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.
