Previewing a composition in Vuo and understanding how it will run in other contexts
When you run an Image Generator, Image Filter, or Image Transition composition with the Run button, Vuo feeds data and events into the published input ports and displays the published output image in a window. This makes it easy to preview how the composition will look when run inside of an exported product or another application.
You can change the images the Vuo feeds into protocol published input ports. For an Image Filter composition, drop an image file onto the running composition’s window to change the image being filtered. For an Image Transition composition, drop an image file onto the left or right half of the window to change the start or end image, respectively.
