NAME
       TIFFReadEncodedStrip - read and decode a strip of data from an open
       TIFF file

SYNOPSIS
       #include <tiffio.h>

       tsize_t TIFFReadEncodedStrip(TIFF *tif, tstrip_t strip, tdata_t buf,
       tsize_t size)

DESCRIPTION
       Read the specified strip of data and place up to size bytes of
       decompressed information in the (user supplied) data buffer.

NOTES
       The value of strip is a ``raw strip number.''  That is, the caller must
       take into account whether or not the data are organized in separate
       planes (PlanarConfiguration=2).  To read a full strip of data the data
       buffer should typically be at least as large as the number returned by
       TIFFStripSize(3TIFF).  If the -1 passed in size parameter, the whole
       strip will be read. You should be sure you have enough space allocated
       for the buffer.

       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 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,

RETURN VALUES
       The actual number of bytes of data that were placed in buf is returned;
       TIFFReadEncodedStrip returns -1 if an error was encountered.

DIAGNOSTICS
       All error messages are directed to the TIFFError(3TIFF) routine.
