TIFFReadEncodedStrip(3T)

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

SYNOPSIS
#include <tiffio.h>
int TIFFReadEncodedStrip(TIFF* tif, u_int strip, u_char* buf, u_int size)

DESCRIPTION
Read the specified strip of data and place size bytes of decompressed information in the (user supplied) data buffer. The actual number of bytes of data that were placed in buf is returned; TIFFReadEncodedStrip() returns -1 if an error was encountered.

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().

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 always done if the FillOrder tag is opposite to the native machine bit order. Byte swapping of 16- and 32-bit samples is automatically done when Compression=1 (``no compression''), but otherwise is left to the decompression algorithms (which should generate decompressed data in the native byte ordering of the machine).

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