Bore Editor
Users can use arrows to adjust the position, aize and aspect ratio. Keep in mind that position, size and aspect ratio of the bore are independently set up. The change on these attributes does not alter the knob’s attributes.
The bore serves as the background for the progress bar and the liquid column is the foreground. The liquid colume moves according to the value of the binding register but the bore remains staionary.
If the scales are stencils, users can use the bore to show the color through the scales. For example, the bore is darker grey and this color is shown on the scales.
