Add CIFilter Noise

Question

Are there any CIFilters that have a similar effect on the Photoshop filter "add noise"?

Answer 1

You can use CIRandomGenerator in combination with some blending filter (add, screen, or something else). A whole chain of effects should be:

• Create a noise map
• Blend it with the source text.
• Cropping at original size

In addition, it would be useful to prepare your own noise texture and write something like a random generator using a CIAffineTile filter with a transform that transforms the image randomly.
