<h2>NOTES</h2>

|
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">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 <b>TIFFStripSize</b>(3TIFF).
|
|
|
|
|
If the -1 passed in <i>size</i> parameter, the whole strip
|
|
|
|
|
will be read. You should be sure you have enough space
|
|
|
|
|
allocated for the buffer.</p>
|
|
|
|
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">The library
|
|
|
|
|
attempts to hide bit- and byte-ordering 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 opposite to the
|
|
|
|
|
native machine byte order,</p>
