TIFFWriteEncodedStrip(3T)                            TIFFWriteEncodedStrip(3T)



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.
