Welcome to Processing! Start by visiting http://processing.org/download and selecting the Mac, Windows, or Linux version, depending on what machine you have. Installation on each machine is straightforward:
- On Windows, you'll have a .zip file. Double-click it, and drag the folder inside to a location on your hard disk. It could be Program Files or simply the desktop, but the important thing is for the processing folder to be pulled out of that .zip file. Then double-click processing.exe to start.
- The Mac OS X version is also a .zip file. Double-click it and drag the Processing icon to the Applications folder. If you're using someone else's machine and can't modify the Applications folder, just drag the application to the desktop. Then double-click the Processing icon to start.
- The Linux version is a .tar.gz file, which should be familiar to most Linux users. Download the file to your home directory, then open a terminal window, and type:
tar xvfz processing-xxxx.tgz
(Replace xxxx with the rest of the file's name, which is the version number.) This will create a folder named processing-2.0 or something similar. Then change to that directory:
cd processing-xxxx
and run it:
./processing
With any luck, the main Processing window will now be visible. Everyone's setup is different, so if the program didn't start, or you're otherwise stuck, visit the troubleshooting page for possible solutions.

The Processing Development Environment.
Your First Program
You're now running the Processing Development Environment (or PDE). There's not much to it; the large area is the Text Editor, and there's a row of buttons across the top; this is the toolbar. Below the editor is the Message Area, and below that is the Console. The Message Area is used for one line messages, and the Console is used for more technical details.
In the editor, type the following:
This line of code means 'draw an ellipse, with the center 50 pixels over from the left and 50 pixels down from the top, with a width and height of 80 pixels.' Click the Run button the (triangle button in the Toolbar).
If you've typed everything correctly, you'll see a circle on your screen. If you didn't type it correctly, the Message Area will turn red and complain about an error. If this happens, make sure that you've copied the example code exactly: the numbers should be contained within parentheses and have commas between each of them, and the line should end with a semicolon.
One of the most difficult things about getting started with programming is that you have to be very specific about the syntax. The Processing software isn't always smart enough to know what you mean, and can be quite fussy about the placement of punctuation. You'll get used to it with a little practice.
Next, we'll skip ahead to a sketch that's a little more exciting. Delete the text from the last example, and try this:
This program creates a window that is 480 pixels wide and 120 pixels high, and then starts drawing white circles at the position of the mouse. When a mouse button is pressed, the circle color changes to black. We'll explain more about the elements of this program in detail later. For now, run the code, move the mouse, and click to see what it does. While the sketch is running, the Run button will change to a square “stop” icon, which you can click to halt the sketch.
Show
How To Launch Screenhero App From Zip File Mac 2019
If you don’t want to use the buttons, you can always use the Sketch menu, which reveals the shortcut Ctrl-R (or Cmd-R on the Mac) for Run. The Present option clears the rest of the screen when the program is run to present the sketch all by itself. You can also use Present from the Toolbar by holding down the Shift key as you click the Run button.
Save and New
The next command that’s important is Save. You can find it under the File menu. By default, your programs are saved to the 'sketchbook,' which is a folder that collects your programs for easy access. Select the Sketchbook option in the File menu to bring up a list of all the sketches in your sketchbook.
It’s always a good idea to save your sketches often. As you try different things, keep saving with different names, so that you can always go back to an earlier version. This is especially helpful if—no, when—something breaks. You can also see where the sketch is located on your computer with the Show Sketch Folder command under the Sketch menu.
You can create a new sketch by selecting the New option from the File menu. This will create a new sketch in its own window
Share
Processing sketches are made to be shared. The Export Application option in the File menu will bundle your code into a single folder. Export Application creates an application for your choice of Mac, Windows, and/or Linux. This is an easy way to make self-contained, double-clickable versions of your projects that can run full screen or in a window.
The application folders are erased and re-created each time you use the Export Application command, so be sure to move the folder elsewhere if you do not want it to be erased with the next export.
Examples and Reference
Learning how to program involves exploring lots of code: running, altering, breaking, and enhancing it until you have reshaped it into something new. With this in mind, the Processing software download includes dozens of examples that demonstrate different features of the software.
