SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function searches a given L_RECT zone in a document image for a MICR zone.
This function processes only the region specified by the InRect parameter. It does not support regions.
This function supports 8-, 12-, and 16-bit grayscale images and 24- and 32-bit color images.
Required DLLs and Libraries
Win32, x64, Linux.
This example loads a bitmap and applies MICR detection filter.
