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.
