The value of <i>strip</i> is a ``raw strip number.'' That
|
|
|
|
|
is, the caller must take into account whether or not the
|
|
|
|
|
data are organized in separate planes
|
|
|
|
|
(<i>PlanarConfiguration</i>=2). To read a full strip of data
|
|
|
|
|
the data buffer should typically be at least as large as the
|
|
|
|
|
number returned by <i>TIFFStripSize</i>(3T).</td></table>

The library attempts to hide bit- and byte-ordering
|
2002-10-07 09:47:36 -04:00
|
|
|
differences between the image and the native machine by
|
|
|
|
|
converting data to the native machine order. Bit reversal is
|
|
|
|
|
done if the <i>FillOrder</i> tag is opposite to the native
|
|
|
|
|
machine bit order. 16- and 32-bit samples are automatically
|
|
|
|
|
byte-swapped if the file was written with a byte order
|
2003-11-27 10:07:01 -05:00
