.TH TIFFReadEncodedStrip 3T "October 15, 1995"
.SH NAME
TIFFReadEncodedStrip \- read and decode a strip of data from an open
.SM TIFF
file
.SH SYNOPSIS
.B "#include <tiffio.h>"
.br
.B "tsize_t TIFFReadEncodedStrip(TIFF* tif, tstrip_t strip, tdata_t buf, tsize_t size)"
.SH DESCRIPTION
Read the specified strip of data and place up to
.I size
bytes of decompressed information in the (user supplied) data buffer.
.SH NOTES
The value of
.I strip
is a ``raw strip number.''
That is, the caller must take into account whether or not the
data are organized in separate planes (\c
.IR PlanarConfiguration =2).
To read a full strip of data the data buffer should typically be
at least as large as the number returned by
.IR TIFFStripSize (3T).
.PP
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
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,
.SH "RETURN VALUES"
The actual number of bytes of data that were placed in
.I buf
is returned;
.IR TIFFReadEncodedStrip
returns \-1 if an error was encountered.
.SH DIAGNOSTICS
All error messages are directed to the
.IR TIFFError (3T)
routine.

.IR TIFFOpen (3T),
.IR TIFFReadRawStrip (3T),
