I have a page which allows the user to upload pictures. The problem is that my old users can't resize the image themselves. I want to allow them to upload any size of image and then when the server gets it, it will create a small copy of this picture.

I have read about the file upload control in asp.net and tried it and works great. But I want to know if I can use it for another purpose. I have a video capture control that can be used for webcam apps or anything else. It has a method called HTTPUpload where it will upload an image file to the server using the HTTP upload protocol. My question is can i use the .net FileUpload control for this? And if so, how can I pass the image file straight to the .aspx page without having to submit a button? Would the file be as a query string variable?
Arguments:
WebServer = web server address
WebPage = name of upload web page
Fields = list of 'fieldname' and 'fieldvalue' values delimited with '|'
Files = list of 'fieldname' and 'file path' values delimited with '|'
Returns TRUE if successful, or FALSE otherwise.
Example
vcx.HTTPUpload "[URL] , "upload.asp",
"field1|value1|field2|value2" ,
"file1|c:foldermypic.jpg|file2|c:foldermyvideo.avi"
Where can I find a silverlight 3 or 4 user control that contains multiple file upload and resize capability?
UPDATE:This will be used for uploading images. We'd like to resize the images prior to posting up to the server.
I have made a cms where images can be uploaded. Now I have a problem that my images need to resize (in right proportion) depending on the screensize.
View 3 RepliesIn an .aspx page with the vb.net codebehind i am using IFRAME , which would be created inside the repeater control. Since i want to resize the IFRAME based on the content within the page i have been using the resize function Obtained from here on the IFRAME onload as shown below.
<iframe id="IframeSubsectionArea" scrolling="auto" width="100%" onload="resizeIframeToFitContent(this)" runat="server">
However it is throwing the error as the method could not be found in the form. Is there any client side script variant for the onload event? May i know,What might be the reason for the error and its solution?
I found this code on another site and it works great for resizing the image and keeping the quality. What I want to do at the end is check the height of the image and if it exceeds a certain number, just change the size of the image. Not resize it but just cut off part of the bottom to be a certain size.
Code:
Dim image As System.Drawing.Image = System.Drawing.Image.FromFile(src)
Dim srcWidth As Integer = image.Width
Dim srcHeight As Integer = image.Height
Dim thumbHeight As Integer = (srcHeight / srcWidth) * thumbWidth
Dim bmp As New Drawing.Bitmap(thumbWidth, thumbHeight)
i am using file upload control for uploading images. in that iam checking the condition,if Image.Width > 250 || Image.Height > 400 then i am resizing the image. but it is giving the error "The SaveAs method is configured to require a rooted path, and the path 'ProductImages/roman_sandals.jpg' is not rooted."
ProductImages is folder where i am saving image. Can anyone find why this is giving error,my code is
string strBigServerPath = AppHardcodeValue.productImgPath;
string strFileName = "";
if (prodImg.HasFile)
{
strFileName = prodImg.PostedFile.FileName;
string uniqueNum = Convert.ToString(System.Guid.NewGuid());
string shortFileName = System.IO.Path.GetFileName(strFileName);
string Extension = System.IO.Path.GetExtension(prodImg.FileName);
string newFileName = shortFileName;
prodImg.SaveAs(Server.MapPath(strBigServerPath + newFileName));
using (System.Drawing.Image Img =
System.Drawing.Image.FromFile(Server.MapPath(strBigServerPath) + newFileName))
{
if (Img.Width > 250 || Img.Height > 400)

View 7 Repliesdisplay images in small size (thumnails) and also resize the image size (kb) so the page will quickly upload images. i dont want the user will upload 2 version of images (large and small) and i dont want also to resize the image size while uploading the images to server. I want the user will upload the original images (320x480 px) and when the users will watch the gallery they will see small images (120x180px) with small kb size that will uploads fast.
View 5 RepliesI have a working application to save an image file to my sql database (Saves as "Original_Image" in the DB TBL_ImageGallery). I have a file limit on the upload of 1 MB. This also works great and the image is being saved beautifully. I found a bit of an issue. Being i am working on a network with 2 bonded T1 connections the streaming of images to my site, when tested internally, is effortless. I am not sure that this will be the same with a generic bandwidth. I want to store the original image size into the databse (already done) but also store a smaller sized (in bytes not actual size [Width, Height]) to my database in a "ThumbNail" column. This will allow the browser to only have to pass the "Thumbnail" sized image, obviously this needs to be much smaller than the original (ex: 1MB orignal I want to save as 12KB image in the thumbnail column), to the thumbnail img control in the user's interface.
I am not sure if this is possible or if there is a need of third party controls. I am interested in doing this as either a stored procedure or in the C# code on an event fire. There may be a better / other solution to this and if that is the case I am also interested

View 2 RepliesI am trying to use jquery to resize a div containing a 100% height/width image in an asp.net page. I have some code that works fine as a simple html page. Here it is:
[code]....
Anybody know why it's not working and how to fix it?
i have an image file which is of (600* 800 size) or any size . now i need to convert them into an thubnail image size which is of size **(110*110)**
but if i reduce the size of an image i should not change the Quality of image. as once we reduce an image size the the Quality of the image is gone
is there any way without affecting the Quality of the image we can convert them into an thumbnail image[ is there any built in class for that in .net)
I am searching for a way to resize and crop images to a specific size in a fixed ratio like 16:9. So I have any image and any size and it should be resized and cropped in a ratio 16:9.
Just cropping is not very nice. I want that the image is resized more and if necessary maybe cropped. Or better: I want to reuse as much as possible from the original image but resize and crop it centered so I could use it in a fixed html div with a ration of 16:9.
We are trying to find a suitable tool that allows image manipulation (resize, merge etc.) server-side. what the state-of-the-art solution are at the moment?