To open an example, select Examples from the File menu and double-click an example's name to open it. The examples are grouped into categories based on their function, such as Form, Motion, and Image. Find an interesting topic in the list and try an example.
When looking at code in the editor, you'll see that functions like ellipse() and fill() have a different color from the rest of the text. If you see a function that you’re unfamiliar with, select the text, and then click 'Find in Reference' from the Help menu. You can also right-click the text (or Ctrl-click on a Mac) and choose 'Find in Reference' from the menu that appears. This will open a web browser and show the reference for that function. In addition, you can view the full documentation for the software by selecting Reference from the Help menu.
The Processing Reference explains every code element with a description and examples. The Reference programs are much shorter (usually four or five lines) and easier to follow than the longer code found in the Examples folder. We recommend keeping the Reference open while you’re reading this book and while you’re programming. It can be navigated by topic or alphabetically; sometimes it’s fastest to do a text search within your browser window.
The Reference was written with the beginner in mind; we hope that we’ve made it clear and understandable. We’re grateful to the many people who’ve spotted errors over the years and reported them. If you think you can improve a reference entry or you find a mistake, please let us know by clicking the link at the top of each reference page
Screenhero is now built into Slack
UPDATE (Dec. 1st, 2017): We’re in the process of closing down Screenhero, and it will be fully shut down by 11am PST on Monday, Dec. 4th. Please know that we’re listening closely to your feedback on screen sharing in Slack, and we’re doing everything we can to address your concerns. Our current priorities include making the experience faster, supporting the cmd/alt tab shortcut, and supporting remote copying and pasting. Please don’t hesitate to be in touch — you can reach out to us at [email protected].
Hello Screenhero users,
We’ve finally done it: Screenhero-style screen sharing is now in Slack!
Since Slack acquired Screenhero in 2015, we’ve been working to move screen sharing into Slack bit by bit, first with voice and video calling and then with presentational screen sharing.
As of today, Slack now supports interactive screen sharing as part of the native calls experience, which means that you can present your screen, co-edit documents, or troubleshoot in tandem right from any Slack video call.
How to use screen sharing in Slack
Before you begin, make sure you’re on a paid plan, using the latest version of Slack’s Windows desktop app or the direct download version of Slack’s Mac desktop app.
- Start a Slack call from any channel or conversation — you can click at the top of the screen, or type
/call
and hit enter. - Click the screen icon to share your screen with the other people on the call.
- Click to share control of your screen.
That’s it!
Is there anything new or different?
While Screenhero was designed for screen sharing between just two people, Slack Calls are built to support multi-party video calls, with video streams for each participant. This means that you can share control of your screen in Slack with up to 15 participants at once, a scale not previously possible with Screenhero.
There’s also a new option when you’re presenting your screen. Participants viewing your shared screen can temporarily draw over it — underlining, circling, or directing focus to a particular area that needs more attention.
What will happen to the Screenhero product?
As we announced in 2015, we will wind down the Screenhero product after moving all of its features into Slack. Screenhero as a stand-alone app will be closing its doors on December 1st, 2017, so you‘ll no longer be able to log in or use the product after that.
A final word of thanks
When we first started Screenhero, we were a small team with a vision for a more collaborative way for teams in different locations to work together. We never would’ve guessed that a few years later, our creation would reach the millions of people using Slack to work together every day.
Thank you to everyone in the Screenhero community, for believing in our product and supporting us along the way. You have changed our lives. For now, we say farewell, and we hope to see you in Slack.
— The Screenhero Team
Already a Screenhero user? Here’s how to invite others.
Even though new signups are closed while we concentrate our efforts on the integration with Slack, we want existing Screenhero users to have the same experience as before. Part of the Screenhero experience means inviting new users!
To invite someone, click the Add Contact button and follow the prompts:
Group Screen Sharing
On Friday, we launched our most exciting update yet, packed with features we hope you’ll love:
- Group screen sharing + voice: if you liked 2 mouse cursors, you’ll love 5 (for now, there are no limits to the number of participants)!
- When your connection drops, we automatically reconnect you
- You can now select a new screen to share without ending the session
- On Windows, Screenhero is far more stable, and Windows 8 is >2x faster than before
- Faster, globally-distributed servers, which means better performance for everyone, especially users outside the US.
