BIT 1. 01 Bill Gates touched my Mac Book Pro. In the past few weeks, Ive been itching to learn some new stuff. Those who know me even just a little bit know that new stuff is generally going include new ways of creating graphics andor animations. And so it does this time. Ive been creating graphics in HTML5 Canvas for quite a few years now, and thats cool.

For greater convenience, you can use the allinone installer which handles. But there are a few pain points with its workflow 1. It sometimes seems silly to pipe everything through the browser all the time. Id like to just be able to run a program and have it create a file and display that file. Running in the browser via the file system introduces various security issues, so you need to run some kind of local server, and even then you run into issues with saving files to disk automatically, so you need to right click and save or set up some kind of button to save an image. At work, Im using React with Webpack and Babel, so I get to use the latest and greatest ECMAScript with classes and all the other syntactic sugar. Its really nice, but setting all of that up is not trivial. For a one time large project, its not a huge deal to spend some time on creating all that config. How To Install Pycairo Python' title='How To Install Pycairo Python' />But if youre going to be doing random experiments all the time, its a ton of overhead. I get stuck with whatever the current browsers implement. So Ive been looking for some other language drawing api I could learn. After a short amount of searching, I came across Cairo Graphics. Its a 2. D graphics library, written in C, but has bindings for several other languages. Well, that sounds pretty cool. Looking over the tutorials and api documents https cairographics. I see that you create a surface, then get a context from that surface, then call various commands on the context such as moveto and lineto, and then follow up with stroke andor fill. Well that sounds awfully familiar. In fact, Im going to guess that HTML5s Canvas is either backed up by Cairo at some level, or is at the very least inspired by Cairos api. At any rate, it sounded worth looking into. I wasnt about to dive into C programming, but as I mentioned, there are bindings for several other languages. The first I tried was Python, and that worked great. Ill probably do another tutorial on py. Cairo at some point, but I wanted to take it a little further and really dive into something new. Ive had my eye on a couple of languages Rust and Go. Both have Cairo bindings, so I flipped a coin and decided to try out Rust. USRust is a pretty interesting programming language. How To Install Pycairo Python' title='How To Install Pycairo Python' />Its built around speed and safety preventing you from doing bad things. As such, it has some programming paradigms that seem really strange at first. But theres a lot of logic behind those decisions. Im not going to do a Rust tutorial here. But the documentation on how to learn the language is some of the best learning material Ive seen on any site for any language or system. Just start reading The Book https doc. Im going through the Second edition, which is still listed as under construction, but I havent run into any flaws or incompleteness as of yet. What I do want to cover in this tutorial is using Cairo in Rust. Theres a lot resources on how to use Cairo, lots of stuff on how to use Rust. But the center part of the Venn diagram is rather thin. So, heres what you need to do 1. Install Rust and learn how to program in it. At least the basics. I had to read maybe 13 of The Book before I felt I was ready to start trying to pull in the Cairo bindings and create some graphics. Install Cairo. This is the C library itself. It needs to be on your system so that the Rust bindings for Cairo have something to bind to. Im on Ubuntu, so this was really easy, just sudo apt install libcairo. On Mac. OS, it seems youre supposed to use Mac. Ports, which Im not really familiar with, or fink, which Ive never heard of. On Windows, it looks like you just have to add a few dlls to your path. OK, well carry on, assuming you got Cairo installed. Create a project and set up the dependencies. Again, this is not a Rust tutorial, but to create a Rust project, you can use cargo new. This creates a new project named cairostuff, which will be a binary executable, bin as opposed to a library project. Youll see a new folder with the project name. Inside that will be a src folder and a. It also sets up the project to use git by default, so you get a. The. toml file is the project configuration file. It should look something like this packagename cairostuffversion 0. Your Name lt youdomain. The authors data is taken from your. We need to add our Cairo binding as dependencies for this project. To do that, we list them under dependencies. Well need two packages or crates as they are called in Rust. Well need the png crate so we can save images, and the cairo rs crate which contains the actual Cairo bindings. We also need to add png as a feature to cairo rs, so that cairo rs itself knows how to save pngs. Whenever youre doing dependency configuration in any language, its important to have a way to know what versions of different dependencies are available. In Rust, you can go to https crates. The first match tells us that we want version 0. And for cairo rs, its 0. Note, these will definitely and continuously change, so actually go to the site and check the numbers. For png, we can just add a line in the dependencies section that saysdependenciespng 0. Simple. But the cairo rs line is a bit more complicated because we need to pass png into it as a feature. So we saydependenciespng 0. Again, read The Book to fully understand all the syntax here. But this will get you up and running. Now, if you look at the main source file in the project, its srcmain. Hello, world If youve done any kind of programming, all that should be pretty self explanatory. You have a function called main. Rust follows the pattern of many other languages where main is the function that is called when the program is executed. In main, we call println, passing a string. Tna Impact Wrestling Pc Game. Other than the exclamation point there, it should be straightforward. The indicates that println is implemented as a macro, not a function, but whatever. At this point you can call cargo run from the main project directory. This will satisfy all your dependencies, build the executable, and run it. It should print out the message Hello, world. Great It probably took a while to download everything it needed. But if you run it again, it should complete almost instantly. If you now look in your project folder, youll see you have a Cargo. The target is where your final executable and all the build artifacts are. The lock file lists all the other dependencies that got pulled in when you added png and cairo rs. Driver Bluetooth Wireless Networking 802.11 B/G/N. For me, this file wound up at 1. Lets Draw Some Stuff. Now that weve set things up, lets draw something. Here are the basic steps 1. Create an image surface. Create a 2. D drawing context that references that surface. Draw things. 4. Create a file. Write the surface to the file as a png. For most of your projects, steps 1, 2, 4 and 5 are going to be boilerplate. The meat is going to be step 3 where you draw the actual content you want to draw. First, were going to need to import the cairo rs bindings. Thats an external crate that we downloaded in our dependencies. So up at the top of the file we sayextern crate cairo Note that although the crate name was cairo rs, we just link to it as cairo.
