Quartz Composer Application

MiniBooth                   A very simplified Photo Booth that shows how to combine 

                        the Composition Repository with the Composition Loader 

                        patch to apply image filtering on video output, and how 

                        to save the QCView contents as a PNG image file.

Sample Requirements             The project was created using the Xcode running under 

                        Mac OS X 10.6.x or later. The supplied Quartz Composer 

                        compositions were created using the Quartz Composer editor 

                        running under Mac OS X 10.6.x or later.

About the sample                In the sample, the user can select an image filter in the 

                        composition picker to generate videos with special effects. 

                        The supplied composition grabs the input video and output 

                        a sequence of images. The images are then processed with an 

                        image filter selected by the user to produce video with 

                        special effects. A QCCompositionPickerPanel is used to 

                        provide the image filters for the user to select. When a filter 

                        is selected, the application will receive a notification and 

                        it will pass the selected filter identifier as the new input 

                        parameter for the composition in the QCView. This filter is 

                        then applied to process the images.

Using the Sample                Open the project using the Xcode editor which can be found in 

                        /Developer/Applications. Build the project and run. Select the 

                        image filter from the composition picker to see the new results.
