TIFFWriteEncodedTile(3T)             Image Format Library C++ Reference Manual



NAME
     TIFFWritedEncodedTile - compress and write a tile of data to an open TIFF
     file

SYNOPSIS
     #include <tiffio.h>
     tsizet TIFFWriteEncodedTile(TIFF* tif, ttilet tile, tdatat buf,
     tsizet size)

DESCRIPTION
     Compress size bytes of raw data from buf and append the result to the end
     of the specified tile.  Note that the value of tile is a ``raw tile
     number.''  That is, the caller must take into account whether or not the
     data are organized in separate places (PlanarConfiguration=2).
     TIFFComputeTile automatically does this when converting an (x,y,z,sample)
     coordinate quadruple to a tile number.

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.

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 tiles to a stripped image.  The image is assumed to be
     organized in strips because neither of the TileWidth or 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 information on
     how to do this.

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

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