nPageNum	UINT	Page number for which to get the count of tiles.

lpTileCountV	LPUINT	Pointer to a UINT variable to receive the number of tiles vertically (number of tiles in a column).

Return Value:

	Copy Code
UINT nTileRows; // Will receive number of tile rows UINT nTileCols; // Will receive number of tile cols AT_ERRCOUNT nErrcount; // Returned count of errors // Get number of tiles, first page of file: nErrcount = IG_tile_count_get("picture_tiled.tif", 1, &nTileRows, &nTileCols );

Copy Code

UINT nTileRows;            // Will receive number of tile rows
UINT nTileCols;            // Will receive number of tile cols
AT_ERRCOUNT nErrcount;  // Returned count of errors
// Get number of tiles, first page of file: 
nErrcount = IG_tile_count_get("picture_tiled.tif", 1, &nTileRows, &nTileCols );
