Plugins: Halftone

Halftone generates a path from an image to reproduce the effect of a technique that simulates continuous tone imagery through the use of dots. Here the dots are drawn as circles to give to user a nice feedback over the result. Circle can be later be processed by pocket function to generate a flat circle out of the material. Halftone can also generate a variable depth drill path to be used with a conical end-mill. Provide correct parameters (type and angle) in the end mill database. The more and bigger the dots, the deeper the drill will be.

Image to process: path to the image file to be processed.
Channel to analyze: can be the luminance (brightness) or red,green,blue channel. Colored channel is value is square rooted to allow a combination of the colored channel keeping overall luminance.
Invert Colors: tick if you are using a black stock with light material under the surface.
Max draw size (Width or Height): the maximum size will be apply to the greater dimension (height or width) while the other dimension will be calculated to keep the aspect ratio.
Cell size: size of the single dot
Max diameter, cap limit: dots over this size will be limited to this value
Min diameter, cut off: dots under this size will be ignored
Image rotation angle: rotate image by this angle. Useful to create an RGB image and avoid Moiré effects (try to use 0,15,30 degrees as example)
Draw border: draw border of the image using working depth
Working Depth: if not using conical option, the depth at which the path will be generated
Generate for conical end mill: tick here if you are using a conical end-mill to generate variable depth drill based on circle diameter.
