Good night,<div><br></div><div>I am currently starting to develop with olena/milena and I was following the tutorial when I found something that puzzled me:</div><div><br></div><blockquote style="margin: 0 0 0 40px; border: none; padding: 0px;">

<div><div> 63     image2d&lt;value::rgb8&gt; lena;</div></div><div><div> 64     io::ppm::load(lena, MLN_IMG_DIR &quot;/small.ppm&quot;);</div></div><div><div> 65 </div></div><div><div> 66     std::cout &lt;&lt; geom::min_row(lena) &lt;&lt; &#39; &#39; &lt;&lt; geom::max_row(lena) &lt;&lt; &#39;\n&#39;;</div>

</div><div><div> 67     std::cout &lt;&lt; geom::min_col(lena) &lt;&lt; &#39; &#39; &lt;&lt; geom::max_col(lena) &lt;&lt; &#39;\n&#39;;</div></div><div><div> 68 </div></div><div><div> 69     for (def::coord row = geom::min_row(lena); row &lt; geom::max_row(lena); ++row)</div>

</div><div><div> 70         for (def::coord col = geom::min_row(lena); col &lt; geom::max_col(lena); ++col)</div></div><div><div> 71             if (((row + col) % 2) == 0)</div></div><div><div> 72                 opt::at(lena, row, col) = literal::green;</div>

</div><div><div> 73 </div></div><div><div> 74     io::ppm::save(lena, &quot;./lena_chess.ppm&quot;);</div></div></blockquote><div><div><br></div><div>The definition of geom::min/max_row/col its that it gives you the image limits, so I should get lena&#39;s image in a chess pattern. </div>

<div>Strangely as it may look, it happens to not fill the right and bottom edges as you can see in the picture:</div><div><br></div><div><img src="cid:ii_133f1f73e1f205a1" alt="image.png" title="image.png"><br></div><div>

<br></div><div>I think there is something wrong in the tutorial as the loop should have as upper limit<font class="Apple-style-span" color="#000099"> row/col <b>&lt;=</b> geom::max_row/col</font> instead of <b>=</b></div>

<div><br></div><div><a href="http://www.lrde.epita.fr/dload/olena/2.0/doc/milena/user-refman-html/d3/dfe/a00025.html">http://www.lrde.epita.fr/dload/olena/2.0/doc/milena/user-refman-html/d3/dfe/a00025.html</a></div><div>
<br>
</div><div>The thing is that in all the tutorials the limit is set as =, so it is either a bug in milena&#39;s function or in the tutorial (or in my computer ;) )</div><div><br></div><div>Best regards</div><br clear="all">
