+<p><i>TIFFDefaultTileSize</i> returns the pixel width and
+height of a reasonable-sized tile; suitable for setting up
+the <i>TileWidth</i> and <i>TileLength</i> tags. If the
+<i>tw</i> and <i>th</i> 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
+<small>TIFF</small> specification.</p>
+<!-- INDENTATION -->
+<p><i>TIFFTileSize</i> returns the equivalent size for a
+tile of data as it would be returned in a call to
+<i>TIFFReadTile</i> or as it would be expected in a call to
+<i>TIFFWriteTile</i>.</p>
+<!-- INDENTATION -->
+<p><i>TIFFVTileSize</i> returns the number of bytes in a
+row-aligned tile with <i>nrows</i> of data.</p>
+<!-- INDENTATION -->
+<p><i>TIFFTileRowSize</i> returns the number of bytes of a
+row of data in a tile.</p>
+<!-- INDENTATION -->
+<p><i>TIFFComputeTile</i> 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 <i>x</i> and <i>y</i> parameters are always
+used in calculating a tile. The <i>z</i> parameter is used
+if the image is deeper than 1 slice
+(<i>ImageDepth</i>&gt;1). The <i>sample</i> parameter is
+used only if data are organized in separate planes
+(<i>PlanarConfiguration</i>=2).</p>
+<!-- INDENTATION -->
+<p><i>TIFFCheckTile</i> returns a non-zero value if the
+supplied coordinates are within the bounds of the image and
+zero otherwise. The <i>x</i> parameter is checked against
+the value of the <i>ImageWidth</i> tag. The <i>y</i>
+parameter is checked against the value of the
+<i>ImageLength</i> tag. The <i>z</i> parameter is checked
+against the value of the <i>ImageDepth</i> tag (if defined).
+The <i>sample</i> parameter is checked against the value of
+the <i>SamplesPerPixel</i> parameter if the data are
+organized in separate planes.</p>
+<!-- INDENTATION -->
+<p><i>TIFFNumberOfTiles</i> returns the number of tiles in
+the image.</p>