Enjoy! :)
Screenhero 2.0 Pre-Launch
We’ve been hard at work on Screenhero v2.0 for many months now, and many of you have been amazing beta users, helping make it ready for primetime. As it happens, our computers decided today was primetime — and we inadvertently released v2.0 to all Mac users earlier this morning. We are very sorry if that update has affected you negatively — but we hope that with more information and hard work on our part, we can make this a net positive.
The good news is that Screenhero v2.0 contains one epic feature: multi-party screen sharing + multi-party voice calls! To use it, make sure everyone on your team is on v2.0, and then either click on each contact you want to start a screen share / call with, or start with one person and add every additional person as needed.
We’re going to write a bigger post on what’s included in v2.0 soon, but for now here are the updates from earlier on this morning:
Update (Feb 6, 1:38PM PST): All is well in the kingdom. The Mac release + dev branches have been updated to v2.0.0.1 (fixes the ‘can’t screen share’ bug too) — 'check for updates’ should now do the right thing, so you don’t need to re-download from the website anymore. Windows release/dev are also updated (v2.0.0.0). Whew! Sorry about that, everyone, but everything should be back to normal now (and with group screen sharing + calls, better than before).
Also, we will revisit our processes to try our best to make sure this never happens again.
Update (Feb 6, 1:05PM PST): The Mac release + dev branches have been updated to v2.0.0.1 (fixes the 'can’t screen share’ bug too) — 'check for updates’ should now do the right thing, so you don’t need to re-download from the website anymore. Windows release/dev are still pending (our update process hit a snag).
Update (Feb 6, 12:58PM PST): The Mac release branch has been updated, but both Mac dev and Windows release/dev are still pending (our update process hit a snag). Also, on Mac v2.0.0.0, there is still a bug where you cannot share your screen after one successful screen share. We are working on it. For now, the only workaround is to restart Screenhero for your next screen share.
Update (Feb 6, 12:21PM PST): The Mac release branch has been updated, while the dev branch is pending (10 mins away). If you urgently need Screenhero to work on a Mac, but were on the beta, download the binaries from https://screenhero.com/download.html, and all should be well.
Update (Feb 6, 12:01PM PST): We are aware of the bug with Mac screen sharing, and the update is going live imminently (by 12:25PM PST), as is the Windows update.
Screenhero joins Slack
Hello Screenhero users,
We have big, very happy news to share. Screenhero is joining Slack!
Slack is a product for team communication, and we’re excited to bring our unique combination of voice, video and screen sharing to the table. We’ve been using Slack for months within Screenhero, and we love it. If you haven’t heard of it yet, check it out (https://slack.com) — we’re confident you’ll love it just like we do. Slack and Screenhero are both changing the way teams work together, which is why joining forces made so much sense to us.
As part of the acquisition, many things are going to change, and many things are going to stay the same. On the whole, this is going to be an incredibly positive change for you, our users.
In brief:
- We will be migrating Screenhero’s features to Slack over the coming months
- During this time, current Screenhero and Slack customers can use Screenhero for free
- While we focus on the integration, new signups to Screenhero will be closed
- Once the integration is complete, Screenhero as a standalone service will be phased out
- The integrated Slack + Screenhero experience is going to be incredible. We’re positive you will love it.
That’s the high level overview. Here are some details that will give you a fuller picture of what to expect:
I’m an existing Screenhero user. What does this mean for me?
The team at Slack is excited about the product we’ve built and they’re excited to have you as a customer. We are collectively committed to making this acquisition a positive one for all of our customers — this includes you.
You can continue to use Screenhero as a standalone product for the time being, while we work on migrating its core functionality to Slack. At that time, we will offer you a migration path to using Slack, where you will enjoy awesome screen sharing with voice and video calls, and also the best team communication product known to mankind (in our humble opinion). So your experience of Screenhero will not change for the short term. And, though Screenhero will be phased out as a standalone product, you’ll be able to enjoy the same experience within Slack once we’re done, and we will be continuing to invest in new developments that will make it even better.
We will, of course, continue to support and fix any critical bugs in Screenhero until it is phased out, and may also push out some of our upcoming voice and video functionality to the app.
How much will this cost me?
