<h2>Hey man, Free-base64 is cool with this FileMaker Pro 13 Tip-n-Trick of Creating a Progress Status Bar</h2>

<p>&nbsp;<br />Or for those who are true nerdy geeks -</p>

<h2>All your base64 are belong to us, But We’ll Share this FileMaker Pro 13 Tip-n-Trick of Creating a Progress Status Bar</h2>

<p>&nbsp;</p>

<h3><em><b>Andy Persons shares his first </b><b>FileMaker Pro 13 Tip-n-Trick that demonstrates ProgressBar(),</b> a custom function that provides a simple and lightweight progress status bar.</em></h3>

<h3>What Got Me Thinking</h3>

<p>When I saw the Base64Decode function in the newly released FileMaker 13, my first thought was “why, you could theoretically calculate any image you want!” My second thought was: “would the complexity be worth it?” So, I decided to start with something simple: a 1 by 100-pixel graphic to display a progress bar. First, I tried creating .png images of various sizes, encoding them using Base64Encode() and comparing what changed. No go. I couldn’t discern any consistent patterns.</p>

<p>Next, I tried the same process using .bmp files. Better, but the patterns were still inconsistent.</p>

<p>Finally, I decided I needed to rethink my approach. I researched base 64 a bit more and realized that the patterns weren’t consistent because it concatenates all bits from the original and encodes them in 6-bit chunks. The best approach would be to build the bitmap from the ground up, if feasible.</p>

<p>So, I looked up the .bmp format on Wikipedia, built a basic bitmap file in hex, converted it to base 64 and created a custom function that replaces the color pixel placeholders with the specified colors! Easy as pie!</p>

<p>I hope you find the accompanying demo file useful. Merry Christmas!</p>

<h3><b>How It Works</b></h3>

<p>This technique makes use of FileMaker Pro 13′s new Base64Decode() function to convert text into an image. The ProgressBar() custom function includes a pre-built 1 x 100-pixel bmp base image and inserts the foreground or background pixels based on the “progress” parameter.</p>

<p>The resulting container is then set to enlarge or reduce without maintaining proportions and the padding is set to zero to ensure the graphic fills it completely.</p>
