With the introduction of Quartz Composer in Mac OS X Tiger, Apple. Quartz composer MTC trigger patch for mediaserver Video CLIPGO! Is a Quartz Composer PATCH for taking Midi TimeCode/LinearTimeCode source (ltc could be but only via lockstep for translate LTC in MTC and sending it to QC). You can declare specific timing for any midi trigg via Midi output to Resolume Arena. It could be useful to launch more.
Also new in Version 3.0 was the possibility to write custom patch plugins, using an Xcode template, and the notion of a 'safe mode', where plugins and other unsafe patches fail to load. This prevents malicious compositions from performing dangerous or insecure operations. Custom patches using Apple's Xcode template are always considered unsafe. It was possible to develop custom patch plugins for Version 2.0, but the API was undocumented and private, and was never supported by Apple. Eventually, templates were released to simplify this procedure.[5] Hidden optionsIn the Quartz Composer editor, holding the option key while selecting 'Preferences...' from the menu adds 3 additional tabs of options for the user to configure. These options include System settings, Editor settings, and QuickTime integration settings. Notable options include expanded tooltips, software rendering, and uncapped framerate rendering. Multisample antialiasing (MSAA) was added as a hidden option in version 4.0, allowing for antialiasing inside the QC Editor, though it only works on GPU's that support MSAA. Native datatypesData inside QC can be one of the following types:
Two additional types were introduced in version 4.0:
Type conversionData can usually be converted to other types transparently. In Quartz Composer 3.0, the connections between patches change color to indicate conversions that are taking place. Yellow connections mean no conversion is taking place, Orange indicates a possible loss of data from conversion (Number to Index), and Red indicates a severe conversion; Image to Boolean, for example. CompositionsQuartz Composer documents are called Compositions. Compositions are Binary Property Lists (though XML versions are also supported) with a filename extension.qtz, and a com.apple.quartz-composer-compositionUTI.[6] Patches, their connections, and their input port states are saved in the composition file. Images can be stored inside a composition as well, making for self-contained compositions with embedded graphics. By dragging a movie file into the Quartz Composer editor, a reference to the movie file is created, providing a changing image that can be connected to a renderer. Compositions also store metadata such as composition author, copyright, and description. The user can also add arbitrary metadata items, if desired. Many image formats are supported, including JPEG, JPEG2000, GIF, PNG, TIFF, TGA, OpenEXR, BMP, ICO, PDF, PICT, ICNS, and some raw digital camera types.[7] Images are maintained in their native form for as long as possible before rasterizing for display. This means that Quartz Composer will keep vector images as vectors when cropping, scaling, rotating, or translating which allows it to work with very large logical image dimensions without consuming large amounts of memory or processing time. Such functionality is most apparent when working with text-based images, or PDFs. Version 3.0 added the ability to add annotations to areas of the composition, called notes. These notes parallel comments in other programming languages. Notes can be yellow, red, green, blue, or gray, and can overlap other notes. Composition protocolsIn Version 3.0, the concept of Composition Protocols was introduced. Protocols provide a template of required and optional inputs and outputs to qualify conforming compositions for various purposes. The following protocols are available by default:
There is an additional protocol that Apple uses in their private API:
One new protocol was added in version 4.0:
There is no officially supported way to add additional protocols to Quartz Composer. However, there are some undocumented methods that may make this possible in the future.[8] Composition runtimesIn addition to protocols, compositions can also conform to different runtimes where Quartz Composer is available. In Leopard, there are runtimes for Tiger (32-bit), as well as 32-bit and 64-bit versions of the Leopard Quartz Composer runtime. The editor can also indicate used patches that are unsafe, or unavailable in Tiger to aid in making compatible compositions. Composition repositoryA System-wide Composition Repository is available as of Version 3.0.[9] This allows applications to share and make use of common compositions for effects and processing. It is also possible for applications to query the repository for compositions that match certain criteria, such as protocol conformance. The Repository is spread across 3 file system locations:
Adding compositions to the repository is as simple as adding the composition file to one of these locations. Comparing compositionsIt became possible to compare compositions in Quartz Composer 3.0. This feature allows the user to compare inputs, rendered output, and graph appearance of any two compositions. Related softwareQuartz Composer VisualizerA developer tool called Quartz Composer Visualizer was released with Quartz Composer 3.0 that allows compositions to be rendered across multiple screens on a single machine, or even spanned across several machines and displays. Automator supportSupport for some Automator actions was added with the release of Leopard.
