TIFFReadEncodedStrip(3T) Image Format Library C++ Reference Manual
TIFFReadEncodedStrip - read and decode a strip of data from an open TIFF
tsize_t TIFFReadEncodedStrip(TIFF* tif, tstrip_t strip, tdata_t buf,
Read the specified strip of data and place up to size bytes of
decompressed information in the (user supplied) data buffer.
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
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,
The actual number of bytes of data that were placed in buf is returned;
TIFFReadEncodedStrip returns -1 if an error was encountered.
All error messages are directed to the TIFFError(3T) routine.
