This shows how Knotter can be used to trace a knot from a picture of the knot.

Loading the image

The first step is to load the image as a background in a new knot.

In the default settings the background dialog is not shown, this can be changed with View → Dialogs → Background Tutorial picture1.png

As with most dialogs, it can be docked to the side of the window. Tutorial picture2.png

Now we have to enable a background image. Tutorial picture3.png

And load it, using the Browse... button. Tutorial picture4.png

The image is now loaded, we can pan to the desired location or move the image from the dialog. Tutorial picture5.png

For the first part the grid can be disabled. Tutorial picture6.png

Sketching the knot

We can now zoom in and use the Edge loop tool. Tutorial picture7.png

We can now start placing the nodes in the canvas with the left mouse button.

It may take some experience to understand where to place them. This process, called "extraction" is described in Celtic Knotwork: the ultimate tutorial - Extraction
