idea to just delete half of the points to get a half ellipse. To make a half ellipse it is
better to set the color of one half of the points to black and thus make them invisible.
Furthermore the points of an ellipse should not be moved, as this could lead to very
large drawing distances – which can destroy the scanner system!
In case such adaptions need to be made, it is better to use a polygon with
about 50 points. The optimization method for the dangerous points can also
be changed with a click on the Wrench Tool
change properties of points.
For more information see the description of the wrench tool (see Chapter 56).
6.2.11. Freehand:
By using the Freehand Tool, lines can be directly drawn with the mouse (or
other drawing input sources like drawing tables). Blanked points are automatically
added to the start and the end point of the freehand line.
This tool was developed to allow for the creation of complex figures, e.g. if pictures
shall be redrawn. Easiest use is with a drawing tablet.
A click with the right mouse button opens a dialog (Fig. 37Fig. 37: Figure
Editor/Painting Tools/Freehand: Dialog to set up freehand parameters.) for setting the
tool specifications. The drawing type can be specified (corner-, line- or circle-points)
as well as the distance- or time value for the drawing of the points.
Left mouse button, right mouse button:
These values refer either to distance if drawing is made with clicked left mouse
button, or to time, if drawing is done with clicked right mouse button.
6.2.12. Bezier:
Bezier curves can be describes as “bent lines”. This is quite a mighty feature,
however it requires the user’s capability to imagine how the initial drawn line modifies
to the bent curve.
A Bezier curve consists of a drawn line and two control lines. Both control lines are
used for “bending” the drawn line – this can happen in four coordinates.
The two control lines are shown in red, where the drawn line appears in the selected
color. Of course the control lines are not visible in the figure, but are needed for
proper drawing.
