NAME
     TIFFtile,  TIFFTileSize,   TIFFTileRowSize,   TIFFVTileSize,
     TIFFDefaultTileSize,     TIFFComputeTile,     TIFFCheckTile,
     TIFFNumberOfTiles - tile-related utility routines

SYNOPSIS
     #include 
     void TIFFDefaultTileSize(TIFF* tif, uint32* tw, uint32* th)
     tsize_t TIFFTileSize(TIFF* tif)
     tsize_t TIFFTileRowSize(TIFF* tif)
     tsize_t TIFFVTileSize(TIFF* tif, uint32 nrows)
     ttile_t TIFFComputeTile(TIFF* tif, uint32 x, uint32 y, uint32 z, tsample_t sample)
     int TIFFCheckTile(TIFF* tif, uint32 x, uint32 y, uint32 z, tsample_t sample)
     ttile_t TIFFNumberOfTiles(TIFF* tif)



     TIFFDefaultTileSize returns the pixel width and height of  a
     reasonable-sized tile, suitable for setting up the TileWidth
     and TileLength tags. If the tw and th values passed  in  are
     non-zero,   then   they   are   adjusted   to   reflect  any
     compression-specific requirements. The  returned  width  and
     height  are  constrained  to  be a multiple of 16 pixels, to
     conform with the TIFF specification.

     TIFFTileSize returns the equivalent size for a tile of  data
     as  it  would be returned in a call to TIFFReadTile or as it
     would be expected in a call to TIFFWriteTile.

     TIFFVTileSize returns the number of bytes in  a  row-aligned
     tile with nrows of data.

     TIFFTileRowSize returns the number of bytes of a row of data
     in a tile.

     TIFFComputeTile returns the tile that contains the specified
     coordinates.  A  valid tile is always returned. Out-of-range
     coordinate values are clamped to the bounds  of  the  image.
     The  x  and  y  parameters  are always used in calculating a
     tile. The z parameter is used if the image is deeper than  1
     slice  (ImageDepth>1).  The sample parameter is used only if
     data  is  organized  in  separate  planes  (PlanarConfigura-
     tion=2).

     TIFFCheckTile returns a non-zero value if the supplied coor-
     dinates  are within the bounds of the image, and zero other-
     wise. The x parameter is checked against the  value  of  the
     ImageWidth  tag.   The  y  parameter  is checked against the
     value of the ImageLength tag. The  z  parameter  is  checked
     against  the  value  of the ImageDepth tag (if defined). The
     sample parameter is checked against the value  of  the  Sam-
     plesPerPixel  parameter if the data is organized in separate

     TIFFNumberOfTiles returns the number of tiles in the image.
