Stamp Annotation Object

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.

The class for Stamp Annotation objects is LAnnStamp.

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:

Property Default value
Visible Defaults to FALSE. It can be changed using the LAnnotation::SetVisible function.
Selected Defaults to FALSE. It can be changed using the LAnnotation::SetSelected function.
Name Defaults to an empty string. It can be changed using the LAnnotation::SetNameOptions function.
Line width Defaults to 0.75 points. It can be changed using the LAnnXXX::SetLineWidth 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 LAnnXXX::SetLineStyle function.
ROP2 code Defaults to ANNROP2_COPY. It can be changed using the LAnnotation::SetROP2 function.
Transparent option Defaults To Do Not Use Transparent Color. It can be changed using the LAnnStamp::SetTransparent function.
Transparent Color Defaults to White. It can be changed using the LAnnStamp::SetTransparentColor function.
Fill pattern Defaults to solid. It can be changed using the LAnnAutomation::SetFillPattern function.
Fill mode Defaults to transparent. It can be changed using the LAnnotation::SetFillMode function. Before calling this function enable the alpha background fill mode by calling the LAnnotation::SetOptions function.
Foreground color Defaults to red. It can be changed using the LAnnotation::SetForeColor function.
Background color Defaults to white. It can be changed using the LAnnXXX::SetBackColor function.
Font size Defaults to 10 point, translated with a scaling factor of 1. It can be changed using the LAnnXXX::SetFontSize function.
Font underline Defaults to FALSE. It can be changed using the LAnnXXX::SetFontUnderline function.
Font strikethrough Defaults to FALSE. It can be changed using the LAnnXXX::SetFontStrikethrough function.
Font italic Defaults to FALSE. It can be changed using the LAnnXXX::SetFontItalic function.
Font bold Defaults to FALSE. It can be changed using the LAnnXXX::SetFontBold function.
Font name Defaults to "Arial". It can be changed using the LAnnXXX::SetFontName function.
Text Defaults to "AaBbYyZz". It can be changed using the LAnnStamp::SetText function.
Text Displayed* Defaults to Show text. It can be changed using LAnnotation::SetTextOptions.
Text Color* Defaults to red (RGB(255,0,0). It can be changed using LAnnotation::SetTextOptions.
Text Border* Defaults to show the Border. It can be changed using LAnnotation::SetTextOptions.
Expand Tokens Defaults to expand tokens. It can be changed using the LAnnAutomation::SetTextExpandTokens function.
Bitmap Defaults to Empty. It can be changed using the LAnnStamp::SetBitmap function.
Metafile Defaults to Empty. It can be changed using the LAnnStamp::SetMetafile function.
Fixed State Defaults to not fixed. It can be changed using the LAnnXXX::SetFixed function.
Hyperlink Defaults to ANNLINK_NONE. It can be changed using the LAnnotation::SetHyperlink function.
Tag (identifier) Defaults to 0. It can be changed using the LAnnotation::SetTag function.
Window handle Defaults to NULL or the handle inherited from the container. It can be changed for all objects using LAnnContainer::SetWnd.
User mode Defaults to design mode or the mode inherited from the container. It can be changed for all objects using LAnnContainer::SetUserMode.
* These features must be enabled using the LAnnotation::SetOptions function.
