thumbnails

问题 I'm trying to get the thumnail paths , not the bitmaps objects. When I query for these, some of the thumbnail paths are null for some reason. (I have 1028 thumbnail images in my device, the cursor length is indeed 1028, but still returning nulls) I know there are 1028 thumbnail images because I checked. Here's my code: String[] projection = {MediaStore.Images.Thumbnails._ID}; // Create the cursor pointing to the SDCard cursor = this.getContentResolver().query( MediaStore.Images.Thumbnails

问题 I am trying to load local images as thumbnails as explained here. My code is below. This works fine for small images. However, when you try load larger images (e.g. 4mb) there is a huge lag. Is there any way to optimize this? Thanks Html <input type="file" id="files" name="files[]" multiple /> <output id="list"></output> Javascript <script> function handleFileSelect(evt) { var files = evt.target.files; // FileList object // Loop through the FileList and render image files as thumbnails. for

问题 Original Question (see Update below) I have a WinForms program that needs a decent scrollable icon control with large icons (128x128 or larger thumbnails, really) that can be clicked to hilight or double clicked to perform some action. Preferably there would be minimal wasted space (short filename captions might be needed below each icon; if the filename is too long I can add an ellipsis). (source: updike.org) I tried using a ListView with LargeIcon (default .View) and the results are

问题 I'm looking for a Java library that will can take a PDF and create a thumbnail image (PNG) from the first page. I've already looked at JPedal, but its insane licensing fee is completely prohibitive. I am using iText to manipulate PDF files at the moment, but I believe it doesn't do thumbnail generation. I can use something like Ghostscript on the command line, but I'm hoping to keep my project all-Java if possible. 回答1: PDF Renderer is a LGPL licensed pure-java library that makes this as

问题 I use easy_thumbnails and it works fine on a development machine but in production I get errors like shown below, when I use {% thumbnail photo.image 300x170 %} templatetag. Though can directly browse http://sitename.com/media/uploads/2012/09/13/microsoft1.jpeg`.

问题 How can I set this code to return images in 1:1 (square)? The purpose is to create a square (non stretched) thumbnail. I've tried making changes in the 'if section'.

I want it to be cropped. define('THUMBNAIL_IMAGE_MAX_WIDTH', 150); define('THUMBNAIL_IMAGE_MAX_HEIGHT', 150); $source_image_path = {here the source filename}; $thumbnail_image_path = {here de thumb filename}; list($source_image_width, $source_image_height, $source_image_type) = getimagesize(

问题 I would like all images dropped in a directory to be copied into a separate directory as thumbnails that i can then view on my site. Right now i'm researching phpthumb, but have also downloaded wideimage and zen photo. Thanks if you can find an exact duplicate to this, near matches may also be helpful.
