TIFFReadEncodedStrip(3tiff)

NAME

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

SYNOPSIS

       #include <tiffio.h>

       tsize_t TIFFReadEncodedStrip(TIFF *tif, tstrip_t  strip,  tdata_t  buf,
       tsize_t size)

DESCRIPTION

       Read  the  specified strip of data and place up to size bytes of decom-
       pressed 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(3TIFF).  If the -1 passed in size  parameter,  the  whole
       strip  will be read. You should be sure you have enough space allocated
       for the buffer.

       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;
       TIFFReadEncodedStrip returns -1 if an error was encountered.

DIAGNOSTICS

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