TIFFReadEncodedStrip - read and decode a strip of data from an open
tsize_t TIFFReadEncodedStrip(TIFF *tif, tstrip_t
strip, tdata_t buf, tsize_t
Read the specified strip of data and place up to size
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
=2). To read a full strip of data the data buffer
should typically be at least as large as the number returned by
(3TIFF). If the -1 passed in size
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 automatically byte-swapped if
the file was written with a byte order opposite to the native machine byte
The actual number of bytes of data that were placed in buf
returns -1 if an error was encountered.
All error messages are directed to the TIFFError
