Applications need never use these routines; they are provided only for ``intelligent clients'' that wish to optimize memory usage and/or eliminate potential copy operations that can occur when working with images that have data stored without compression. <P> <I>TIFFReadBufferSetup</I> sets up the data buffer used to read raw (encoded) data from a file. If the specified pointer is <FONT SIZE="-1">NULL</FONT> (zero), then a buffer of the appropriate size is allocated. Otherwise the caller must guarantee that the buffer is large enough to hold any individual strip of raw data. <I>TIFFReadBufferSetup</I> returns a non-zero value if the setup was successful and zero otherwise. <P> <I>TIFFWriteBufferSetup</I> sets up the data buffer used to write raw (encoded) data to a file. If the specified <I>size</I> is -1 then the buffer size is selected to hold a complete tile or strip, or at least 8 kilobytes, whichever is greater. If the specified <I>buffer</I> is <FONT SIZE="-1">NULL</FONT> (zero), then a buffer of the appropriate size is dynamically allocated. <I>TIFFWriteBufferSetup</I> returns a non-zero value if the setup was successful and zero otherwise. <A NAME="lbAE"> </A> <H2>DIAGNOSTICS</H2> <B>%s: No space for data buffer at scanline %ld</B>. <I>TIFFReadBufferSetup</I> was unable to dynamically allocate space for a data buffer. <P> <B>%s: No space for output buffer</B>. <I>TIFFWriteBufferSetup</I> was unable to dynamically allocate space for a data buffer. <A NAME="lbAF"> </A> <H2>SEE ALSO</H2> <I><A HREF="libtiff.3t.html">libtiff</A></I>(3T) <HR> <A NAME="index"> </A><H2>Index</H2> <DL> <DT><A HREF="#lbAB">NAME</A><DD> <DT><A HREF="#lbAC">SYNOPSIS</A><DD> <DT><A HREF="#lbAD">DESCRIPTION</A><DD> <DT><A HREF="#lbAE">DIAGNOSTICS</A><DD> <DT><A HREF="#lbAF">SEE ALSO</A><DD> </DL> <HR> This document was created by <A HREF="index.html">man2html</A>, using the manual pages.<BR> Time: 01:31:39 GMT, November 23, 1999 </BODY> </HTML>