HistoryPierre-Olivier Latour originally developed the predecessor to Quartz Composer under the name PixelShox Studio.[10] Related Research ArticlesGIMP is a free and open-source raster graphics editor used for image retouching and editing, free-form drawing, converting between different image formats, and more specialized tasks. Adobe Photoshop is a raster graphics editor developed and published by Adobe Inc. for Windows and macOS. It was originally created in 1988 by Thomas and John Knoll. Since then, this software has become the industry standard not only in raster graphics editing, but in digital art as a whole. The software's name has thus become a generic trademark, leading to its usage as a verb although Adobe discourages such use. Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing, and several color models including RGB, CMYK, CIELAB, spot color, and duotone. Photoshop uses its own PSD and PSB file formats to support these features. In addition to raster graphics, this software has limited abilities to edit or render text and vector graphics, as well as 3D graphics and video. Its feature set can be expanded by plug-ins; programs developed and distributed independently of Photoshop that run inside it and offer new or enhanced features.A software synthesizer, also known as a softsynth or software instrument, is a computer program or plug-in that generates digital audio, usually for music. Computer software that can create sounds or music is not new, but advances in processing speed now allow softsynths to accomplish the same tasks that previously required the dedicated hardware of a conventional synthesizer. Softsynths are usually cheaper and more portable than dedicated hardware, and easier to interface with other music software such as music sequencers. Pidgin is a free and open-source multi-platform instant messaging client, based on a library named libpurple that has support for many instant messaging protocols, allowing the user to simultaneously log into various services from one application. Adium is a free and open source instant messaging client for macOS that supports multiple IM networks, including Windows Live Messenger, Yahoo! Messenger, Google Talk, AIM, ICQ and XMPP. It is written using macOS's Cocoa API, and it is released under the GNU General Public License and many other licenses for components that are distributed with Adium. CUPS is a modular printing system for Unix-like computer operating systems which allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer. Graphviz is a package of open-source tools initiated by AT&T Labs Research for drawing graphs specified in DOT language scripts. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License. The following comparison of video players compares general and technical information for notable software media player programs.

ITK is a cross-platform, open-source application development framework widely used for the development of image segmentation and image registration programs. Segmentation is the process of identifying and classifying data found in a digitally sampled representation. Typically the sampled representation is an image acquired from such medical instrumentation as CT or MRI scanners. Registration is the task of aligning or developing correspondences between data. For example, in the medical environment, a CT scan may be aligned with an MRI scan in order to combine the information contained in both. The Apple Developer Tools are a suite of software tools from Apple to aid in making software dynamic titles for the macOS and iOS platforms. The developer tools were formerly included on macOS install media, but are now exclusively distributed over the Internet. As of macOS 10.12, Xcode is available as a free download from the Mac App Store. ParaView is an open-source multiple-platform application for interactive, scientific visualization. It has a client–server architecture to facilitate remote visualization of datasets, and generates level of detail (LOD) models to maintain interactive frame rates for large datasets. It is an application built on top of the Visualization Toolkit (VTK) libraries. ParaView is an application designed for data parallelism on shared-memory or distributed-memory multicomputers and clusters. It can also be run as a single-computer application. A display server or window server is a program whose primary task is to coordinate the input and output of its clients to and from the rest of the operating system, the hardware, and each other. The display server communicates with its clients over the display server protocol, a communications protocol, which can be network-transparent or simply network-capable. DIPS is a set of plug-in objects that handle real-time digital image processing in Max/MSP programming environment. Combining with the built-in objects of the environment, DIPS enables to program the interaction between audio and visual events with ease, and supports the realization of interactive multimedia art as well as interactive computer music. Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, iPadOS, macOS, watchOS, tvOS, Linux, and z/OS. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products. It is built with the open source LLVM compiler framework and has been included in Xcode since version 6, released in 2014. On Apple platforms, it uses the Objective-C runtime library which allows C, Objective-C, C++ and Swift code to run within one program.
