TIFFReadEncodedStrip(3TIFF)											       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 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(3TIFF).  If the -1 passed in size parameter, the whole strip will be read. You should be sure you have enough space allo-
       cated 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.
