    <p>I need to resize image from its natural size to fit the screen the same way as Chrome does with opened images in it, I wrote a <code>rescale(</code>) function for this purpose (below).</p> <p>It works mostly fine but for big landscape-oriented images (example where both width and height both exceed screen after resizing with my function <a href="http://imageontime.com/upload/big/2013/07/20/51ea60b522bba.jpg" rel="nofollow">http://imageontime.com/upload/big/2013/07/20/51ea60b522bba.jpg</a> ) fullscreened image still exceeds screen by few lines at height (and rarely at width), so i wanted to ask if there is a better rescale javascript function out there or if here are any chromium source adepts who could look into chromiums source code to get the image resizing function from it so I could port it into javascript?</p> <p>Here's the code:</p> <pre><code>function setautow() { img.style.width = 'auto'; img.style.removeProperty("height"); if (document.documentElement.clientHeight == 0) // Firefox again... { img.height = window.innerHeight; } else { img.height = document.documentElement.clientHeight; } } function setautoh() { img.style.height = 'auto'; img.style.removeProperty("width"); if (document.documentElement.clientWidth == 0) // FF { img.width = window.innerWidth; } else { img.width = document.documentElement.clientWidth; } } function shrink(a) { if (a) { if (img.width != document.documentElement.clientWidth) { setautoh(); } } else { if (img.height != document.documentElement.clientHeight) { setautow(); } } } var rescaled = false; function rescale() { if (rescaled) { rescaled = false; img.height = img.naturalHeight; img.width = img.naturalWidth; img.style.removeProperty("height"); img.style.removeProperty("width"); } else { rescaled = true; if (img.naturalWidth &gt; img.naturalHeight) { setautoh(); setTimeout(function () { shrink(true); }, 0); } else { setautow(); setTimeout(function () { shrink(false); }, 0); } } } </code></pre>

    1. COEdited question, was doubting how to formulate that part. P.S. backticks don't work with such big code so I'll need lots of em or wouid have to 4space every line... So I just posted pastebin, it won't expire there don't worry, it's set to Never expire.

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.

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