나는 .NET에서 스캔 (c# 버전 4.0, 비주얼 스튜디오 2010)을 필요로하는 응용 프로그램을 쓰고 있어요. 스캔을 수행하기 위해 TWAIN API를 사용하고 있는데 레이아웃 기능에 문제가 있습니다. 다음 코드는 Microtek i800하는 CanoScan 9000F과 Microtek Artix Scan F2에 완벽하게 잘 작동하지만 난 정말 Epson Perfection V700 뭔가에 대해 그것을 실행할 때 이상이 발생합니다. 내가 0에 이미지의 왼쪽 가장자리를 레이아웃의 왼쪽 여백을 설정하고 있지만 TWAIN에서 스캐너가 영역을 전체 너비로 설정하도록 할 수 있습니까?
그래서 제 질문은 ...입니다
사람이 나는 그것이 전체 너비를 스캔 할 수있는 방법을 알고 있나요 ? TWAIN에 용지 크기를 잊어 버릴 수있는 다른 설정이 있습니까? (PaperDetectable을 false로 설정하려고했지만 아무런 차이가 없었습니다.)
또 한가지 : 나는 레이아웃을 설정하지 않으면 은 여전히 가장자리 (바로 아래 위로가 아닌)에 그림을 차단하지만 나는 또한에 빛을 설정 (또는하지 않으면 난 몰라 - 반드시 그 ISN 특히 가장 왼쪽 가장자리에서 전체 사진을 검색합니다 (그러나 문제가 정말 빛과 스캔의 전체 폭을 필요가있다 : 그것은 내가 무엇을 기대하지)에 빛을 설정하지만 크기를 설정 할 너무 많이 묻지 마라.). 여기
은 (는 코드가에 하나의 버튼으로 1 개 형태의 윈도우 폼 응용 프로그램 뒤에있다) 코드입니다 : 여기에 완성도를 들어
