.SH NAME
|
|
|
|
|
TIFFReadEncodedStrip \- read and decode a strip of data from an open
|
|
|
|
|
.SM TIFF
|
|
|
|
|
file
|
|
|
|
|

|
|

|
|
.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
|
2005-11-02 06:07:18 -05:00
|
|
|
.BR TIFFStripSize (3TIFF).
|
2004-11-11 09:39:16 -05:00
|
|
|
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.
|
|
|
|
|
