.TH TIFFWriteEncodedTile 3TIFF "December 16, 1991" "libtiff"

.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.
