<p><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>

<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>

<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>
