Office web components are great components to work with charts and another images. The previous live sample, captcha asp project generates text for human-testing forms, preventing automated submitions.

Simple ASP image resize function

This sample uses Chart object from OWC library to resize any image and convert the image to a specified format (.jpg, .png, .bmp, .gif...). The image is placed to the chart using SetTextured property, which can load any image file from a disk. Then you can use border property to set some frame around the image (or left the frame blank) and export the picture using ExportPicture method to a disk or get the picture as a binary data for BinaryWrite using GetPicture method.
You can see this short code with Huge ASP file upload live at Upload with resize page.

Upload and image resize sample

Image to resize:

Next piece of VBScript code if from the live resize sample and demonstrates the ResizeImage function. The source gif, jpeg or png image from upload is saved to a temp folder. The code reads data for the resize - new width and height and out format and then calls response.binarywrite ResizeImage().

'Set timeout to 30 minutes
Server.ScriptTimeout = 1800

'Set an upload limit to 5MB
Form.SizeLimit = 5*&H100000

'Set the destination path - Path to store uploaded files.
Dim DestinationPath: DestinationPath = Form.WindowsTemp & "\upload\"

Const fsCompletted  = 0

If Form.State = fsCompletted and len(Form("Image").FileName) >0 Then 'Completted
  'was the Form successfully received?
  
    Form("Image").Save DestinationPath
    
    Dim TempFileName, OutFormat, Width, Height
    TempFileName = DestinationPath & Form("Image").FileName
    OutFormat = Form("OutFormat")
    Width = clng(Form("Width"))
    if Width>8000 then Width = 8000
    Height = clng(Form("Height"))
    if Height>8000 then Height = 8000
    
    'Export the picture from the ASP script
    response.ContentType = "image/" & OutFormat
    response.binarywrite ResizeImage(TempFileName, OutFormat, Width, Height)

createobject("Scripting.FileSystemObject").DeleteFile TempFileName 
    response.end
ElseIf Form.State > 10 then
  Const fsSizeLimit = &HD
  Select case Form.State
    case fsSizeLimit: response.write  ".."
    case else response.write ".."
  end Select
End If'Form.State = 0 then
