image-size

问题 I read some of those website links that explain about exporting different image sizes for iOS device. But I don't really understand of those explaining. (May be I am not good at in English language.) I found these dimension for launch screen. Please let me clarify my understanding to you guys. So, when I create an image, I must create a larger size(@3x) firstly and should export that image into smaller sizes (@2x, @1x). Am I right? For example, I create 1242x2208px (3x) image and scale to 2x

问题 I was compiling a custom kernel, and I wanted to test the size of the image file.

问题 wordpress has a good support for images in general. to get new image sizes, one would just add some functions like : add_theme_support( 'post-thumbnails' ); //thumnails set_post_thumbnail_size( 200, 120, true ); // Normal post thumbnails add_image_size( 'single-post-thumbnail', 400, 300,False ); // single-post-test add_image_size( 'tooltip', 100, 100, true ); // Tooltips thumbnail size /// and so on and so on my question is : How can someone make those functions act in a dynamic manner ,

问题 I am building a webapp game that has a scrolling background. The background is just a really tall image that is copied to the smaller canvas in slices to give the sensation of movement. The image file I started with was 6000px tall (my canvas is 640px tall). All desktop browsers and iPad2 (iOS 6) loaded the image file fine and the animation looks great. However, on iPhone 4S (iOS 5) - the background never loads at all! I solved the problem by just cutting the big background image down until

问题 This is my HTML: <ul class="nav nav-pills nav-stacked custom-nav-pills"> <li><a href="#"><span class="glyphicon glyphicon-home"></span> Home</a></li> <li><a href="#"><span class="glyphicon glyphicon-user"></span> About</a></li> </ul> Now, the glyphicons which Bootstrap 3 uses are a certain size.

问题 I am optimizing my site for these higher resolution monitors (especially the new iPad). I have the site formatted the way I want, and I was just increasing the resolution of each image but still constraining it to the DIVs that I currently have. For example, I have an image with a resolution of 483x246 and I have it fitting a DIV with a set size of 188x96. The images look great on Chrome, Firefox, and most importantly on the new iPad. Even zoomed in it's nice and crisp (as opposed to my old

问题 I need to display the image size in kilobyte and the dimension (height, width) using javascript/jquery. I came across few similar posts, but none could help me. I have two set of codes, that work separately. I can't figure out how to put them together. This is the html code: <span id="preview"></span> <input type="file" id="file" onchange="displayPreview(this.files);"/> This piece of code checks for file size & previews the image: function onFileLoad(e) { $('#preview').append('<img src="'+e
