public: string* MICRDoMICR( 
   int ImageID,
   MICRFont SymbolsFont,
   MICRContext context,
   string* WhiteList,
   int ExpectedSymbols
)

public:
String^ MICRDoMICR( 
   int ImageID,
   MICRFont SymbolsFont,
   MICRContext context,
   String^ WhiteList,
   int ExpectedSymbols
)

Parameters

ImageID: GdPicture image identifier.
SymbolsFont: A member of the MICRFont enumeration.
context: The MICR context. A member of the MICRContext enumeration.
WhiteList: This parameter can be used to specify your own white list of chars. Can be any members of "0123456789/<#>^ABCDEFGHIJKLMNOPQRSTUVWXYZ" for CMC7 symbols detection or "0123456789ABCD" for E-13B. Use empty string to recognize all characters.
ExpectedSymbols: The number of expected symbols to detect. Use 0 if this number is undefined.

Return Value

The string representation of the detected symbols.

Remarks

This method is used in the "MICR" Demo.

Use the GetStat() method to determine if this method succeeded.

This method requires the MICR component to run.

Example

Reading an MICR line within a jpeg image.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    string whiteList = "0123456789/<#>^ABCDEFGHIJKLMNOPQRSTUVWXYZ";
 
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg");
 
    // Read the CMC7 line contained in the image.
    string text = gdpictureImaging.MICRDoMICR(imageID, MICRFont.MICRFontCMC7, MICRContext.MICRContextLineFinding, whiteList, whiteList.Length);
    gdpictureImaging.MICRClear();
    gdpictureImaging.ReleaseGdPictureImage(imageID);
 
    MessageBox.Show(text, "MICR", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
