With the release of ProcessingJS it has become relatively easy to share your Processing programs on the web. The process works by compiling your Java code into JavaScript and then rendering the output using the HTML5 canvas element in the browser. The result is a web-based version of your sketch that is rendered without any plugins -- this means that your program will be accessible in any modern browser, including on mobile devices!

Before you start: Preparing your source code

Processing definition

If you've been working in Eclipse you have to make some minor adjustments to your Processing source code before you can render it on the web. Here's how to get started:

  • Create a new text file to hold your source code. Use any text editor (TextEdit on the Mac or Notepad on the PC).
  • Copy the code from your main class into this new source code file. Remove any import statements (Processing on the web won't work with any imported Java libraries). Also remove the class block - your code should be 'loose' and not contained with a block of execution
  • If you have multiple classes / files you can simply paste them into your newly created text file AFTER your main class, making sure not to mess up the braces for each class. If you have any classes that were organized into packages you should place them into this file as well. Change all 'public class' declarations to just 'class' and remove any import statements.
  • Save your file as plain text using the 'pde' file extension - i.e. .'myProgram.pde'

Now we can embed the code into a web page by doing the following:

Processing is an electronic sketchbook for developing ideas. It is a context for learning fundamentals of computer programming within the context of the electronic arts. It may take up to 4 weeks from the day you apply until your application status is “In Process.” During these 4 weeks, your application is delivered to a mail facility, your payment is processed, and your application is scanned and sent to us. These processing times indicate the average processing time for all prevailing wage applications for the most recent month. Actual processing times for each employer’s prevailing wage application may vary from the average depending on material facts and individual circumstances of the case.

Hardcopy Bill/Attachments Processing To avoid processing delays, OWCP is asking medical providers to submit medical bills/attachments electronically. Hardcopy bills and documents require a team of individuals to physically report to our mailroom facility to open, scan, and transmit these documents to our bill processor for payment.

  • Create a new HTML document
  • Place a copy of your Processing PDE file into the same folder as your HTML document. In this example our PDE file is named 'myProgram.pde'
  • Place a copy of the processing.js library file into the same folder as your HTML document. You can get a copy of this file from the website
  • In the head of your document, place the following code to load in the processingjs library:
  • In the body of your document create a canvas tag that references your PDE file, like this:

Uscis Processing Times

If you are planning on using external artwork you will need to upload your assets to your website along with your PDE source code file. Then add the following 'preloader' directive at the top of your sketch as a comment - this will tell ProcessingJS to have the files available when your sketch begins running.
