Beginners' Questions Using existing PNG image to create a new SVG

    Good morning all.

    I have a PNG image that I want to have it made a SVG to cut in my Cricut. It is a simple image, but I do not know how to proceed with the process. This is the image and the other shows how I need it once complete. Is it possible to use the existing image at all or do I have to create a new one? Thank you.

    I started with your dark egg. Bitmap tracing doesn't work well because there isn't enough contrast between light and dark. Use a filter to resolve this.
      [Filters > Color > Lightness-Contrast]
      [Lightness: 60] [Contrast: 40]
      [Apply]

    Create a bitmap copy of the filtered image.
      [Edit > Make a Bitmap Copy] or [alt+b]

    Now trace the image.
      [Path > Trace Bitmap]
      [Single scan]
      [Detection Mode: Centreline Tracing]
      [Apply]

    This fits a path to the egg outline with a few stray nodes to clean up around the image boundary.

    Paddy - 
    Never thought of using Inkscape's filter capabilites to do that - thanks. I always manipulated hard to vectorize images in an "ancient" photo editor (Yes Picasa 3 From Google - lol).

    Now you got my gears in my head working. Be a nice feature to have some basic filter capabilites in the trace bitmap dialog. Bypassing the need to make a bitmap copy first. To make the tool work even better, instead of having the trace bitmap preview in that tiny dialog, overlay the preview over the original image so you can zoom in and decide if that is what you really want before you apply. 

    Added to my feature wishlist

    Thank you so much. I will give that a try. Once you have all traced up, I can just insert a rectangle and attach both to have it as in the photo?
