DESCRIPTION

       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().   TIFFTileSize64()  returns  a
       uint64_t number.  If an error occurs, 0 is returned.

       TIFFVTileSize()  returns the number of bytes in a row-aligned tile with nrows of data.  TIFFVTileSize64()
       returns a uint64_t number.  If an error occurs, 0 is returned.

       TIFFTileRowSize() returns the number of bytes of a row of data in a tile.  TIFFTileRowSize64() returns  a
       uint64_t number.  If an error occurs, 0 is returned.

       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  are  organized  in  separate  planes
       (PlanarConfiguration = 2).

       TIFFCheckTile()  returns  a non-zero value if the supplied coordinates are within the bounds of the image
       and zero otherwise. 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  SamplesPerPixel
       parameter if the data are organized in separate planes.

       TIFFNumberOfTiles() returns the number of tiles in the image.
