NAME

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

SYNOPSIS

#include <tiffio.h>

tsize_t TIFFWriteEncodedTile(TIFF *tif, ttile_t tile, tdata_t buf,
tsize_t 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(3TIFF) 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(3TIFF).

%s: Must set "ImageWidth" before writing data. The image's width has
not be set before the first write. See TIFFSetField(3TIFF) 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(3TIFF) 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.
