(Document and Medical Imaging toolkits)
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. |
ROP2 code |
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. |
Foreground color |
Defaults to red. It can be changed using the L_AnnSetForeColor function. |
Transparent option |
Defaults To Do Not Use Transparent Color. It can be changed using the L_AnnSetTransparent function. |
Transparent Color |
Defaults to White. It can be changed using the L_AnnSetTransparentColor function. |
Background color |
Defaults to white. It can be changed using the L_AnnSetBackColor function. The default does not affect highlight, redaction, or note objects. |
Font size |
Defaults to 10 point, translated with a scaling factor of 1. It can be changed using the L_AnnSetFontSize function. |
Font underline |
Defaults to FALSE. It can be changed using the L_AnnSetFontUnderline function. |
Font strikethrough |
Defaults to FALSE. It can be changed using the L_AnnSetFontStrikeThrough function. |
Font italic |
Defaults to FALSE. It can be changed using the L_AnnSetFontItalic function. |
Font bold |
Defaults to FALSE. It can be changed using the L_AnnSetFontBold function. |
Font name |
Defaults to "Arial". It can be changed using the L_AnnSetFontName function. |
Text |
Defaults to "AaBbYyZz". It can be changed using the L_AnnSetText function. |
Text Displayed* |
Defaults to Show text. It can be changed using L_AnnSetTextOptions. |
Text Color* |
Defaults to red (RGB(255,0,0). It can be changed using L_AnnSetTextOptions. |
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 |
Defaults to Empty. It can be changed using the L_AnnSetMetafile function. |
Fixed State |
Defaults to not fixed. It can be changed using the L_AnnSetFixed function. |
Hyperlink |
Defaults to None. It can be changed using the L_AnnSetHyperlink function. |
Tag (identifier) |
Defaults to 0. It can be changed using the L_AnnSetTag function. |
Window handle |
Defaults to NULL or the handle inherited from the container. It can be changed for all objects using the L_AnnSetWnd function. |
User mode |
Defaults to design mode or the mode inherited from the container. It can be changed for all objects using the L_AnnSetUserMode function. |
* Note: These features must be enabled using the L_AnnSetOptions function.
