The Annotation Text Token Table

(Document and Medical Imaging toolkits)

This feature applies to the text annotation objects that support tokens:

A token is a special text string that can be translated into another more meaningful text string. For example, a user may wish to display the current date or the name of their company in their text annotations. Rather than type out the date or the name of the company, a text token can be typed instead.

Tokens are two-character strings of the form:

#{any character}

Any token (except for ##) can be defined to mean anything. LEAD defines the following set of constants to represent functions that can be mapped to any token.

ANNTOKEN_NONE

[0] String not treated as a token

ANNTOKEN_SEPARATOR

[1] Add a separator to the automation token menu

ANNTOKEN_TEXT

[2] A text string

ANNTOKEN_DATE_YYYY

[3] Current four digit year

ANNTOKEN_DATE_YY

[4] Current two digit year

ANNTOKEN_DATE_MM

[5] Two digit representation of current month

ANNTOKEN_DATE_DD

[6] Two digit representation of current day

ANNTOKEN_DATE_MONTH_NAME

[7] Current month name (for example, January)

ANNTOKEN_DATE_DAY_OF_WEEK

[8] Current day of week (for example, Monday)

ANNTOKEN_TIME_HH_12

[9] Current hour,using a 12 hour clock

ANNTOKEN_TIME_HH_24

[10] Current hour, using a 24 hour clock

ANNTOKEN_TIME_MM

[11] Current minute (00-59)

ANNTOKEN_TIME_SS

[12] Current second (00-59)

ANNTOKEN_TIME_MILLISECONDS

[13] Current milliseconds (000-999)

ANNTOKEN_AM_PM

[14] Time of day indicator (AM or PM)

LEAD defines a predefined text token table that you can use, or you can define your own. The predefined text tokens table is listed below.

Default Text Token Table

#Y 

"Four digit year"

#y 

"Two digit year"

#M 

"Two digit month"

#d 

"Two digit day"

#N 

"Month Name"

#D 

"Day of week name"

#h 

"Current time: 12-Hour (01-12),

#H 

"Current time: 24-Hour (00-23),

#m 

"Current time: minutes"

#s 

"Current time: seconds"

#f 

"Current time: milliseconds "

#t 

"Current time: AM or PM"

## 

"#"

The text token table is displayed in the automation text dialog. The following figure displays the default text token table.

The default annotation text token table can be easily changed using the following functions:

L_AnnClearTextTokenTable

L_AnnDeleteTextTokenTable

L_AnnEnumerateTextTokenTable

L_AnnGetTextExpandTokens

L_AnnInsertTextTokenTable

L_AnnSetTextExpandTokens

Use L_AnnClearTextTokenTable to remove all tokens from the text token table.

Use L_AnnDeleteTextTokenTable to delete a text token from the annotation text token table.

Use L_AnnEnumerateTextTokenTable to examine the contents of the annotation text token table.

Use L_AnnGetTextExpandTokens to get the text expand token property of an annotation.

Use L_AnnInsertTextTokenTable to insert a text token into the text token table.

Use L_AnnSetTextExpandTokens to set the text expand token property of an annotation.

Additionally, you can define your own user-defined text tokens. User-defined text tokens can consist of new text strings, or any combination of existing text tokens. The following figure displays a user-defined text token table.
