Hi all,

I have written a little piece of code that uploads an image and resizes it before saving it to a database. The problem i have is with the file size of the resized image.

EG. Using a picture with dimensions of 800 x 600 and a file size of 70kb, I upload and resize to 400 x 300, the file size of the resized image however is 300kb, which is ridiculous and completely unacceptable.

If anyone could help with why the image file size becomes so large I would be greatful.

Thanks.

What code do you use to resize? That would help. Are you switching picture formats or changing the resolution?

Hi all,

Incase it is of any use, here is the code I use to resize and save the image:

Dim aFile As HttpPostedFile = Me.myFile.PostedFile

Dim fileName As String = Path.GetFileName(aFile.FileName)

Dim imgStream As Stream = aFile.InputStream()

Dim img_New As System.Drawing.Image = System.Drawing.Image.FromStream(imgStream)

Dim imgOutput As New System.Drawing.Bitmap(img_New,800,600)

imgOutput.Save(Server.MapPath(".") & fileName)


As I said, using this method seems to increase the file size.

Any help is appreciated.

Thanks

Hey,

Is it saving as a bitmap, instead of a gif or jpeg? I guess that from the System.Drawing.Bitmap class. If so, bitmaps are always going to be gigantic. See if you can go to a gif or jpeg.
