Using A Tiff Image On A Webpage?
Oct 7, 2010I may be forced into using a tiff image on a webpage.
Do most modern browsers handle tiffs. Are there any gotchas?

Tiff - How To Display Image That Is Located On Another Server On The Network
Apr 13, 2010I've got a ASP.NET site that's located on a local server (MY_SERVER). And one of the things it does is pull up tiff files which are located on another server (ANOTHER_SERVER). The location of each of these files is stored in SQL. I pull up each of these images and am supposed to display them. The problem is:
the files are not named with a tiff extension (does it matter?) they aren't displaying at all.
I am using an Image control to display these images, and I'm not sure if it matters that the extension is not set (does the image control know the difference between an jpg and a tiff without the extension?)
I am guessing the images aren't displaying because they are not on the same server MY_SERVER that the images are located (ANOTHER_SERVER).
edit: actually displaying the tiff files were amazingly simple:
protected void Page_Load(object sender, EventArgs e)
Response.ContentType = "image/png";
new Bitmap(Request.QueryString["ImagePath"]).Save(Response.OutputStream, ImageFormat.Gif);
}
but because the images are located on ANOTHER_SERVER I still can't access them. I may just do a hack where I copy them to a local directory on MY_SERVER but there's gotta be a simple way to fix this. Anyone?
Setting ContentType = "image/tiff" And Sending An Image Is Not Working In IE?
Jan 20, 2011I need to send an image (as a downloadable file) from an ASP web page. It is working correctly in every browser except for IE (all versions).
Here is the server side code:
bool export = Request.QueryString["Export"] != null;
if (export)
{
byte[] allBytes = File.ReadAllBytes(@"C:MyImage.tif");
Response.ContentType = "image/tiff";
Response.AddHeader("content-disposition", "attachment; filename="MyImage.tif"");
Response.OutputStream.Write(allBytes, 0, allBytes.Length);
Response.OutputStream.Flush();
Response.End();
return;
}
And here is the JavaScript:
$('#ExportFrame').attr('src', 'Default.aspx?Export=true'); // ExportFrame is an iframe
In IE, I keep getting an error saying "Internet Explorer cannot download Default.aspx from localhost". I thought it might be an issue with loading it in an iframe element, but redirecting to the URL is not working either. The really odd thing is that going to the URL (/Default.aspx?Export=true) does not work the first time, but works every time after that. Again, this works in every browser I've tried except IE.
Update:
The aspx page has the following code to keep the page from getting cached:
// Never cache this page
Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "no-cache");
Response.Expires = -1;
Removing the first 2 lines and leaving only Response.Expires = -1 resolved the issue.

C# - How To Detect If A File Is PDF Or TIFF
Apr 28, 2010I've been thrown into the middle of this project without knowing all the background. If you've got WTF questions, trust me, I have them too.
Here is the scenario: I've got a bunch of files residing on an IIS server. They have no file extension on them. Just naked files with names like "asda-2342-sd3rs-asd24-ut57" and so on. Nothing intuitive.
The problem is I need to serve up files on an ASP.NET (2.0) page and display the tiff files as tiff and the PDF files as PDF. Unfortunately I don't know which is which and I need to be able to display them appropriately in their respective formats.
For example, lets say that there are 2 files I need to display, one is tiff and one is PDF. The page should show up with a tiff image, and perhaps a link that would open up the PDF in a new tab/window.
The problem:
As these files are all extension-less I had to force IIS to just serve everything up as TIFF. But if I do this, the PDF files won't display. I could change IIS to force the MIME type to be PDF for unknown file extensions but I'd have the reverse problem.

Is this problem easier than I think or is it as nasty as I am expecting?

Web Forms :: Displaying An Image On A Webpage?
Jun 14, 2010I can do the above by placing the relevant .jpg into the VWD project.
However, I would like to be able to to do this without adding the image file to the project.
e.g. In code, get the image from C:/images/NameOfImage.jpg
The reason I am trying to do this is the website will allow the user to upload as many images as they like. Each one's details will be stored in a database, including details of which location they have uploaded the image to. On retrieval, I will get the location of a specific image from the database, and display it on the page.

Web Forms :: Can Uploaded Tiff File Be Converted To Jpeg Before Saving To Disk?
May 10, 2010My website provides a facility to upload images, using the ASP.NET FileUpload control. We accept both jpeg and tiff formats but I have just decided that all tiffs should be converted to jpegs at the time of upload. If possible, I want to avoid saving the original tiff to disk. I would any sample coding for achieving this conversion prior to saving (ideally in VB.NET, though I could always run C# code through a converter).

Web Forms :: How To Display The Uploaded Image On The Webpage
Aug 22, 2010Does anyone know how to display the uploaded image onto the webpage after the image has been uploaded via the asyncfileupload control?
I tried setting the value of an imageurl property of an image control within the OnUploadComplete event however it seems the code 1st refreshes the page, runs through the Page_Load event, then finally the OnUploadComplete, so I'm assuming since it's run last, this is why it doesn't display the imageurl.

My question is how to assign "stream" variable to Image control?

Web Forms :: Setting Webpage / Master Page Background Image?
Aug 24, 2010I want to have the background of my masterpage (the master page for all of my .aspx pages) have a sort of gradient. I imagine the only way I can do that is with an image. Or maybe even some other design, but I want to move away from the "solid color" background.
Is the easiest way to do this just to make an image and set that as the background? What image size should I make it, because some users could possibly have the normal aspect ratio, or maybe a widescreen? What should I make it like so that it looks good on [b]all[/b] computers?
