DOC2_FILLMETHOD * pFillMethod;	/* pointer to default fill method */

Gets the default fill method for the specified page.

Parameter	Description
hDoc	Handle to the OCR document.
nPageIndex	Specify the page index. This is a zero-based index.
pFillMethod	Pointer to a DOC2_FILLMETHOD enumerated type to be updated with the default fill method.

Returns

SUCCESS	The function was successful.

Comments

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

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.
