    <p>It's possible using canvas element. Get pixel data of image using <code>getImageData</code> method of canvas and check rgb value. To use <code>getImageData</code> you need to put your script file and image on same domain because of cross domain issue. In this case, the divider is not to be visible on #00ff00.</p> <p><a href="http://edwardrockhands.com/test/triforce.html" rel="nofollow">Sample</a></p> <p>HTML:</p> <pre><code>&lt;canvas id="canvas"&gt;&lt;/canvas&gt; </code></pre> <p>Javascript:</p> <pre><code>$(document).ready(function(){ var canvas=document.getElementById("canvas"); var ctx=canvas.getContext("2d"); var image=document.createElement("img"); image.onload=function(){ canvas.width = image.width; canvas.height = image.height; ctx.fillStyle="#00ff00"; ctx.fillRect(0,0,canvas.width,canvas.width); ctx.drawImage(image,0,0); init(); } image.src="Triforce.png"; function init(){ var imageData = ctx.getImageData(0, 0, image.width, image.height); var data = imageData.data; canvas.addEventListener('mousemove', function(evt) { var mousePos = getMousePos(canvas, evt); var x = mousePos.x; var y = mousePos.y; ctx.clearRect(0,0,canvas.width,canvas.height); ctx.fillStyle="#00ff00"; ctx.fillRect(0,0,canvas.width,canvas.width); ctx.drawImage(image,0,0); ctx.fillRect(x, 0, canvas.width,canvas.height); ctx.fillStyle="#0000ff"; for(var i=x;i&lt;x+10;i++){ for(var j=0;j&lt;image.height;j++){ var red = data[((image.width * j) + i) * 4]; var green = data[((image.width * j) + i) * 4 + 1]; var blue = data[((image.width * j) + i) * 4 + 2]; var alpha = data[((image.width * j) + i) * 4 + 3]; if(!(red==0 &amp;&amp; green==255 &amp;&amp; blue==0)){ ctx.fillRect(i,j,1,1); } } } }, false); } function getMousePos(canvas, evt) { var rect = canvas.getBoundingClientRect(); return { x: evt.clientX - rect.left, y: evt.clientY - rect.top }; } }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
