Hatching images

With a laser and Voxelizer you can hatch images on your materials.

In the laser workflow go to File → Import → Image. After choosing the image that you want to hatch a new window will appear.

First of all, scale and position the image on your material.

Now it is time to choose how you want the laser to render your image. Choose the generate type between:

• Intensity: will divide the image in pixels big as much as specified in the pixel size parameter and will fill it with straight lines. A black pixel will be filled with the number of lines specified in the lines per pixel parameter, a white pixel will have no lines. Beware of the risk of overburning the material if the lines are too dense.  

• Edges: the algorithm will try to detect the edges of the image and create a path on top of them. Play with the parameters to improve the edge detection (here a detailed explanation of them).

• Hatching: will look for areas with uniform colors and apply and hatching effect to them. The levels count parameter determines the number of areas it should look for.

• Hatching + edges: puts together the hatching and edges types.

Remember that you can influence the results of the algorithms also by changing the saturation values in the sliders at the top of the window.

Once you have decided the desired type of render, you can confirm it and click Next. Once you are in the Laser settings tab you can choose the material that you will work with and then apply an Engrave operation to the generated path. Hatching inside and Hatching outside will not work in this case.

Finally, click Next and generate the g-code to send to your machine.
