.TH TIFFReadEncodedStrip 3TIFF "October 15, 1995" "libtiff"

.SH NAME

TIFFReadEncodedStrip \- read and decode a strip of data from an open

.SM TIFF

file

.SH SYNOPSIS

.B "#include <tiffio.h>"

.sp

.BI "tsize_t TIFFReadEncodedStrip(TIFF *" tif ", tstrip_t " strip ", tdata_t " buf ", tsize_t " size ")"

.SH DESCRIPTION

Read the specified strip of data and place up to

.I size

bytes of decompressed information in the (user supplied) data buffer.

.SH NOTES

The value of

.I strip

is a ``raw strip number.''

That is, the caller must take into account whether or not the data are

organized in separate planes (\c

.IR PlanarConfiguration =2).

To read a full strip of data the data buffer should typically be at least as

large as the number returned by

.BR TIFFStripSize (3TIFF).

If the -1 passed in

.I size

parameter, the whole strip will be read. You should be sure you have enough

space allocated for the buffer.

.PP

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

.I 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,

.SH "RETURN VALUES"

The actual number of bytes of data that were placed in

.I buf

is returned;

.IR TIFFReadEncodedStrip

returns \-1 if an error was encountered.

.SH DIAGNOSTICS

All error messages are directed to the

.BR TIFFError (3TIFF)

routine.
