Detects Magnetic Ink Character Recognition (MICR) zones on a bitmap, using a specified set of options.
#include "l_bitmap.h"
L_LTIMGCOR_API L_INT L_MICRDetectionEXT(pBitmap, pOptions, uFlags)
The reference to the bitmap.
The specified options passed to the detection.
Reserved for future use. Pass 0.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
Specify the rcInputROI in the MICRCODEDETECTOROPTIONS structure to detect the MICR zone.
This function processes only the region specified by the rcInputROI. It does not support regions.
This function supports 8-, 12-, and 16-bit grayscale images and 24- and 32-bit color images.
Win32, x64, Linux.
This example loads a bitmap and applies MICR detection with a specified set of options.
