesheets on top (between <head></head> ) of html. As far as I understand this is the best practice. (e.g. http://stevesouders.com/hpws/css-bottom.php ) Anyhow, recently I have experienced different results. Instead the codes below will return blank page when test.css is slow, which means I am not experiencing progressive rendering. <!DOCTYPE html> <html> <head> <link rel="stylesheet" href="test.css" /> </head> <body> Blah.. </body> </html> Then when putting test.css at bottom, I get progressive rendering. <!DOCTYPE html> <html> <head> </head> <body> Blah.. <link rel=

Progressive JPG background image trouble in Firefox

Quick question on progressive JPG backgrounds, if anyone knows. It appears that Firefox ignores the "progressiveness" of JPEGs if they are set as CSS backgrounds and waits until the image is fully loaded until displaying. I have Chrome and IE loading the background images progressively but Firefox just pops them in at full quality. I'm seeing the proof in front of me , but finding little to no info on it online. Just unanswered forum questions here and there. Anyone know anything about this? Is it a bug Mozilla know about or what is going on? Edit: Test case provided by easwee http://sample

html5 video safari downloads full before playing

由 ♀尐吖头ヾ 提交于 2019-11-29 08:55:36
Im wondering why my mp4 html5 video is not "streaming" and instead waits till it is fully downloaded before it starts playing in safari. www.pija.se I have tried QTIndexSwapper but it says the index is in the right position. Any help appreciated. looks like the MOOV atom isn't at the beginning of the file. I used ffmpeg to just relocate that (no other encoding) and then a binary compare (using HexFiend ) and a quick test seemed to show that Safari was playing the video sooner ./ffmpeg -i top.mp4 -codec copy -movflags faststart top-fs.mp4 (caveat being that even though I cleared browser cache I

How do I implement progressive loading of content as you scroll down the page? Otherwise 1000 images would load at the same time. EpokK Use infinite scrolling directive. ngInfiniteScroll DEMO HTML <div ng-app='myApp' ng-controller='DemoController'> <div infinite-scroll='loadMore()' infinite-scroll-distance='2'> <img ng-repeat='image in images' ng-src='http://placehold.it/225x250&text={{image}}'> </div> </div> JS var myApp = angular.module('myApp', ['infinite-scroll']); myApp.controller('DemoController', function($scope) { $scope.images = [1, 2, 3, 4, 5, 6, 7, 8]; $scope.loadMore = function() {
