This documentation gives a detailed description of the Application
Programming
Interface
(API
) of the PR system. It contains the description of definitions, enumerations and functions for the ANSI C programming language.
The functionality of the Passport Reader is centered upon two base functions. The
Capture function takes images of the document at different lightnings and stores the binary data in computer understandable format (bitmap). The
Recognize function analyses the taken image and generates text data in computer understandable format (ascii/unicode). These representations can be later inserted in a database or processed by other user programs.
The functionality of the Passport Reader is groupped as following:
Next browse the groups list, check the prapi.h for full reference or check the Change Log in the reference manual for differences against the previous versions.
