TIFFReadEncodedStrip(3T)             Image Format Library C++ Reference Manual



NAME
     TIFFReadEncodedStrip - read and decode a strip of data from an open TIFF
     file

SYNOPSIS
     #include <tiffio.h>
     tsizet TIFFReadEncodedStrip(TIFF* tif, tstript strip, tdatat buf,
     tsizet size)

DESCRIPTION
     Read the specified strip of data and place up to size bytes of
     decompressed information in the (user supplied) data buffer.

NOTES
     The value of strip is a ``raw strip number.''  That is, the caller must
     take into account whether or not the data are organized in separate
     planes (PlanarConfiguration=2).  To read a full strip of data the data
     buffer should typically be at least as large as the number returned by
     TIFFStripSize(3T).

     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 automatically
     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;
     TIFFReadEncodedStrip returns -1 if an error was encountered.

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