The stamp annotation object (ANNOBJECT_STAMP) can be a bitmap image, a metafile, or a text string in a rectangular frame. Only one of these three can be displayed at any time©setting the object to one of these destroys any settings for the other two. Initially, the ANNOBJECT_STAMP displays text. 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.
For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
With low-level functions, you must specify the defining rectangle. Other applicable properties have the following defaults, which you can change:
Visible |
Defaults to FALSE. It can be changed using the L_AnnSetVisible function. |
Selected |
Defaults to FALSE. It can be changed using the L_AnnSetSelected function. |
Name |
Defaults to an empty string. It can be changed using the L_AnnSetNameOptions function. |
Line width |
Defaults to 0.75 points. It can be changed using the L_AnnSetLineWidth function. (Note that when displayed, the line must have a minimum width of 1 pixel.) |
Line style |
Defaults to solid. It can be changed using the L_AnnSetLineStyle function. |

Defaults to ANNROP2_COPY. It can be changed using the L_AnnSetROP2 function. |
Fill pattern |
Defaults to solid. It can be changed using the L_AnnSetFillPattern function. |
Fill mode |
Defaults to transparent. It can be changed using the L_AnnSetFillMode function. Before calling this function enable the alpha background fill mode by calling the L_AnnSetOptions function. |

Text Border* |
Defaults to show the Border. It can be changed using L_AnnSetTextOptions. |
Stamp (Bitmap) Border |
Defaults to Show a red border, width .75 pt, around bitmap stamp objects. It can be changed using LAnnSetStampBorder. |
Expand Tokens |
Defaults to expand tokens. It can be changed using the L_AnnSetTextExpandTokens function. |
Bitmap |
Defaults to Empty. It can be changed using the L_AnnSetBitmap function. |
Metafile |
