SyphonServer is used to make frames available to other applications. SyphonServerDirectory is used to discover available servers. SyphonClient is used to connect to and receive frames from a SyphonServer. + + The framework <em>requires</em> MacOS X 10.6 or later. Syphon makes use of IOSurface, which is a 10.6-only technology. Syphon takes advantage of other 10.6 features such as blocks, and is compatible with garbage-collection. + + To include Syphon in your application, follow these steps: + + <ol> + <li><h4>Add the framework to your Xcode project.</h4> + <p>The simplest way is to drag it to the Linked Frameworks group in the project window.</p></li> + <li><h4>Link your application with Syphon at build time.</h4> + <p>Add the framework to the Link Binary With Libraries build stage of your application's target.</p></li> + <li><h4>Copy the framework into your application's bundle.</h4> + <p>Add a new Copy Files build phase to your application's target.<br/> + Get Info on the build phase and select Frameworks as the destination.<br/> + Drag the Syphon framework into the build phase.</p></li> + <li><h4>Import the headers.</h4> + <p>#import <Syphon/Syphon.h> in any file where you want to use Syphon classes.</p></li> + </ol> + + @section servers Servers + + Class documentation: SyphonServer + + Create a server: + + @code + SyphonServer *myServer = [[SyphonServer alloc] initWithName:@"My Output" context:myContext options:nil]; + @endcode + + and then publish new frames (you can also use GL_TEXTURE_2D textures): + + @code + [myServer publishFrameTexture:myTex textureTarget:GL_TEXTURE_RECTANGLE_EXT imageRegion:NSMakeRect(0, 0, width, height) textureDimensions:NSMakeSize(width, height) flipped:NO]; + @endcode + + Alternatively there are methods to bind and unbind the server to the OpenGL context, so you can draw into it directly. + You can publish new frames as often as you like, but if you only publish when you have a frame different from the previous one, then clients can do less work. + You must stop the server when you are finished with it: + + @code + [myServer stop]; + @endcode + + @section finding-servers Finding Servers + + Class documentation: SyphonServerDirectory + + SyphonServerDirectory handles server discovery for you. You can get an array of dictionaries describing available servers: + + @code + NSArray *available = [[SyphonServerDirectory sharedDirectory] servers]; + @endcode + + The servers property can be observed for changes, or you can register to receive the notifications posted by SyphonServerDirectory. + + Server description dictionaries are used by Syphon when you create a client, and also contain information you can use to describe available servers in your UI: + + @code + [myMenuItem setTitle:[description objectForKey:SyphonServerDescriptionNameKey]]; + @endcode + + @section clients Clients + + Class documentation: SyphonClient, SyphonImage + + Usually you create a client with a server description dictionary you obtained from SyphonServerDirectory: + + @code + SyphonClient *myClient = [[SyphonClient alloc] initWithServerDescription:description options:nil newFrameHandler:^(SyphonClient *client) { + [myView setNeedsDisplay:YES]; + }]; + @endcode + + The new-frame handler is optional: you can pass in nil. Here we use it to tell a view it needs to draw whenever the client receives a frame. + + When you are ready to draw: + + @code + SyphonImage *myFrame = [myClient newFrameImageForContext:cgl_ctx]; + if (myFrame) + { + GLuint tex = myFrame.textureName; + NSSize dimensions = myFrame.textureSize; + + // YOUR OPENGL DRAWING CODE HERE + + [myFrame release]; + } + @endcode + + As with servers, you must stop the client when you are finished with it: + + @code + [myClient stop]; + @endcode + + @section plugins Syphon.framework in a Plugin + + If you are using Syphon in any sort of plugin, please download the framework source and compile a version of the framework with unique class names. This avoids class-name conflicts if another plugin or the host application also embeds the Syphon framework. The framework source is set up to make this easy for you: you just need to change one build setting. + + <ol> + <li><h4>Open the framework's Xcode project.</h4> + <p></p> + </li> + <li><h4>Define SYPHON_UNIQUE_CLASS_NAME_PREFIX using the Preprocessor Macros build setting.</h4> + <p>Select the Syphon target in the project window.<br/> + Get Info on the target, and click the Build tab to display the build settings.<br/> + Scroll down (or use the search field) to find the Preprocessor Macros (GCC_PREPROCESSOR_DEFINITIONS) setting.<br/> + Double click the setting to add SYPHON_UNIQUE_CLASS_NAME_PREFIX=MyPluginName as a macro. + </p></li> + <li><h4>Build the framework.</h4> + <p>The built framework will have custom class names. The headers alias the custom names, so you can use SyphonServer, SyphonClient, SyphonImage and SyphonServerDirectory as normal in your code.<br/> + </p></li> + </ol> + + @section help More examples and help + + Example projects implementing a server and client are included with the Syphon SDK. You can also examine the source to the provided Syphon implementations at their <a href="http://code.google.com/p/syphon-implementations/" target="_blank">Google Code project</a>. + + Use the <a href="http://forums.v002.info/forum.php?id=7" target="_blank">Syphon developer forum</a> to ask questions, and for any development related discussion. + + Good luck! + + @section framework_dev Framework development + + If you'd like to examine the framework's source code, report a bug, or get involved in development, head on over to the <a href="http://code.google.com/p/syphon-framework/" target="_blank">Syphon framework Google Code project.</a> + + */
