NAME

       TIFFWriteTile - encode and write a tile of data to an open TIFF file

SYNOPSIS

       #include <tiffio.h>

       tsize_t TIFFWriteTile(TIFF *tif, tdata_t buf, uint32 x, uint32 y, uint32 z, tsample_t sample)

DESCRIPTION

       Write the data for the tile containing the specified coordinates. The data in buf are is (potentially) compressed, and written to the indi-
       cated file, normally being appended to the end of the file. The buffer must be contain an entire tile of data. Applications should call the
       routine	TIFFTileSize  to  find	out  the size (in bytes) of a tile buffer. The x and y parameters are always used by TIFFWriteTile.  The z
       parameter is used if the image is deeper than 1 slice (ImageDepth>1).  The sample parameter is used only if data are organized in  separate
       planes (PlanarConfiguration=2).

RETURN VALUES

       TIFFWriteTile returns -1 if it detects an error; otherwise the number of bytes in the tile is returned.

DIAGNOSTICS

       All error messages are directed to the TIFFError(3TIFF) routine.

NAME

       TIFFTileSize, TIFFTileRowSize, TIFFVTileSize, TIFFDefaultTileSize, TIFFComputeTile, TIFFCheckTile, TIFFNumberOfTiles - tile-related utility
       routines

SYNOPSIS

       #include <tiffio.h>

       void TIFFDefaultTileSize(TIFF *tif, uint32 *tw, uint32 *th)
       tsize_t TIFFTileSize(TIFF *tif)
       tsize_t TIFFTileRowSize(TIFF *tif)
       tsize_t TIFFVTileSize(TIFF *tif, uint32 nrows)
       ttile_t TIFFComputeTile(TIFF *tif, uint32 x, uint32 y, uint32 z, tsample_t sample)
       int TIFFCheckTile(TIFF *tif, uint32 x, uint32 y, uint32 z, tsample_t sample)
       ttile_t TIFFNumberOfTiles(TIFF *tif)

DESCRIPTION

       TIFFDefaultTileSize returns the pixel width and height of a reasonable-sized tile; suitable for setting up  the	TileWidth  and	TileLength
       tags.   If  the	tw  and  th  values  passed  in are non-zero, then they are adjusted to reflect any compression-specific requirements. The
       returned width and height are constrained to be a multiple of 16 pixels to conform with the TIFF specification.

       TIFFTileSize returns the equivalent size for a tile of data as it would be returned in a call to TIFFReadTile or as it would be expected in
       a call to TIFFWriteTile.

       TIFFVTileSize returns the number of bytes in a row-aligned tile with nrows of data.

       TIFFTileRowSize returns the number of bytes of a row of data in a tile.

       TIFFComputeTile	returns  the tile that contains the specified coordinates. A valid tile is always returned; out-of-range coordinate values
       are clamped to the bounds of the image. The x and y parameters are always used in calculating a tile. The z parameter is used if the  image
       is deeper than 1 slice (ImageDepth>1).  The sample parameter is used only if data are organized in separate planes (PlanarConfiguration=2).

       TIFFCheckTile  returns  a non-zero value if the supplied coordinates are within the bounds of the image and zero otherwise. The x parameter
       is checked against the value of the ImageWidth tag. The y parameter is checked against the value of the ImageLength tag. The z parameter is
       checked	against  the  value  of  the ImageDepth tag (if defined). The sample parameter is checked against the value of the SamplesPerPixel
       parameter if the data are organized in separate planes.

       TIFFNumberOfTiles returns the number of tiles in the image.

DIAGNOSTICS

       None.
