- <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>>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>
