These are the important configurations:</p> <pre class="prettyprint"><code> highlightbackground="your border color here" highlightcolor="your border color here" highlightthickness="the border width" bd= 0 </code></pre>

Revision 4. </p> <p>Frame with linear gradient using PIL. </p> <p>It's also possible to make the same trick using tkinter PhotoImage.</p> <p><a href="http://stackoverflow.com/questions/10417524/why-is-photoimage-put-slow" rel="nofollow">http://stackoverflow.com/questions/10417524/why-is-photoimage-put-slow</a></p> <p>But PIL is more efficient:</p> <p><a href="https://groups.google.com/forum/#%21topic/comp.lang.python/nQ6YO-dTz10" rel="nofollow">https://groups.google.com/forum/#!topic/comp.lang.python/nQ6YO-dTz10</a></p> <p>Possible values for <strong>orient</strong> are: <em>VERTICAL</em>, <em>HORIZONTAL</em>. If <strong>orient</strong> is "vertical", then width is mandatory. If <strong>orient</strong> is "horizontal", then height is mandatory. If <strong>steps</strong> is <em>None</em>, then the gradient is composed of adjacent lines.</p> <p>One possible practical application of gradient frames are tool bars. Gradient guives a visual clue of when an area starts and when an area finish. </p>

Revision 2. </p> <p>A script evaluating PSNR metric of two YUV420 frames <strong>usage: psnr.py filename1.yuv filename2.yuv frame_width frame_height</strong></p> <p>Alternatively if filename1 contains width and height in the form <strong>file-1200x1600.yuv</strong>, the script will extract width and height of a frame from the filename. Then usage even simplier: <strong>psnr.py filename1-1200x1600.yuv filename2.yuv</strong></p>
