Resize Images

Hi REA_ANDREW,

Following will help you.

True Image Resizing

Also, you must modify this line, if you want to let the width be variable without limits:

Dim bmp As Bitmap = CreateThumbnail(Path, Size, Size)

replace it with:

Dim bmp As Bitmap = CreateThumbnail(Path, Size, sSize)


To give u an example of this, use the code below also:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
        Dim rLink = Request.QueryString("vLink")
        Dim rWidth = Request.QueryString("w")
        Dim rHeight = Request.QueryString("h")

        Dim sSize As String = rWidth
        Dim Size As Integer = rHeight


===========================================

Now change the image tag to:

<img src="sizer.aspx?vLink=http://www.myDomain.com/img/myImage.jpg&w=500&h=300">

This will resize the image to 500 by 300.

this link  has sample project what you want

Thanks

Andrew,

You need to include the following lines at the very top:

Imports System.Drawing.Imaging
Imports System.Net
Imports System.IO

ok I have narrowed the rrors down to 2

Error      1      Type 'ImageFormat' is not defined.      C:\Inetpub\wwwroot\frag\sizer.aspx.vb      50      29      C:\...\frag\
Error      2      Name 'ImageFormat' is not declared.      C:\Inetpub\wwwroot\frag\sizer.aspx.vb      117      41      C:\...\frag\


I am designing with ASP.NET 2.0

I have.  but in asp.net 2.0 the first one is now

Imports System.Drawing

I fixed it using this at the top

Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Net
Imports System.IO

Yes, I just looked it up and saw that the namespaces had slightly been changed, so you had to include Drawing as well.

All the best.
