Adding Signatures to an Image (annotation stamp)

You can create stamp annotation programmatically or with user interaction. For creating annotation with user interaction see Adding Annotations through a User Interface.

[C++]

#include “BiAnno.h”

/* Create a new stamp as annotation object */

// lAnno is a valid annotation handle

if (CreateAnnoObj(lAnno, A_STAMP) != ANNO_UNDEF)

{

         // Set image for stamp annotation object

         // hBitmap: bitmap object

         AnnoObjSetStampBMP(lAnno, hBitmap);

         // Set the position of the annotation object

         AnnoObjSetPos(lAnno, 10, 10);

         // Set the size of the annotation object

         AnnoObjSetSize(lAnno, 50, 50);

         …

         // Refresh annotations

         …

}

[VB]

‘ Create a stamp as annotation object

If BiAnno.CreateAnnoObj(aotRect) Then

         ‘Set image for stamp annotation object

         ‘ hDib: Handle of the DIB

         BiAnno.AnnoObjSetStampDIB (hDib)

         ‘ Set the position of the annotation object

         BiAnno. AnnoObjSetPos (10, 10)

         ‘ Set the size of the annotation object

         BiAnno.AnnoObjSetSize (50, 50)

         …

         ‘ Refresh annotations

         …

End If

[C#]

/* Create a stamp as annotation object */

{

         // Set image for stamp annotation object

         // hDib: Handle of the DIB

     BiAnno.AnnoObjSetStampDIB(hDib);

     // Set the position of the annotation object

         BiAnno.AnnoObjSetPos (10, 10)
