问题 I am working on one project I want to display the pdf which is on the website, I have the url of the pdf any idea how I can do it. Also I want to create a thumbnail of the pdf which is on the website. 回答1: you could display a pdf in your device. Passing the url to UIWebView directly.

问题 I'm trying to use this thumbnail generator, but as you can see you have to go through this link to create an image thumb. This is maybe a dumb question, but how do I get it work inside a php script that saves some variables to database?

I bet there's really easy solution but I can't find it. 回答1: I really can't see your problem... Do you want

I'll try to demonstrate that confusing sentence with some nice ASCII :} LANDSCAPE EXAMPLE: XXXXXXXXXXXXXXXX XXXXOOOOOOOOXXXX XXXXOOOOOOOOXXXX XXXXOOOOOOOOXXXX XXXXOOOOOOOOXXXX XXXXXXXXXXXXXXXX XXXXXXXX XXXXXXXX

问题 For simplicity lets say that I have a web page that needs to display thumbnails of images. The images locations are stored in a database(the images are stored on Amazon S3). Is it possible to have my web server scale down the large image before it is delivered to the client? This way I don't have to store thumbnails of every image and the client can download a smaller file. 回答1: Sure, no problem. There's plenty of resources on the web that show how to dish up an image from a database. So I

问题 I'm having a heck of a time with creating thumbnails and then converting them into a byte array. I've tried three methods, and all 3 times I get an error. The first was using Bitmap.GetThumbnailImage, which I have used in the past and then saved directly into Response.OutputStream The second was using System.Drawing.Graphics with DrawImage().

问题 For the popular video player, like sl2videoplayer, http://www.codeplex.com/sl2videoplayer, my question is how is the thumbnail image of Siverlight video is displayed before we click play (in the scenario of non-autoplay). thanks in advance, George 回答1: the MediaElement that the Video Player uses will show a thumbnail image of the frame at the current position. Otherwise, tools like Expression Encoder create thumbnail images (JPEGs or PNGs) that will be used for the video thumbnails and

Here is the link to the php class: http://www.darrenhoyt.com/2008/04/02/timthumb-php-script-released/ 回答1: I wrote this up just for you :) ...

问题 The server hosting my website doesn't have ffmpeg and I am not allowed to install any additional extensions. Is there any other way I can make video thumbnails dynamically? Perhaps some kind of web service, where I pass the video file and as a result I get a picture file.
