方式一、Asprise-OCR的使用。

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寫的引用要在程式中用DllImport引用,關鍵程式碼:
[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);
