<H2>DESCRIPTION</H2>

<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.
<P>

<I>TIFFStripSize</I>

returns the equivalent size for a strip of data as it would
be returned in a call to
<I>TIFFReadEncodedStrip</I>

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

<P>

<I>TIFFVStripSize</I>

returns the number of bytes in a strip with
<I>nrows</I>

rows of data.
<P>

<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).

<P>

<I>TIFFNumberOfStrips</I>

returns the number of strips in the image.
