Rasterize Objects (Convert Vector Design to Bitmap)


In this article, you'll learn how to convert vector objects to images inside an SVG file using Inkscape and Adobe Illustrator

What is rasterizing?

Rasterizing is the process of taking an object which is stored as series of strokes and fills in an SVG or other vector file and converting the object into an image made up of individual dots (or pixels). Rasterized images, also called “Bitmaps,” can only be engraved, not cut or scored. PDF and SVG files can contain both vectors and raster images. 

There are some scenarios, however, where you might want to rasterize all or part of your design instead. Here are two examples of when rasterizing can be useful:

  • Very complex engraves can upload and process more quickly as bitmaps, so your amazing print will be ready sooner. 
  • When you upload a file to the Glowforge app, stroke weight (thickness) or any stroke styles such as dotted or dashed lines are preserved if your design is a bitmap, and that means your vision will be realized. 
  • Some vector features like gradients and live shapes work best when rasterized.

 

How to rasterize objects in Inkscape

  1. Open your design in Inkscape.

  2. Open the preferences menu by clicking Edit > Preferences

  3. In the window that opens, navigate to the Bitmap settings. Enter a dpi value in the "Default export resolution" and "Resolution for Create Bitmap Copy" fields following the example below.

    Files with a large number of high-resolution images will take longer to upload and to be prepared for printing in the app. Most customers find that their prints turn out beautifully with a dpi of 300.

  4. Close the Preferences window.
  5. Click on the selection tool Screenshot of the Inkscape selection tool, and then choose the object or objects you want to rasterize.

  6. With the object(s) selected, click Edit > Make a Bitmap Copy.

  7. A copy of the object will appear as a new raster layer. 

  8. To delete the vector layer, click Object > Lower to Bottom, then click on your shape again and press the delete key.
