Quartz Composer Application

ImageFX                     An application that explains how to use Quartz Composer 

                        QCView and QCCompositionPickerView to render image with 

                        special effects provided by Quartz Composer Image Filters.

Sample Requirements             The project was created using the Xcode running under 

                        Mac OS X 10.6.x or later.

About the sample                In the sample, the user can drag an image into the 

                        rendering window on the right. This rendering window is 

                        an QCView object. It handles the events such as 

                        draggingEntered, DraggingExit, and so on. When an image 

                        is dragged into the QCView, an image filter selected 

                        from the QCCompositionPickerView on the top left is 

                        applied to render the image with special effects. The 

                        QCCompositionPickerView is initialized with image 

                        filters. When the user selects a filter from the picker 

                        view, a large preview image of that effect will be 

                        shown in the QCView window. The user is allowed to 

                        change the input parameters for the selected image 

                        filter. The image in the QCView can also be dragged 

                        outside of the application window to make a copy of the 

                        image.

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

                        found in /Developer/Applications. Build the project and 

                        run. Drag an image to the preview window, select the 

                        image filter from the picker panel and change the 

                        filter parameters.
