im_setupout - set up an image descriptor for WIO output
<h2><a name='sect1' href='#toc1'>Synopsis</a></h2>
<b>#include
<vips/vips.h></b>
<p> <b>int im_setupout(image)</b> <br>
<b>IMAGE *image;</b>
<h2><a name='sect2' href='#toc2'>Description</a></h2>
<a href='im_setupout.3.html'><b>im_setupout(3)</b></a>
makes a descriptor ready for WIO
writing. If the descriptor is a memory buffer, enough memory is allocated
to be able to hold all of the pels of the image. If the descriptor is an
output file, then the header is written to disc.
<p> Typically, for WIO, you
<p>should have
<p> int<br>
im_wombat( in, out )<br>
IMAGE *in, *out;<br>
{<br>
if( im_iocheck( in, out ) )<br>
return( -1 );<br>
<p> ... check parameters, check image descriptors <br>
... for type-compatibility, etc. etc.<br>
<p> if( im_cp_desc( out, in ) )<br>
return( -1 );<br>
<p> ... set fields in out for the type of image you<br>
... wish to write<br>
<p> if( im_setupout( out ) )<br>
return( -1 );<br>
<p> ... process from input to output, reading from in->data<br>
<tt> </tt> <tt> </tt> ... and writing to out with <a href='im_writeline.3.html'>im_writeline(3)</a>
<br>
<p> return( 0 );<br>
}<br>
<h2><a name='sect3' href='#toc3'>Return Value</a></h2>
