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 compatibile 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
