#include "ltdoc2.h"

L_LTDOC2_API L_INT EXT_FUNCTION L_Doc2FindDefaultFillMethod(hDoc, nPageIndex, pFillMethod)

Gets the default fill method of all zones in the specified page.

Parameters

L_HDOC2 hDoc

Handle to the OCR document.

L_INT nPageIndex

Specify the page index. This is a zero-based index.

DOC2_FILLMETHOD * pFillMethod

Pointer to a DOC2_FILLMETHOD enumerated type to be updated with the default fill method.

Returns

Comments

This function tries to determine the type of content in the OCR zones of a page.

The function only looks into zones with the DOC2_FILL_DEFAULT value in their ZONEDATA2.FillMethod field. The detected fill method is updated in the pFillMethod variable. If you call this function with NULL for the pFillMethod parameter, the function performs a zone-by-zone analysis (instead of suggesting a general filling type for the entire image), and if the algorithm can determine a type for a given zone, the function replaces the DOC2_FILL_DEFAULT value in the zone's ZONEDATA2.FillMethod field by the determined one.
