Pop Art > Dots
The Dots filter allows you to create colorful dots in the background.
1. Do one of the following:
 Choose Pop Art > Dots
Click the Dots button
2. Use the following options:
Threshold = 64Threshold = 128Threshold = 192
This option allows you to change the threshold value. Pixels whose grayscale value is less than or equal to a certain threshold are set to the foreground color (or primary color). Pixels whose grayscale value is bigger than a certain threshold are set to background color (or secondary color).

Min = 0, Max = 255, Default = 128.
  Size (px)
Length = 8Length = 4
Use this option to change the length of a line segment. The length of a line segment is the distance between two points of a polygon. The larger the distance the lower the complexity of the polygon. If the distance is too large, the image will become disordered.

Min = 1, Max = 50, Default = 5.
  Vectorize Image
Vector imageRaster image
Use this option to vectorize the image. Vectorization is the conversion of raster graphics (pixels) into vector graphics such as points, lines, curves, and polygons. The original raster image is converted into vectorized polygons.
This option allows you to draw a smooth line through the corner points of a polygon. When this option is unselected, the corner points of the polygon are connected by straight lines.
  Foreground Color
This option allows you to change the foreground color.
OK + Export as Layers
This option allows you to apply the effect and create multiple layers, each of which can be manipulated without affecting any other part of the image.
