For the most part, this isn’t much of a problem, as a lot of the stuff I work on is revisited later and is viewable as a result. This isn’t the case with everything however. There are several pieces of code that I have produced and I’ve meant to revisit at points, but simply never have have the time to trawl through everything I’ve put up here to re-visit them.

Something Old & Something New

Today sees a new section being kinda added here on my portfolio. It’s currently not listed anywhere in the navigation, whilst I try to determine how best to add it in, but people have been able to visit some of the content it provides previously. So what have I added? I’ve shifted my demos from a folder of my site and integrated them much better into my site’s design, adding them as a custom post type, which affords me a better control over things. This means that people can check out some of the code I’ve produced sporadically without having to go hunting it down, much like visitors to my site don’t have to hunt down my Portfolio.

I’ll be playing about with how best to add this new section into my site, but for those of you that are reading about it here, you can view my my code demonstrations here. I should point out that this new section also ties in with my Coding posts on my blog. The demos are to view the results, the posts look at things in a bit more depth. I’ll also be working to connect these two areas together a bit better in the near future.

Hope you like what you find in the new section, I hope to be adding to it a bit more in the near future, as well as updating the Code section to reflect all the new additions. Enjoy!

How?

PHP has a great deal of functionality when it comes to generating content to be displayed on a website. One thing it can’t do, by itself, is produce images. To do this it needs a little bit of help, in the form of the GD Library, which enables image generation with PHP. Two files were needed to generate the example. The first was the file that loops through all of the required number of images to get them displayed, and the second generating the images, which looks something like this:

<?php
$w = $_GET['w'];
$h = $_GET['h'];
$r = rand(0,255);
$g = rand(0,255);
$b = rand(0,255);
header("Content-type: image/png");
$im = @imagecreate($w, $h)
    or die('Cannot Initialize new GD image stream');
$background_color = imagecolorallocate($im, $r, $g, $b);
imagepng($im);
imagedestroy($im);
?>

This allows for easy image genration, passing in variables for the required width and height. Click the link below to see an example of it in action.

Demo

It will also allow for visitors to my site to see a bit more about what I do, the thought process I take when doing it, and also most importantly, the why I do it. I’ll be looking over the various demos I have uploaded already over the next few days, so expect there to be new bits and pieces popping up here shortly.
