I am using a panel whose background image is set. Though I dont want the background image to get tiled but it should stretch inside the panel. How much ever small the image is, it should get stretched and fit to panel according to the size of panel.How do I get this functionality??Please note that there is a specific reason that I want to stretch the panel background image and I cannot use any <img> tag.
View 1 Replies In trying to upload images to a server, I often get the following error "Maximum request length exceeded.".
I have tried to check for the size in codebehind but it appears that the error comes from the service provider or something else because I never even get to debug it since the error appears even before the Page_Init Subroutine in codebehind.
What is the best method of checking for the image size and then resizing it dymamically to a maximum file size as well as length and width size.
I am developing an ASP.NET 3.5 web application in which I am allowing my users to upload either jpeg,gif,bmp or png images. If the uploaded image dimensions are greater then 103 x 32 the I want to resize the uploaded image to 103 x 32. I have read some blog posts and articles, and have also tried some of the code samples but nothing seems to work right.
View 4 RepliesI have a photo on my server image1.jpg in high resolution, and I need it to be resized everytime it is send to client depending with dimension I put but should not make extra file on disk.
I used aspjpeg for this in past but now I need something that can be used on servers that do not have aspjpeg instaled.
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.

what should i do ?
I have uploaded a .jpg image and resized as Small and Large thumbnail. The small image is (135 X 173) but after resizing the small thumbnail image file size is of 40.8 KB. And mostly all images (around 64) thumbnails having file size more than 40 KB. Due to which thumbnails taking lot of time to get display.
Is there a way through which we can reduce the image file size upto 8 to 12 kb, but without effecting image quaity??
Below is the source code that i am using for resizing an image:
If FileUpload1.HasFile Then
Dim stream As Stream = FileUpload1.PostedFile.InputStream
Dim x As String = IO.Path.GetExtension(FileUpload1.FileName).ToLower
If x = ".jpg" Or x = ".jpeg" Then
Dim image As New Bitmap(stream)
[Code] .....
I found some code that resizes an uploaded image ( stream ) to a pre-determined size. Using this code, it works perfectly..
Code:
' make sure we have a file .
If FileUpload3.HasFile Then
Dim name As String = FileUpload3.PostedFile.FileName
Dim Justname As String = Path.GetFileName(name)
Dim length As Integer = FileUpload3.PostedFile.ContentLength
[Code] ....
What I'd like to do is move this code into a Class so I can call it from other pages, so I created a class and added this code...
Code:
Imports Microsoft.VisualBasic
Imports System.IO
Imports System
Imports System.Xml
Imports System.Xml.Xsl
[Code] ....
As you can see, I'm trying to pass in a stream and defined width, and I want it to pass back the image ( if the size if greater than what I expected.
I'm trying to call the class like so.
Code:
' make sure we have a file and that we have an ID to set it to.
If FileUpload3.HasFile Then
Dim name As String = FileUpload3.PostedFile.FileName
Dim Justname As String = Path.GetFileName(name)
Dim length As Integer = FileUpload3.PostedFile.ContentLength
[Code] ....
Don't worry about the cc.imgStr this is just the path to my class which is defined futher up.
The Error I get is "Value of type system.io.stream, cannot be converted to ' 1 dimensional array of byte' "...
I have a script which resizes images, I did not write this script, nor do I know any ASP.NET, but I have been assigned the task of fixing an issue with it!
The problem is, the resulting image from the resize appears to be of less quality than the upload, even if the file uploaded is already set to the correct size.
Uploaded image - [URL]
Resized image - [URL]
The script that is doing the resizing is as follows, how to correct the issue?

View 7 RepliesI'm using JCrop, by using Mikes great article at: http://www.mikesdotnetting.com/Article/95/Upload-and-Crop-Images-with-jQuery-JCrop-and-ASP.NET
There are two things I haven't been able to figure out how to do though:
(1) How do I check if the uploaded image is big enough? (i.e. how do I determine width of image is > 200px")
(2) How do I resize the cropped image to 200px in width.
I have ASP.NET form with an upload control for users to post an image. On the server I load that image (using the Bitmap class) and resize it. Is there any danger in doing that when users upload malicious or affected files or will the code just throw an exception at some point and stop the whole process?

I'm doing a postback to generate a chart. When the user clicks the button it is using jQuery to add some html to the page to show an animated gif and an overlay.
This works fine in IE and FF but in Chrome the image doesn't load. Anybody know what's going on here?
While looking into the problem I noticed that if I run this code in the JavaScript console it works, and it will work as expected after running it in the console (displays image on postback).
Here is the code I'm using to add the html:
$("body")
.append("<div class='ui-widget-overlay working'></div>")
.append("<div class='ProcessMessage working'><img alt='Loading' src='images/indicator_big.gif' /><br /><br />Loading...</div>");
