<div class="markdown level1 summary"><p>Returns the vertical coordinate of the image origin, the top-left
corner, in the canvas system, on the reference grid at the specified
resolution level.</p>
<pre><code>       &lt;p&gt;Note: Image resolution level indexes may differ from tile-component
       resolution index. They are indeed indexed starting from the lowest
       number of decomposition levels of each component of each tile.&lt;/p&gt;&lt;p&gt;Example: For an image (1 tile) with 2 components (component 0 having
       2 decomposition levels and component 1 having 3 decomposition levels),
       the first (tile-) component has 3 resolution levels and the second one
       has 4 resolution levels, whereas the image has only 3 resolution levels
       available.&lt;/p&gt;
