TWAIN 2.0 및 하이 레벨 함수들

LEADTOOLS는 TWAIN 하이레벨 함수들을 제공합니다. 이 함수들은 대부분 자주 사용되는 기능들을 결정하며 TWAIN 사양을 획득/인지하거나 또는 TWAIN 기능들을 설정하기 위한 필요성을 제거해 줍니다.

TWAIN 전용 : LEADTOOLS 또는 TWAIN 드라이버들과 상호 작용하는 로우 레벨 인터페이스를 포함합니다.

LEADTOOLS 하이 레벨 함수들은 다음과 같은 기능들을 결정합니다 :

• ICAP_XFERMECH: Transfer Mechanism (Native/Memory Buffered/File)
• ICAP_IMAGEFILEFORMAT: Image File Format (BMP, JPEG, TIFF, etc)
• ICAP_COMPRESSION: Image compression (Group4, JPEG, LZW, etc)
• ICAP_XRESOLUTION: Image's X Resolution or Dots Per Inch
• ICAP_YRESOLUTION: Image's Y Resolution or Dots Per Inch
• ICAP_FRAMES: Dimensions at which to scan the image
• ICAP_UNITS: Unit of measure for all quantities
• ICAP_BITDEPTH: Image's Bitdepth
• ICAP_BRIGHTNESS: Image's Brightness
• ICAP_CONTRAST: Image's Contrast
• ICAP_HIGHLIGHT: Image's Hightlight
• ICAP_ORIENTATION: Image's Orientation
• ICAP_SUPPORTEDSIZES: Predefined dimensions at which to scan the image
• DG_IMAGE / DAT_RGBRESPONSE / MSG_RESET:
• DG_IMAGE / DAT_RGBRESPONSE / MSG_SET
• CAP_INDICATORS: Turns the status bar on and off
• CAP_DUPLEXENABLED: Enables/Disables Duplex scanning
• CAP_DUPLEX: Tells what Duplex is supported by the scanner
• CAP_XFERCOUNT: Tells the scanner how many pages to scan
