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;  TIFFReadEncoded-
       Strip returns -1 if an error was encountered.

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