The Quartz Composer development team is proud to announce a new
version of both the Quartz Composer Engine and the Quartz Composer
Editor for the release of Mac OS X Leopard. This release was largely
driven by a combination of user feedback (via bug reports and
enhancement requests :) and our own desire to build something we love.
Here's a few highlights of what you'll find:
* A new QCPlugIn API for creating your own patches.
* A redesigned high performance image pipeline.
* A new editor designed to greatly improve workflow including an
infinite workspace, compatibility testing, composition comparison and
even undo!
* Many new patches including patches such as Smooth, Sample & Hold,
Mathematical Expression, OSC, Composition Loader, a new Timelines
patch, a generic XML Downloader patch and many more.
* Updates to many existing patches including the JavaScript patch
which can now store images and structures and a new Core Image Filter
patch.
* iTunes support for Music Visualizers including Jelly, Stix and Lathe.
* A system wide Composition Repository for sharing compositions
throughout the operating system (e.g. Photobooth and iTunes).
* The QCVisualizer: a new application used to render compositions on
networked computers across multiple screens (including source code).
* Automator actions to batch apply effects to images and movies.
* Many new and updated developer examples including compositions,
custom patches, Dashboard widgets and applications. If that's not
enough, the full list of changes are attached.

\f0\b\fs72 \cf0 Release Notes\
For Quartz Composer Leopard
\fs48 \
\b0\fs24 \
\i\fs28 This document lists all the major changes to Quartz Composer in Leopard versus the previous version released in Mac OS X Tiger.
\i0\fs24 \
\
\
\b\fs48 1) Quartz Composer Engine:

\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural

\b0 \cf0 The Quartz Composer image pipeline has been completely redesigned and provides the following major enhancements over its former Tiger implementation:\
\pard\tx220\tx720\pardeftab720\li720\fi-720\sl380\sa20\ql\qnatural
\ls1\ilvl0\cf0 {\listtext \'95 }Accurate color management\
\pard\tx220\tx720\pardeftab720\li720\fi-720\sl380\sa20\ql\qnatural
\ls2\ilvl0\cf0 {\listtext \'95 }Support for arbitrary sized images\

\pard\tx220\tx720\pardeftab720\li720\fi-720\sl380\sa20\ql\qnatural
\ls4\ilvl0\cf0 {\listtext \'95 }Improved sharing of resources between all QCViews, QCRenderers and QCCompositionLayers in the same process\
{\listtext \'95 }Simplified texture properties (texture target, texturing matrix..)\
\pard\tx220\tx720\pardeftab720\li720\fi-720\sl380\sa20\ql\qnatural
\ls5\ilvl0\cf0 {\listtext \'95 }Optimized Image Crop and Image Transform patches\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural

\b\fs36 \cf0 \ul 1.1 Composition Repository:
\fs24 \ulnone \
\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural
\b0 \cf0 To encourage sharing of compositions through the system and applications, there is a new system-wide repository of compositions (which have to comply to standardized sets of inputs / outputs a.k.a. "protocols") located in /System/Library/Compositions, /Library/Compositions and ~/Library/Compositions. Users and installers can add new compositions to those places, while the repository can be easily be queried by application clients using new APIs.\
\

\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural
\b\fs36 \cf0 \ul 1.2 Support For Virtual Patches:
\fs24 \ulnone \
\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural
\b0 \cf0 It's now possible to use composition files as virtual patches if placed into "/Library/Graphics/Quartz Composer Patches" or "~/Library/Graphics/Quartz Composer Patches". Any composition file in these directories will appear like a native patch to Quartz Composer. You can instantiate them in your compositions like any regular built-in patches, but contrary to editor clips, each instantiation results in a non-editable virtual copy, instead of a real autonomous copy. Furthermore, when saving a composition file that uses virtual patches, only weak references are stored: if the composition file corresponding to a given virtual patch has been modified, or is simply missing, its dependend composition files will be affected.\
\
If you want remove all dependencies to virtual patches from a composition, select "Save a Copy As..." while pressing the Option key, and this will save a flattened copy of the composition that embeds real copies of the virtual patches.\

