TIFFReadEncodedTile(3TIFF)TIFFReadEncodedTile(3TIFF)NAME
TIFFReadEncodedTile - read and decode a tile of data from an open TIFF file
SYNOPSIS
#include <tiffio.h>
int TIFFReadEncodedTile(TIFF *tif, ttile_t tile, tdata_t buf, tsize_t size)
DESCRIPTION
Read the specified tile of data and place up to size bytes of decompressed information in the (user supplied) data buffer.
NOTES
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. To read a full tile of data the data buffer should be at least as large as the value returned by TIFFTileSize.
The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native
machine order. Bit reversal is done if the FillOrder tag is opposite to the native machine bit order. 16- and 32-bit samples are automati-
cally byte-swapped if the file was written with a byte order opposite to the native machine byte order,
RETURN VALUES
The actual number of bytes of data that were placed in buf is returned; TIFFReadEncodedTile returns -1 if an error was encountered.
DIAGNOSTICS
All error messages are directed to the TIFFError(3TIFF) routine.

TIFFReadRawTile - return an undecoded tile of data from an open TIFF file
SYNOPSIS
#include <tiffio.h>
tsize_t TIFFReadRawTile(TIFF *tif, ttile_t tile, tdata_t buf, tsize_t size)
DESCRIPTION
Read the contents of the specified tile into the (user supplied) data buffer. Note that the value of tile is a ``raw tile number.'' That
is, the caller must take into account whether or not the data is organized in separate planes (PlanarConfiguration=2). TIFFComputeTile
automatically does this when converting an (x,y,z,sample) coordinate quadruple to a tile number. To read a full tile of data the data buf-
fer should typically be at least as large as the value returned by TIFFTileSize.
RETURN VALUES
The actual number of bytes of data that were placed in buf is returned; TIFFReadEncodedTile returns -1 if an error was encountered.
DIAGNOSTICS
All error messages are directed to the TIFFError(3TIFF) routine.
