<p><big>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.</big></p>
|
|
<!-- INDENTATION -->
|
|
<p><big>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,</big></p>
