Name

dotgen - make an image of two crossed sinusoidal wave patterns

Synopsis

dotgen outimage size scalex scaley [-a]

Description

dotgen generates an image of two crossed sinusoidal wave patterns. The output image can be used as input to thresh to create halftoned images. The output of dotgen is a square image size pixels on a side. scalex and scaley are floating point values that can be used to change the density and rotation of the dot pattern. If they are both integers, the output image will match up with its self when it tiles the plane. The -a option causes dotgen to take the absolute value of the sum of the two sinusoids.
