Page 6 - PDF Generation With PHP Lines aren't the only thing you can draw - circles and rectangles also figure prominently on the menu. Take a look at the following example, which demonstrates. Here's the output: In this case, the pdf_rect() function has been used to draw a rectangle, given the coordinates of the lower left corner and the height and width. This rectangle has then been filled and outlined in two different colours, via the pdf_fill_stroke() function. pdf_setcolor($pdf, "fill", "rgb", 1, 1, 0); pdf_setcolor($pdf, "stroke", "rgb", 0, 0, 0); pdf_rect($pdf, 50, 500, 200, 300); pdf_fill_stroke($pdf); Circles are handled by the pdf_circle() function, which accepts three arguments: the X and Y coordinates of the circle center, and the length of the circle radius.

I will soon be outlining a detailed How-To just for spam. For the sake of clarity, I’ll be using “tobias.local” for my domain, and 123.123.123.123 for my IP address. …which are excellent, but a little different from what I’ll be doing here. I’m running on Sarge (Testing), so if you’re running Stable you’ll need to change some of your apt settings. and to /etc/apt/apt.conf: APT::Default-Release “stable”; APT::Cache-Limit 12582912; What this does is say “pin all packages at stable” Now repeat for /etc/skel. –> quit

Looking for freelancers I’m always on the look out for talented freelancers and, at the moment, I’ve got a particular need for designers & developers who are strong with WordPress (not immediate start stuff, just looking forward to next few months). Update: I’m also very keen to hear from the following people: strong, hard core, JS people (especially ember.js, node etc)IOS & Android app developers (both native & cross platform)Strong, general PHP (must have linux skills)project managers Note: please do not respond if you’re an agency. Role 1: Designer/HTML & CSS builder (+ WordPress) You’ll design and build websites & have history in doing so & a visible portfolio. I’d expect you to know a bit about jQuery (e.g. getting plugins workings) but not be a PHP expert or be a hardcore WordPress serverside expert (that’s role 2). Ideally you’ll know the basics about GIT and/or SVN (or are prepared to learn). Role 2: PHP developer (+ WordPress) You’re almost certainly not a designer but a hard core PHP coder. Freelancer?
