L_AutoPageSplitter

#include "Ltimgcor.h"

L_LTIMGCOR_API L_INT L_AutoPageSplitter(pBitmap, pOutBitmap, SplittingCoord)

pBITMAPHANDLE pBitmap;	pointer to the bitmap handle
pBITMAPHANDLE pOutBitmap;	pointer to a BITMAPHANDLE[2] array.
L_UINT* SplittingCoord;	pointer to a L_UINT variable that will be filled with the column number of the splitting point

Automatically splits document images that have two pages inside it.

Parameter	Description
pBitmap	Pointer to the bitmap handle referencing the bitmap to be splitted.
pOutBitmap	Pointer to a BITMAPHANDLE[2] array. The first element will be filled with the left page, and the second element with the right page.
SplittingCoord	Pointer to a L_UINT variable that will be filled with the column number of the splitting point.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Finds and splits a two-page document that has its pages horizontally side-by-side.

The two new bitmaps have the same dimensions as the original.

The new bitmaps are returned as 1-bit bitmaps.

This function can only process entire images. It does not support regions.

This function supports 24- and 36-bit color images and 8-bit grayscale images.
