.SH NAME
|
|
TIFFWritedEncodedTile \- compress and write a tile of data to an open
|
|
.SM TIFF
|
|
file
|
|
.SH SYNOPSIS
|
|
.B "#include <tiffio.h>"
|
|
.sp
|
|
.BI "tsize_t TIFFWriteEncodedTile(TIFF *" tif ", ttile_t " tile ", tdata_t " buf ", tsize_t " size ")"
|
|
.SH DESCRIPTION
|
|
Compress
|
|
.I size
|
|
bytes of raw data from
|
|
.I buf
|
|
and
|
|
.B append
|
|
the result to the end of the specified tile. Note that the value of
|
|
.I tile
|
|
is a ``raw tile number.'' That is, the caller must take into account whether
|
|
or not the data are organized in separate places (\c
|
|
.IR PlanarConfiguration =2).
|
|
.IR TIFFComputeTile
|
|
automatically does this when converting an (x,y,z,sample) coordinate quadruple
|
|
to a tile number.
|
|
.SH NOTES
|
|
The library writes encoded data using the native machine byte order. Correctly
|
|
implemented
|
|
.SM TIFF
|
|
readers are expected to do any necessary byte-swapping to correctly process
|
|
image data with BitsPerSample greater than 8.
|
|
.SH "RETURN VALUES"
|
|
\-1 is returned if an error was encountered. Otherwise, the value of
|
|
.IR size
|
|
is returned.
|
|
.SH DIAGNOSTICS
|
|
All error messages are directed to the
|
|
.BR TIFFError (3TIFF)
|
|
routine.
|
|
.PP
|
|
\fB%s: File not open for writing\fP.
|
|
The file was opened for reading, not writing.
|
|
.PP
|
|
\fBCan not write tiles to a stripped image\fP.
|
|
The image is assumed to be organized in strips because neither of the
|
|
.I TileWidth
|
|
or
|
|
.I TileLength
|
|
tags have been set with
|
|
.BR TIFFSetField (3TIFF).
|
|
.PP
|
|
\fB%s: Must set "ImageWidth" before writing data\fP. The image's width has not
|
|
be set before the first write. See
|
|
.BR TIFFSetField (3TIFF)
|
|
for information on how to do this.
|
|
.PP
|
|
\fB%s: Must set "PlanarConfiguration" before writing data\fP. The organization
|
|
of data has not be defined before the first write. See
|
|
.BR TIFFSetField (3TIFF)
|
|
for information on how to do this.
|
|
.PP
|
|
\fB%s: No space for tile arrays"\fP.
|
|
There was not enough space for the arrays that hold tile offsets and byte
|
|
counts.
