Re: 2D graphics options with Clojure?
I have been using a longstanding, well-supported Java 2D drawing toolkit called Piccolo2D (http://www.piccolo2d.org/index.html). Here is some text from its home page: - Piccolo2D is a toolkit that supports the development of 2D structured graphics programs, in general, and Zoomable User Interfaces (ZUIs), in particular. A ZUI is a new kind of interface that presents a huge canvas of information on a traditional computer display by letting the user smoothly zoom in, to get more detailed information, and zoom out for an overview. We use a scene graph model that is common to 3D environments. Basically, this means that Piccolo2D maintains a hierarchal structure of objects and cameras, allowing the application developer to orient, group and manipulate objects in meaningful ways. Why use Piccolo2D? It will allow you to build structured graphical applications without worrying so much about the low level details. The infrastructure provides efficient repainting of the screen, bounds management, event handling and dispatch, picking (determining which visual object the mouse is over), animation, layout, and more. Normally, you would have to write all of this code from scratch. Additionally, if you want to build an application with zooming, that's built right into the framework too. What exactly is it? Piccolo2D is a layer built on top of a lower level graphics API. There are currently three versions of the toolkit: Piccolo2D.Java, Piccolo2D.NET and PocketPiccolo2D.NET (for the .NET Compact Framework). The java version is built on Java 2 and relies on the Java2D API to do its graphics rendering. The .NET version is built on the .NET Framework and relies on the GDI+ API to do its graphics rendering. This makes it easy for Java and C# programmers, even those targeting PDAs, to build their own animated graphical applications. And best of all, Piccolo2D is free and open source! - I've been using it with good results; you will need to evaluate it for your purposes. Good luck, and have fun! --Gregg On Apr 29, 9:26 pm, stu stuart.hungerf...@gmail.com wrote: Hi, I'm developing a Clojure project that loads and creates a bunch of simple 2D geometry (lines, polygons, beziers, text etc).

I believe I can use Incanter's wrapping of the Processing libraries for the PNG and again I'm not sure about the PDF option. The Cairo toolkit is also an option via the Gnome Java bindings and Java interop? Are there other options that I'm missing that anyone would like to report on?

Re: 2D graphics options with Clojure?
Processing has PDF exporting capabilities via one of the standard libraries that ship with it: http://processing.org/reference/libraries/pdf/index.html I haven't used it myself, but I remember seeing nice stuff rendered with it. -Roland -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: 2D graphics options with Clojure?
I've also had success with Batik for server-side image generation. As long as you don't mind SVG.

Re: 2D graphics options with Clojure?
Stu, Just a quick thought, you can use Java2D for the images and then iText to create the PDFs.
