<para><literal>TIFFDefaultStripSize</literal> returns the number of rows for

a reasonable-sized strip according to the current settings of the <literal>

ImageWidth</literal>, <literal>BitsPerSample</literal>, and <literal>SamplesPerPixel

</literal> tags, and any compression-specific requirements. If the <literal>

estimate</literal> parameter is 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 <literal>RowsPerStrip</literal> tag. In lieu of any unusual requirements, <literal>

TIFFDefaultStripSize</literal> tries to create strips that have approximately

8 kilobytes of uncompressed data.</para>

<para><literal>TIFFStripSize</literal> returns the equivalent size for a strip

of data as it would be returned in a call to <literal>TIFFReadEncodedStrip

</literal> or as it would be expected in a call to <literal>TIFFWriteEncodedStrip

</literal>.</para>

<para><literal>TIFFVStripSize</literal> returns the number of bytes in a strip

with <literal>nrows</literal> rows of data.</para>

<para><literal>TIFFComputeStrip</literal> 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 <literal>row

</literal> parameter is always used in calculating a strip. The <literal>

sample</literal> parameter is used only if data is organized in separate planes

(PlanarConfiguration=2).</para>

<para><literal>TIFFNumberOfStrips</literal> returns the number of strips in

the image.</para>
