Remove horizontal or vertical lines

The features described here automatically remove the y- and x-axes, or in general vertical or horizontal lines that span a certain fraction of the diagram part.

The methodology is simple: If a certain pixel column or row in the binary data image is covered, it is considered as a vertical or horizontal line, respectively.

x-axes	y-axes
horizontal lines	vertical lines

You can modify the recognition using three options

Maximum line width:

Lines are only selected up to the given maximum axis width
