方式一、Asprise-OCR的使用。

Asprise-OCR下載地址：

其中需要使用的3個dll是AspriseOCR.dll、DevIL.dll、ILU.dll。

需要注意的是這幾個.dll是vc寫的引用要在程序中用DllImport引用，關鍵代碼：

[DllImport("AspriseOCR.dll",?EntryPoint?=?"OCR",?CallingConvention?=?CallingConvention.Cdecl)]

public?static?extern?IntPtr?OCR(string?file,?int?type);

[DllImport("AspriseOCR.dll",?EntryPoint?=?"OCRpart",?CallingConvention?=?CallingConvention.Cdecl)]

static?extern?IntPtr?OCRpart(string?file,?int?type,?int?startX,?int?startY,?int?width,?int?height);

[DllImport("AspriseOCR.dll",?EntryPoint?=?"OCRBarCodes",?CallingConvention?=?CallingConvention.Cdecl)]

static?extern?IntPtr?OCRBarCodes(string?file,?int?type);

[DllImport("AspriseOCR.dll",?EntryPoint?=?"OCRpartBarCodes",?CallingConvention?=?CallingConvention.Cdecl)]

static?extern?IntPtr?OCRpartBarCodes(string?file,?int?type,?int?startX,?int?startY,?int?width,?int?height);
