Rect r is clipped against the edges of the image. im_smear() is not very useful. <p> Both these functions are ‘in place,’ that is, they write directly to the output image! Be very careful, you can destroy data. <h2><a name='sect3' href='#toc3'>Return Value</a></h2> All functions return 0 on success and -1 on error. <h2><a name='sect4' href='#toc4'>See Also</a></h2> <a href='im_insertplace.3.html'>im_insertplace(3)</a> , <a href='im_readpoint.3.html'>im_readpoint(3)</a> . <h2><a name='sect5' href='#toc5'>Copyright</a></h2> <br> National Gallery, 1992 <h2><a name='sect6' href='#toc6'>Author</a></h2> J.
