Pixelate filters

Color Halftone

The Color Halftone filter simulates the result of using an enlarged halftone screen on the layer. 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.

Apply the Color Halftone filter

  1. In the Edit workspace, select an image, layer, or area.
  2. Choose Pixelate > Color Halftone from the Filter menu.
  3. Enter a value for the maximum radius of a halftone dot, from 4 to 127 pixels.
  4. Enter a screen-angle value between ‑360 and 360 (the angle of the dot from the true horizontal) for one or more channels:
    • For grayscale images, enter a value in channel 1. Values in the other channel text boxes do not affect the filter.

    • For color images, use channels 1, 2, 3, and 4, which correspond to CMYK channels (cyan, magenta, yellow, and black).

  5. Click Defaults to return all the screen angles to their default values, and then click OK.


The Crystalize filter redraws a layer as polygon-shaped clumps of color. You can set the cell size of the crystals.


The Facet filter redraws a layer as blocks of solid color. You can use this filter to make a scanned image look hand-painted or to make a realistic image resemble an abstract painting.


The Fragment filter redraws a layer so that it appears offset and blurred.


The Mezzotint filter redraws a layer as a random pattern of black-and-white areas in a grayscale image, or fully saturated colors in a color image. You can choose a dot, line, or stroke pattern.


The Mosaic filter redraws a layer as square blocks of color. You can set the mosaic cell size.


The Pointillize filter redraws a layer as randomly placed dots, as in a pointillist painting, and uses the background color in the toolbox as a canvas area between the dots. You can set the cell size.
