Detailed Description

Table detection and working with tables.

This module detects tables on the page and connects the recognition result and the table information to each other.

A table is described by the list of its cells in reading order (from left to right and top to bottom) ordered by their top-left coordinates. A cell is always a rectangle, thus a table is a sequence of rectangles.

All cell operations must adhere to the following restrictions:

• cells cannot have blank spaces in between,
• cells cannot intersect each other
• all cells must have a rectangular shape.

NOTE: In both the SDK and its documentation, coordinates refer to grid-coordinates - i.e. the top or left borders of pixels. Thus a rectangle does not contain the pixels according to its right and bottom coordinates.

Table information in a table zone (WT_TABLE) contains the above mentioned table description. (See CELL_INFO.) The structure of a table zone can be determined in three different ways:

• User-defined: creating a one-cell table structure (kRecCreateTableInfo) into a WT_TABLE user zone. Having such table information the User can insert splitters into it (kRecSplitCells), or can replace the cell list with a User-defined cell sequence (kRecSetCells). Note that kRecSetCells creates the table information, if kRecCreateTableInfo has not run before.
• User-started: calling kRecLocateTable for a WT_TABLE user zone before recognition. The module automatically detects the structure of the table covered by the given zone and creates the table information.
• Engine-controlled: the recognition process automatically detects and creates the table information for all such WT_TABLE user zones that have not been processed by the previous two methods and for all the automatically detected table type OCR zones.

The User-started method is less accurate than the Engine-controlled one, thus it may be useful only when automatic cell detection is required before recognition (mainly for displaying on the UI).

The Engine-controlled method leaves the existing cell sequence, if any. In contrast, the User-started method recreates the cell sequence of the user zone even if the zone contains previous table information.

It follows from the above that the Engine-controlled method can be disabled by calling kRecCreateTableInfo.

The table detection algorithm can recognize tables both with (gridded table) and without visible grid lines (non-gridded table). While the algorithm can unconditionally detect gridded tables, detecting non-gridded tables is not supported when applying any of the following recognition languages: Arabic, Simplified Chinese, Traditional Chinese, Hebrew, Japanese, and Korean. The application can control whether non-gridded tables should also be detected by the function kRecSetNongriddedTableDetect.

Function Documentation

kRecCreateTableInfo()

RECERR RECAPIKRN kRecCreateTableInfo	(	HPAGE	hPage,
		int	xZone )

Creating table information.

The kRecCreateTableInfo function creates table information for a user zone. The resulting table info has only one cell with the size of the whole table. This is required, because the cell manipulating functions work for user zones having table information (kRecSplitCells, kRecMergeCells, kRecMoveCellBorder, kRecDragCellBorder, kRecSetCellColor).

Parameters

[in]	hPage	Handle of the page.
[in]	xZone	Index of the zone in the user zone list.

Return values

RECERR

Note

The index of the first zone in the zone list is zero (0).

See the description of table info creation.
