Pixelate filters and effectsThe commands in the Pixelate submenu in the Filter and Effect menus sharply define a selection by clumping pixels of similar color values. Note: The Pixelate effects are raster-based and use the document's raster effects settings whenever you apply the effect to a vector object. (See Specifying raster effects settings.)
Color Halftone Simulates the effect of using an enlarged halftone screen on each channel of the image. For each channel, the filter divides the image into rectangles and replaces each rectangle with a circle. The circle size is proportional to the brightness of the rectangle. To use the Color Halftone filter:
Crystallize Clumps colors into polygon shapes. Mezzotint Converts an image to a random pattern of black-and-white areas, or of fully saturated colors in a color image. To use the filter, choose a dot pattern from the Type pop-up menu in the Mezzotint dialog box. Pointillize Breaks up the color in an image into randomly placed dots, as in a pointillist painting, and uses the background color as a canvas area between the dots. |
