Hi,

Here a sample. let me know if you need more info.

Code: Select all

        Dim oGdPictureImaging As New GdPictureImaging
        Dim oAnnotationManager As New AnnotationManager

        Dim ImageID As Integer = oGdPictureImaging.CreateGdPictureImageFromFile("c:\test.jpg")
        oAnnotationManager.InitFromGdPictureImage(ImageID)
        Dim rectAnnot As AnnotationRectangle = oAnnotationManager.AddRectangleAnnot(Color.Red, Color.Transparent, 1, 1, 3, 3)

        'todo: change annot property here, if any
        '
        'oAnnotationManager.BurnAnnotationsToPage(True) 'Uncomment to burn annots to page
        oAnnotationManager.Close()
        oGdPictureImaging.SaveAsJPEG(ImageID, "c:\testout.jpg")
        oGdPictureImaging.ReleaseGdPictureImage(ImageID)

I did mis something when I want to display it on the screen see: "GdViewer1...." I got the image without the annotation

Code: Select all

       
        Dim oGdPictureImaging As New GdPictureImaging
        Dim oAnnotationManager As New AnnotationManager

        Dim ImageID As Integer = oGdPictureImaging.CreateGdPictureImageFromFile("c:\test.jpg")
        oAnnotationManager.InitFromGdPictureImage(ImageID)
        Dim rectAnnot As AnnotationRectangle = oAnnotationManager.AddRectangleAnnot(Color.Red, Color.Transparent, 1, 1, 3, 3)
   
        GdViewer1.DisplayFromGdPictureImage(ImageId) 

        'todo: change annot property here, if any
        '
        'oAnnotationManager.BurnAnnotationsToPage(True) 'Uncomment to burn annots to page
        oAnnotationManager.Close()
        oGdPictureImaging.SaveAsJPEG(ImageID, "c:\testout.jpg")
        oGdPictureImaging.ReleaseGdPictureImage(ImageID)

You have to call

Code: Select all

oAnnotationManager.Close();/* or oAnnotationManager.SaveAnnotationsToPage();*/

Before

Code: Select all

GdViewer1.DisplayFromGdPictureImage();

Kind regards,
