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