|  | TWAIN.h -  This is the definitive include file for applications and | 
|  | data sources written to the TWAIN specification. | 
|  | It defines constants, data structures, messages etc. | 
|  | for the public interface to TWAIN. | 
|  |  | 
|  | Revision History: | 
|  | version 1.0, March 6, 1992.  TWAIN 1.0. | 
|  | version 1.1, January 1993.   Tech Notes 1.1 | 
|  | version 1.5, June 1993.      Specification Update 1.5 | 
|  | Change DC to TW | 
|  | Change filename from DC.H to TWAIN.H | 
|  | version 1.5, July 1993.      Remove spaces from country identifiers | 
|  |  | 
|  | version 1.7, July 1997       Added Capabilities and data structure for | 
|  | document imaging and digital cameras. | 
|  | KHL. | 
|  | version 1.7, July 1997       Inserted Borland compatible structure packing | 
|  | directives provided by Mentor.  JMH | 
|  | version 1.7, Aug 1997        Expanded file tabs to spaces. | 
|  | NOTE: future authors should be sure to have | 
|  | their editors set to automatically expand tabs | 
|  | to spaces (original tab setting was 4 spaces). | 
|  | version 1.7, Sept 1997       Added job control values | 
|  | Added return codes | 
|  | version 1.7, Sept 1997       changed definition of pRGBRESPONSE to | 
|  | pTW_RGBRESPONSE | 
|  | version 1.7  Aug 1998        Added missing TWEI_BARCODEROTATION values | 
|  | TWBCOR_ types JMH | 
|  | version 1.8  August 1998     Added new types and definitions required | 
|  | for 1.8 Specification JMH | 
|  | version 1.8  January 1999    Changed search mode from SRCH_ to TWBD_ as | 
|  | in 1.8 Specification, added TWBT_MAXICODE	JMH | 
|  | version 1.8  January 1999    Removed undocumented duplicate AUTO<cap> JMH |
