![]() ![]() ![]() Beside circles, squares and stars, you can also include your own shapes from separate image files. The dot patterns can be adjusted by increasing or decreasing the dot size as well as their shape. The application enables you to add a variety of pattern types, such as dots, waves or jitter. Using the included slider, the amount of lines per inch can be increased or decreased as well and you can choose between the square, triangle or hexagon layouts. In addition, you can also change the resolution by increasing or decreasing the DPI level, which also deeply affects the overall quality of the photo. Before applying any pattern, you can prepare the image by adjusting its main characteristics, such as brightness, contrast and general smoothness level. Halftone is a plugin utility that enables you to easily manipulate your pictures in a variety of ways, but also create a wide variety of patterns using dots, shapes and various other tools. Adjust the brightness, resolution and layout type There are no exact rules that apply in the case of pattern creation, since the result differ greatly depending on the image in question. Although this drilling function is incorporated into other commercial software, this program, which is free to download and use (under the GNU Public License) has many advanced features and the inbuilt post-processor produces fully Mach compatible GCode.Image manipulation is a precise field when it comes to various quality adjustments, such as sharpness, brightness and contrast, but it can also require a bit of an artistic eye. The first one I found (DotG) uses a ‘dot-dithering’ technique (similar to half tone) with the GCode that is produced being eminently suited to dot impact or laser use and I posted details in this thread Īnother software (DXF Halftone 2.1) is more true to the half tone technique and is best suited to varying depth V bit drilling. Over the last week or so I have been looking at ‘free of charge’ options for CNC production of half tone images. ![]()
