NAME
TIFFReadEncodedStrip - read and decode a strip of data from an open
TIFF file
SYNOPSIS
#include <tiffio.h>
tmsize_t TIFFReadEncodedStrip(TIFF *tif, uint32_t strip, void *buf, tm-
size_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 re-
turned by TIFFStripSize(). If -1 is passed in the size parameter, the
whole strip will be read. You should be sure you have enough space al-
located 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 ma-
chine 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 TIFFErrorExtR() routine.
