Update a String Property in XMP

See more XMP Examples

Demonstrates how to open a JPG or TIF image file, access the XMP metadata, and update the value of a string property. (If the string property does not already exist, it is created.) VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

set xmp = CreateObject("Chilkat.Xmp")

' Load a JPG or TIF image file.
success = xmp.LoadAppFile("qa_data/xmp/AJ_123642_1511.tif")
If (success <> 1) Then
    outFile.WriteLine(xmp.LastErrorText)
    WScript.Quit
End If

outFile.WriteLine("Num embedded XMP docs: " & xmp.NumEmbedded)

' This example assumes that XMP metadata is already present in the image file.
If (xmp.NumEmbedded = 0) Then
    outFile.WriteLine("No XMP metadata already exists..")
    WScript.Quit

' Get the XMP metadata.
