Web Forms :: Without Effecting Quality Reduce Image File Size While Resizing Saving To Folder
Aug 31, 2013
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)
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?
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.
I have many image in my page my images size are between 100 -200kb I want redeuce my images size to 4-5Kb ... How I can do it? is there any control to do it?
I have stored images in folder each images is more than 700kb so datalist binding process became slow.so it is possible that while loading record and corresponding images from folders Can I reduce the image size or compress images so that record fetching become faster.In database i m stroing image path and image is stored in directory.
I am uploading images in c# windows application. I am uploading the images folder wise. In one folder there are 200 to 3000 images. My one images size is about 3.10 MB to 6.2 MB. Its dimensions are 3008 x 1960, 1960 , 4000 x 2600. 6000 x 4000 . while uploading i am reducing the size of image to 400 x 266 or 266 x 400 depending on the height and width of image. but still my image size is about 227 KB. Now i want to reduce the image resolution to decrease the image size.
I am using a sql server 2008 database and I am uploading images to the server using an asp.net webapplication. I have an image column that I use to store the images. I have chosen the database to store the image and not a folder on the server, because the database table will contain only very few rows. maybe close to 10 or 15 rows.
My question is, Do I have to reduce the size (dimensions and quality affecting size on disc in kbs) of the image in code behind before uploading it to the database or do I keep it as is. The total upload size permitted is 200kb. I am thinking that when the image size (size in kbs) is small my webapplication performance will not be affected when displaying them from the database.
I am using asyncfileupload ajax control and can successfully upload and save picture on server.I need to do the following and not sure how:When user is in process of uploading, I only want them to see *.jpg *.gif and *.bmp files Once the user uploads their picture, how do I reduce the quality of the picture so it is less than 10 KB?

I need to take an uploaded image, resize it, and save it to the database. Simple enough, except I don't have access to save any temp files to the server. I'm taking the image, resizing it as a Bitmap, and need to save it to a database field as the original image type (JPG for example). How can I get the FileBytes() like this, so I can save it to the database?Before I was using ImageUpload.FileBytes() but now that I'm resizing I'm dealing with Images and Bitmaps instead of FileUploads and can't seem find anything that will give me the bytes.
In my web application, I have used AJAX Toolkit and my .net version is 3.5. When I run the application and save the page, so many ScriptResource.axd and WebResource.axd generate which makes the file size 200 to 300 KB more big. After doing the same procedures mentioned in the above link, it was working fine as all ScriptResource.axd and WebResource.axd file is removed.
But when I go from one page to another page using on click, then Object Expected Error comes and when I debug it,I found one ScriptResource.axd file containing query string like .axd?d=-bA.like this and Request. GetResponse cannot find the file and it gives 404 errror (File Not Found).
