NAME
       TIFFWritedEncodedStrip - compress and write a strip of data to an open
       TIFF file

SYNOPSIS
       #include <tiffio.h>
       tsize_t TIFFWriteEncodedStrip(TIFF* tif, tstrip_t strip, tdata_t	 buf,
       tsize_t size)

DESCRIPTION
       Compress	 size  bytes of raw data from buf and write the result to the
       specified strip; replacing any previously written data.	Note that 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
       places (PlanarConfiguration=2).

NOTES
       The  library  writes encoded data using the native machine byte order.
       Correctly implemented TIFF readers are expected to  do  any  necessary
       byte-swapping  to  correctly  process  image  data  with BitsPerSample
       greater than 8.

       The strip number must be valid according to the	current	 settings  of
       the  ImageLength	 and  RowsPerStrip tags.  An image may be dynamically
       grown by increasing the value of ImageLength prior  to  each  call  to
       TIFFWriteEncodedStrip.

RETURN VALUES
       -1  is  returned if an error was encountered.  Otherwise, the value of
       size is returned.

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

       %s: File not open for writing.  The file was opened for	reading,  not
       writing.

       Can  not write scanlines to a tiled image.  The image is assumed to be
       organized in tiles because the TileWidth and TileLength tags have been
       set with TIFFSetField(3T).

       %s:  Must set "ImageWidth" before writing data.	The image’s width has
       not be set before the first write.  See TIFFSetField(3T) for  informa-
       tion on how to do this.

       %s: Must set "PlanarConfiguration" before writing data.	The organiza-
       tion of data has not be defined before the first write.	See  TIFFSet-
       Field(3T) for information on how to do this.

       %s:  No	space  for strip arrays".  There was not enough space for the
       arrays that hold strip offsets and byte counts.
