Generators, Gradients, & Halftone Effect
Many of the filter definitions below come directly from Apple’s core image filter reference.
Generators
Checkerboard: Generates a checkerboard pattern. You can specify the checkerboard size and colors, and the sharpness of the pattern.
|
|
|
Circles: Adds concentric circles to your image. |
|
|
|
|
|
Grid: Generates a grid with modifiable positioning, color, distance, and width. |
|
|
Lenticular Halo: Simulates a lens flare. |
|
|
Random Generator: Generates an image of infinite extent whose pixel values are made up of four independent, uniformly-distributed random numbers in the 0 to 1 range. |
|
|
Random Noise: Creates random noise with option for grayscale. |
|
|
Render Clouds: Generates cloud-like noise, also known as Perlin-noise. |
|
|
Star Shine: Generates a starburst pattern that is similar to a supernova; can be used to simulate a lens flare. |
|
|
Stripes: Generates a stripe pattern. You can control the color of the stripes, the spacing, and the contrast. |
|
|
Sunbeams: Generates a sun effect. |
|
|
Sunburst: Generates a two color sunburst. |
|
|
Gradients
Linear Gradient: Generates a gradient that varies along a linear axis between two defined endpoints. |
|
|
Radial Gradient: Generates a gradient that varies radially between two circles having the same center. |
|
|
|
|
|
Smooth Linear Gradient: Generates a gradient that uses an S-curve function to blend colors along a linear axis between two defined endpoints.
Halftone Effect
Circular Screen: Simulates a circular-shaped halftone screen. |
|
|
CMYK Halftone: Creates a color, halftoned rendition of the source image, using cyan, magenta, yellow, and black inks over a white page. |
|
|
Dot Screen: Simulates the dot patterns of a halftone screen. |
|
|
Hatched Screen: Simulates the hatched pattern of a halftone screen. |
|
|
Line Screen: Simulates the line pattern of a halftone screen. |
