TIFFWriteEncodedTile.3tiff - Man Page
compress and write a tile of data to an open TIFF file
Synopsis
#include <tiffio.h>
tsize_t TIFFWriteEncodedTile(TIFF *tif, ttile_t tile, tdata_t buf, tsize_t size)
Description
Compress size bytes of raw data from buf and append the result to the end of the specified tile. Note that the value of tile is a "raw tile number". That is, the caller must take into account whether or not the data are organized in separate planes (PlanarConfiguration = 2). TIFFComputeTile() automatically does this when converting an (x,y,z,sample) coordinate quadruple to a tile number.
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.
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 TIFFErrorExtR() routine.
%s: File not open for writing:
The file was opened for reading, not writing.
Can not write tiles to a stripped image:
The image is assumed to be organized in strips because neither of the TileWidth or TileLength tags have been set with TIFFSetField().
%s: Must set "ImageWidth" before writing data:
The image's width has not been set before the first write. See TIFFSetField() 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() for information on how to do this.
%s: No space for tile arrays":
There was not enough space for the arrays that hold tile offsets and byte counts.
