i am using the ghostscriptsharp wrapper for c# and ghostscript. I want to generate thumbnails out of pdf-files. Further Information on the sample-code are given here.There are different Methods imported form the ghostscript-c-dll "gsdll32.dll".
[DllImport("gsdll32.dll", EntryPoint = "gsapi_new_instance")]
private static extern int CreateAPIInstance(out IntPtr pinstance,
IntPtr caller_handle);
[code]...
I have an example to convert pdf to images using GhostScript following this link:
[URL]convert pdf to images using GhostScript . So how can I do that better?
I am using GhostScript to generate some thumbnails of PDF pages in an ASP.NET application. I have it wrapped in this library called GhostScriptSharp that just uses DllImport to call methods in the GhostScript DLL.It looks like this wont work on a medium trust hosting environment, either because of the fact that it is calling unmanaged code, or that it looks like the library is creating files all over the place (outside my virtual directory). I ran Process Monitor and saw it trying to Read, QueryNameInformationFile, CreateFile and QueryStandardInformationFile in places like:
C:WINDOWSsystem32HalftoneDefault
or
C:gsgs8.63libHalftoneDefault
or
C:gsfontHalftoneDefault
Any ideas about whether this is "fixable" to run in medium trust? If I can't use GhostScript, is there another free/open source library that WILL work in Medium trust?
I have an ASP.NET Web Forms Application in migration process to ASP.NET MVC 1. Urls are as follows:
[URL]
(hxxp because stackoverflow thinks they are links and prevents me from posting so many)
"mvc" is another application inside my Web Site in IIS7.
I now need to be able to do this:
[URL]
Where 'subsiteName' can be anything and must be checked in runtime. I can't create directories for each subsiteName.
I thought of UrlRewriting, so /subsiteName/* rewrites to /*, but then I'd have to rewrite from WebForms to MVC.
I can't imagine a way to make a request to [URL]ever be taken by the MVC application in this scenario.
How to get thumbnails from video(wmv) in c#
View 1 RepliesI'm trying to get video thumbnail like facebook does.
I achived to do that for youtube videos, but i need to get to all type os video sharing websites .
I need to create a thumbnail solution in order to display pictures of products.
There can be more than 1 thumbnail per product and I need a way to enlarge the image as well. The thumbnails will be displayed in atleast 3 or 4 pages across the system and I need the ability to delete them as well. For version 2 of the software (knowing PM's it may be thrown into Version 1), I think I will need to be able to enhance this feature to allow movie clips so that's something I need to keep in mind. The images will be stored in the DB so I can sort the code to retrieve them but I'm originally a windows programmer and this is my first major ASP.NET project and also my first attempt at C#.
I have ran into an issue where I have to use ASP.NET to do a Thumbnail of images uploaded since the hosting company does not have any of the required ASP Classic 3rd party utilities that I can use. I have played around with several different Upload scripts before I found a tutorial on using: Uploadify (Love this script) with ASP.NET. [URL] What I am needing to do with the script is to create Thumbnails of the images that are uploaded, and when I try to do so, I get an IO Error. I was informed that I would have to create a Web Application instead of the Web Site as the web application would give me the default.aspx.designer.cs file for setting the FileUpload control as Public to be used in the upload.ashx file. But after doing that it basically breaks the code. What works in the Web Site, does not seem to want to work in the Web Application. What I would like from the .NET community is some help in making the Uploadify script to create Thumbnails. The script for the Thumbnails that I am using (or trying to use) is here

- In have a website where users can upload their photo and along with their profile.- I store the photo as binary data in database.- Using ASP.NET MVC 2.0 FileContent option, I display Photo back in the browser, when user view his/her profile detailsQuestion: Currently I am showing image as-is and not restricting width/height, so that users see exactly whatever image they uploaded as-is without distortion. However I want to do like every other website: Show only smaller image alwayswith fixed size and allow user to click on it to pop-up and show original image as-is in pop-up.NOTE: I can do this simply restricting width and height to fixed limits but still show original image. But in this case image is distorted as it was not originally designed for this dimension.This very basic question and I am seeing many options, including some libraries. But don't know what is best way to do this using ASP.NET MVC 2.0

View 1 RepliesWe are planning to introduce Load balancing in our server environment. Our site has lots of thumbnails (Thumbimages) to get displayed on the website.

I'm trying to create my own image viewer w/thumbnails using a datalist control. I found some ASP.Net code that utilizes another ".aspx" page to view the images. However, I wish to load the thumbnail images into a DataList control on my page and not another page. I've never done this before so I'm a little confused on the highlighted piece of code.

View 1 RepliesI have googled around for a solution and it seems that a lot of posts are dealing with these kind of things. Unfortunatley none of them seem to help me. I'm trying to resize an image dynamically to create a thumbnail. I'm basically loading a current JPEG into an image object and using the following commands to create a new image:
[Code]....
I put the image which I get from the code next to a manual re-size which was made in Photoshop. You cannot even compare between the two, the dynamic one looks so blurry when you compare it to the one made in Photoshop. Is there a way around this? I imagine Microsoft found a solution for this by now. Otherwise I will have to upload manually 4-5 different versions to every image on my website which doesn't sound right to me.
Is it possible to display thumbnails for the photos when uploading them to the server? Say, when user selects a photo on the local drive, a thumbnail is displayed on the page for preview and when user clicks on the "Upload" button, the photo will be sent to server.