\ls8\ilvl0\cf0 {\listtext \'95 }Affine Transform is now Image Transform - No longer has Texture Format and Parameters.\
{\listtext \'95 }Audio Input - Added fall speed inputs for peak and spectrum and an option to turn on specific source listening. When this is off all sources are listened to. \
{\listtext \'95 }Billboard - A new setting for determining image dimensions has been added. Force pixel alignment is good for ensuring images do not get blurred by straddling pixel boundaries but is not suited for billboards which are animated because the movement will appear choppy as the image jumps from pixel to pixel.\
{\listtext \'95 }Core Image Accumulator - Image dimensions are now an input, Texture format and Parameters have been removed.\
{\listtext \'95 }Core Image Filter - Domain of Defintion is a union of input samplers. New advanced input sampler options are available. It is now possible to edit the filter function and call multipass core image routines.\
{\listtext \'95 }Folder Images became Directory Scanner, with an option to scan for images, movies or compositions.\
{\listtext \'95 }Gradient - Variable number of gradient points, at user defined positions. More direction modes were also added.\
{\listtext \'95 }Host Info - CPU load is now a structure instead of separate output ports.\
{\listtext \'95 }Image Crop - The crop patch is no longer a Core Image filter and is instead handled directly in QC for better performance and less image transformations.\
{\listtext \'95 }Image Downloader - Update Signal to tell the image downloader to reload the image. Removed Texture Format and Parameters. Synchronous Download option to ensure the composition does not continue until the image has loaded. Disable Color Correction setting added. Also outputs the progress of the download.\
{\listtext \'95 }Image Importer - Texture Format and Parameters removed. Disable Color Correction setting added.\
{\listtext \'95 }Image Texturing Matrix is now Image Texturing Properties, has added Target and Mipmapping options.\
{\listtext \'95 }Image With Movie is now Movie Loader - Movie playhead position output, Asynchronous mode setting added (for audio syncing). To decompress a video directly at a specific size, Frame dimensions setting has been added. Deinterlace hint, Clean aperature, Disable color correction settings have also been added.\
{\listtext \'95 }Image With String - Texture Format and Texture Parameters are no longer available on this patch. Quartz Composer has improved support for images that are larger than can fit on the video card.\
{\listtext \'95 }Javascript - Typed return values, function declarations, improved image and structure support.\
{\listtext \'95 }Lighting - Added a setting to control when the specular color is computed. This is necessary for the antialiasing feature added to the Sprite.\
{\listtext \'95 }Math - UI change to make number of operations visible.\
{\listtext \'95 }Midi Clock - Option to listen to all midi sources.\
{\listtext \'95 }Midi Controllers - Option to listen to all midi sources, Listen button to add the next modified controller to the observed controllers list.\
{\listtext \'95 }Midi Notes - An option to listen to all midi sources has been added. There is also a setting to translate the labels on the midi notes to match other applications.\
{\listtext \'95 }Mouse - Scroll wheel support added.\
{\listtext \'95 }Multiplexer - UI changed so that Number of Inputs is visible\
{\listtext \'95 }Particle System - Particle Count is now an input. Interpolate Size and Color adds inputs for a target size and an interpolation mode to arrive there over the lifetime.\
{\listtext \'95 }Psychedelic - Clear Depth Buffer setting\
{\listtext \'95 }RSS Feed is now RSS Downloader - Update signal input for reloading article, a setting to preserve HTML in contents, Preserve Extensions option for non-RSS xml elements, and an Synchronous dowload option to ensure the RSS is loaded before the composition continues. Also outputs the progress of the download.\
{\listtext \'95 }Random - Now works in an iterator when "Use Perlin Noise" is selected. New instances of this patch do this automatically, but old compositions retain their previous random behavior.\
{\listtext \'95 }Render in image - Inputs for Texture Target and Mip Mapping, dimensions. Settings for Depth Buffer Rendering, Feedback rendering and color matching.\
{\listtext \'95 }Sphere - Scale input is now Diameter\
{\listtext \'95 }Splitter - When the splitter has type "Index" and the range is bounded, index elements can be named. These show up as labels on the splitter and parameter views in Quartz Composer and client applications.\
{\listtext \'95 }Sprite - Resolution setting to add fragments and verticies for GLSL to act upon. Added an Antialiased Edges setting, allowing sprite edges which are not pixel aligned to be smooth. This setting requires that the sprite's blend mode be "Over" or "Add".\
{\listtext \'95 }Stop Watch - Refactored start modes to be more intuitive.\
{\listtext \'95 }TrackBall - Track Mouse allows you to disable mouse tracking as needed.\
{\listtext \'95 }Video Input - Added a Capture input to enable camera, video device selector, Clean aperature and color correction settings, removed Image Dimensions, Texture Format and Texture Parameters\

\cf0 \'95 For optimal image passing between multiple QC renderers, a new opaque image type is supported: QCImage.\
\'95 The methods [QCRenderer attributes] and -[QCView attributes] now returns all metadata stored in the composition.\
\'95 When looking at port attributes for index ports, QCPortAttributeMenuItemsKey may be present and contain an NSArray of NSStrings representing the menu item titles.\
