Add XMP MetaData to JPG or TIFF

Demonstrates how to add XMP metadata to a JPG or TIFF image that doesn't already have XMP metadata.

CREATE PROCEDURE ChilkatSample
AS
BEGIN
    DECLARE @hr int
    DECLARE @sTmp0 nvarchar(4000)
    DECLARE @xmp int
    EXEC @hr = sp_OACreate 'Chilkat.Xmp', @xmp OUT
    IF @hr <> 0
    BEGIN
        PRINT 'Failed to create ActiveX component'
        RETURN
    END

    DECLARE @success int

    EXEC sp_OAMethod @xmp, 'UnlockComponent', @success OUT, 'Anything for 30-day trial.'
    IF @success <> 1
      BEGIN
        EXEC sp_OAGetProperty @xmp, 'LastErrorText', @sTmp0 OUT
        PRINT @sTmp0
        RETURN
      END

    DECLARE @xml int

    --  The first step is to create a new XMP document, which is nothing
    --  more than XML.  The NewXmp method returns an XML document with
    --  the standard XMP boilerplate.
    EXEC sp_OAMethod @xmp, 'NewXmp', @xml OUT

    --  Add some properties...
    EXEC sp_OAMethod @xmp, 'AddSimpleStr', @success OUT, @xml, 'Iptc4xmpCore:Chilkat', 'Blah blah'
    --  If you wish to view the XML, save it to a file and review it
    --  with a text editor:
    EXEC sp_OAMethod @xml, 'SaveXml', @success OUT, 'newXmp.xml'
    IF @success <> 1
      BEGIN
        EXEC sp_OAGetProperty @xml, 'LastErrorText', @sTmp0 OUT
        PRINT @sTmp0
        RETURN
      END

    --  To add the XMP to the JPG (or TIFF), simply load the JPG,
    --  append the XMP, and save:
    EXEC sp_OAMethod @xmp, 'LoadAppFile', @success OUT, 'scream.jpg'
    IF @success <> 1
