<i>TIFFDefaultStripSize</i> returns the number of rows for a
reasonable-sized strip according to the current settings of
the <i>ImageWidth</i>, <i>BitsPerSample</i>,
<i>SamplesPerPixel</i>, tags and any compression-specific
requirements. If the <i>estimate</i> parameter, if non-zero,
then it is taken as an estimate of the desired strip size
and adjusted according to any compression-specific
requirements. The value returned by this function is
typically used to define the <i>RowsPerStrip</i> tag. In
lieu of any unusual requirements <i>TIFFDefaultStripSize</i>
tries to create strips that have approximately 8 kilobytes
of uncompressed data.</td></table>

<i>TIFFComputeStrip</i> returns the strip that contains the
specified coordinates. A valid strip is always returned;
out-of-range coordinate values are clamped to the bounds of
the image. The <i>row</i> parameter is always used in
calculating a strip. The <i>sample</i> parameter is used
only if data are organized in separate planes
(<i>PlanarConfiguration</i>=2).</td></table>
