Introduction
WPF AnnStampObject
Note: This topic is for Document/Medical only. The stamp annotation object (AnnStampObject) can be a bitmap image or a text string in a rectangular frame. With the automated functions, the user clicks and drags to specify a rectangle. Then, if the user specifies a text string, the text is centered in the rectangle. If the user specifies a bitmap, the bitmap is scaled to fit the rectangle. On a device that displays 256 colors or less, you should use a fixed palette when displaying bitmaps. Otherwise, a palette shift will occur on stamp objects containing bitmaps. Programmatically, the boundaries and location of the stamp object can be controlled using the following properties:
