Furthermore, if the job is very small, the quality may not be sufficient, because the fixed quality value is a compromise chosen for larger jobs. This means that large jobs require large calculation times because all the details are sought, even the most insignificant ones. Sometimes an image with a too high resolution produces details that we would like to avoid, for example: jagged edges, stains, strokes erased with the eraser… Downsampling allows to lose all these details and keep only the main theme of the image.īy default Vectorization tool use a fixed quality regardless of the size of the work to be done. This is only an optimization in G-Code line count that has a minimal effect on the image. Simplify and optimize detected paths to minimize final segments count. Smoothes the sharp edges, producing a softer image Do not use if you if you want to preserve small details of the image.
With spot removal paths with smallest area of the threshold will be removed from the final output. Usage Vectorization tool options Spot removal Play with brightness and contrast controls to include or cut-out the lighter areas of the image. To do that it first decide what is black and what is white, using a threshold. Vectorization follows black borders inside image and create vector paths. There are no limits in the power of this tool, which together with the brightness and contrast controls allow optimum results with any type of image. Vectorization is provided by Potrace alghoritm, by Peter Selinger. This tool allows you to open any logo downloaded from the Internet (or drawn freehand) clean graphical elements of disturbance like whiskers, spots or watermarks, and engrave it with the best vector quality. The vectorization tool is the most powerful instrument of LaserGRBL.
