TIFFWriteEncodedStrip(3TIFF) TIFFWriteEncodedStrip(3TIFF)
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
planes (
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(3TIFF) 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(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 strip arrays". There was not enough space for the
arrays that hold strip offsets and byte counts.
