image-resizing

问题 I have a form in my site that allows the user to upload a photo. My android app uses WebView to allow users access the site. On click of the upload button the app allows the user to choose between an image already existing in the gallery or take a new photo and upload that image. The code I have used for this is showAttachmentDialog is called by the openFileChooser private void showAttachmentDialog(ValueCallback<Uri> uploadMsg) { this.mUploadMessage = uploadMsg; File imageStorageDir = new

问题 I want to create a drag and drop interface in my Universal Windows App. Users will be able to drag and drop images from a ListView (or similar) to a Canvas where they can resize and move the images. I have found how to move the images, but now I can't seem to find a way to accept multitouch, find the appropriate image to resize, and resize the image itself. Is there a simple way to do this? 回答1: This is what I eventually went with: using Windows.UI.Xaml; using Windows.UI.Xaml.Controls; using

问题 I am currently using a php gd implementation to resize images which constantly runs out of memory - rather quickly. I guess the problem are the php functions, like imagecreatefromstring etc. Is there an easy implementation to resizing images which doesn't use this functions, so I won't have to increase my php.ini memory limit? 回答1: GD don't use that much memory, so you have other problems in your code. If you resize multiple images and don't call imagedestroy on a newly created image, you run

问题 I successfully applied the Universal Image Loader library (1.8.3 version) to my app, and I'm trying to resize the image before displaying it in the gridview item (because sometime image is too big to cache it in memory.) Here is what I am trying: ... BitmapFactory.Options resizeOptions = new BitmapFactory.Options(); resizeOptions.inSampleSize = 3; // decrease size 3 times resizeOptions.inScaled = true; options = new DisplayImageOptions.Builder() .showStubImage(R.drawable.blank)

问题 I've got a little problem here. I've been trying to do an image gallery with JavaScript but there's something that I got a problem with. I can get the image to resize when the first image load, but as soon as I load another image, it won't resize anymore! Since the user will be able to upload a lot of different size pictures, I really need to make it work. I've checked for ready-to-use image gallery and such and nothing was doing what I need to do. Here's my javascript: function

问题 I have an already developed a Laravel web app. I've just discovered that whenever I upload an image taken from a mobile phone it rotates and if the image px is bigger than the containers then the image is cut partially as I have kept overflow as hidden. I have heard of the image intervention package but i don't know how to apply it to my app, if there is any other way to resolve then issue without any additional package then that would be of great help. profile-avatar{ width: 420px; height

问题 I have a background image in a header that automatically resizes to the width of the window. However, the height does not adjust properly -- an inherited CSS property sets the div to a fixed height of 50px. Currently, I'm using: background-size: cover; I can specify a fixed height for the div that will be observed, but then the background is only correct at a specific window size. If I set the size to auto or 100%, it goes to 50px; How can I make it ignore the height it thinks it should be

问题 I had the resize.php script working on my previous server/domain and when you go to it HERE you can see the division by zero error. BUT! if you go to the same script on the new domain/server HEREits a blank page with no errors which leads me to believe something is not happening like it should be. I'm a quick learner but a bit of a PHP noob. Any advice with simply resizing a php array of images and displaying them I would appreciate any help. <?php session_start();header("Pragma: public")
