Workflow: Existing Bitmap Image

Peter van der Walt edited this page Jul 20, 2016 · 7 revisions
  1. Find an existing image / draw an image in the application of your choosing

Here I'm just grabbing a random image of Google Images (no copyright infringement meant)

  1. JPEG, GIF, BMP and PNG are all supported

  2. Open the file in LaserWeb

Now, you have two option: Raster it as is, or Trace (convert) it to a Vector paths:

Raster Engraving

  1. Adjust the "bitmap resolution" to the correct DPI for the image (understanding DPI falls beyond the scope of this guide. But lets say you draw a picture for 100x100mm at 150DPI, the resulting PNG will be (100mm / 25.4mm * 150 = 886x886 pixels big. To get the pixels back to MM we scale it by the appropriate DPI. You can also cheat a little and play with the DPI till the size is achieved that you want the picture to be.

  1. Ajust speed and power setting appropriate to your machine

  2. Click Generate GCode: It will take a few seconds to convert the bitmap into a RASTER

  1. Run the job: The result of a Raster job, is a finely grayscaled image. Usually better suited to photographs and gradients. Unfortunately, lasering a raster is a time consuming job, since it scans over the image creating it line by line
