Affine Clamp in Filter
Performs an affine transform on a source image and then clamps the pixels at the edge of the transformed image, extending them outwards. This filter performs similarly to the CIAffineTransform filter except that it produces an image with infinite extent. You can use this filter when you need to blur an image but you want to avoid a soft, black fringe along the edges.
Note that the image produced by this filter may have infinite dimensions. If this is the case, since Quartz Composer doesn’t know how to render such images, you will need to convert it to finite dimensions before rendering it – typically using the Image Crop patch.
Core Image filters might not produce any image if any of their image inputs are undefined. Be also aware that they expect coordinates expressed in image pixels and not in Quartz Composer units.
