This example shows how to enumerate through a set of files creating thumbnail images from the originals.

We start by creating the variables and a list of files given a file folder.

[VBScript]
Set fso = CreateObject("Scripting.FileSystemObject")
Set fldr = fso.GetFolder(Server.MapPath("Picture Folder"))
Set canvas = CreateObject("ImageGlue6.Canvas")

Now we can enumerate through the list of files, creating thumbnails of each file.  We do this by telling ImageGlue that we want the image height to be less than or equal to 120 pixels.  If the original height of the image is less than 120 pixels, the original size of the image will be used, otherwise the width will be calculated based on a height of 120 pixels and the aspect ratio of the original image.

Also note that we could substitute the 'height<=120' parameter setting with 'width<=120' to limit the width instead of the height.

[VBScript]
For Each theFile In fldr.Files
  theFile = theFile.Path
  theName = theFile.Name
  canvas.DrawFile(theFile, "height<=120")
  canvas.SaveAs(Server.MapPath("Thumbnail Folder") & theName & ".jpg", "")
  canvas.Clear
Next

Sample output images are shown below.