Screenhero is now free for all existing users, while we migrate its functionality to Slack. If you’re a monthly subscriber, the last bill you received is your final bill — you won’t be charged again for Screenhero. If you’ve paid an annual subscription, your unused subscription will be refunded shortly (we’ll be in touch!).
Once we migrate to Slack, our current plan is to have 1:1 voice and video calls as part of Slack’s Lite plan, group voice and video on the Standard plan, and 1:1 and group screen sharing as either part of the Plus plan, or as an à la carte add-on to any paid plan. However, we are still thinking through the best approach, so this is tentative, and may change in time.
What about new users?
While we focus on migrating our functionality to Slack, new user signups will be closed. Existing Screenhero users can still invite new users through the Screenhero app — click the Add Contact button on the top right corner as before, and you can send invites out by writing in your contact’s email address. Also, just so that they can get a taste of what’s to come and kick the tires, current Slack customers can create Screenhero accounts (visit https://slack.com/screenhero if you’re a paid Slack user).
What will the Screenhero team be doing?
Over the coming months, we’re going to be working on bringing our unique flavor of voice, video, and screen sharing to Slack, to make the joint product the best of both worlds. Since Slack is on Mac and Windows (like Screenhero) as well as iOS, Android, and the web, this is a massive undertaking, but one that we’re excited to take on.
And that’s it.
But, if you are interested in hearing a little bit more about the story from our perspective, read on…
Thank you for all your support, suggestions, bug reports and love. We’re going to make sure every drop of that is going to make its way into Slack, and create something even more powerful. Dimethylglycine dmg.

The Screenhero Story
Even though we launched Screenhero two years ago, our story began almost 7 years ago. Our first company, iTeleport, was founded while I was a PhD student at Carnegie Mellon, working on voice interfaces for low-literate community health workers in rural Pakistan. iTeleport was an app that let you control your computer from your iPhone: a remote desktop app for iPhone (and eventually, iPad and Mac). The first version was released on the pre-App Store jailbreak ecosystem, back in 2008.
Fast forward four years: the team grew to four incredible people, who co-founded Screenhero to tackle the challenge of connecting people and making it possible to work together like you’re in the same room. In 2013, we raised $2.6M from an amazing group of investors, led by Jon Callaghan at True Ventures, and including amazing angels and institutions such as Elad Gil, Andreessen Horowitz, Y Combinator, Paul Buchheit, Alexis Ohanian, and Matt Mullenweg. We then spent more than a year perfecting our product based on feedback from an incredibly vocal group of passionate people — you, our users!
In August 2014, we started charging for Screenhero — by making Screenhero a profitable business, we felt we could best serve the needs of our customers for the long haul. It worked tremendously well, and we learned very quickly that our product had resonated so well with our customers that our finances were a solved problem.
Around this time, we took a step back to see where our future was headed, and where the industry was going. When we started Screenhero, we thought that the most important thing to get work done was to focus on the act of doing work — in applications on your desktop — and making that collaborative through immersive screen sharing. However, we learned that communication is a bigger challenge that underlies all collaboration, and that the right solution is to have a foundation based on communication — not just between you and your team members, but between you and your services as well. Leveraging voice, video and screen sharing on top of that would be the ideal solution, truly solving the problems customers actually have.
It turned out that Slack was already well on its way to solving the communication problem. We ourselves have been using Slack happily for months, and we’ve loved the product. Over the last few months, we’ve grown to love the team as well, and together we’ve realized that joining forces to create a unified product that contains the best of both worlds makes the most sense for our customers as well as for us.
We were under no pressure to sell our company: our financial prospects as an independent company were very bright, and we loved what we were working on. We decided to sell because we truly believed it was the best option for us, for Slack, and for our customers. We are excited to continue the work that we started at Screenhero. Unlike other acquisitions you may have heard of, we are committed to making our product’s core features live long and prosper.
We are phasing out the standalone Screenhero product because it’s a far better user experience to have its functionality deeply integrated inside Slack.

We want to do right by our customers, and that’s why we’re making sure that your experience of Screenhero is undisturbed as we go through this transition. Once we’re done, your experience is going to be far better than it’s ever been. We’re excited to make that happen for you, and we hope you’re excited to be a part of this new incredible journey :)
