Graphics Features 6.2.
Drawings in Laserworld Showeditor are vector-graphics. This means, that pictures are
drawn from one point to the next one. Normal, visible points are set with a left mouse
click, where blanked, invisible points are set with right mouse click.
The tools for drawing figures (already explained in chapter 4.1) are shown in Fig.25.
Detailed explanation of each drawing option:
6.2.1. New Figure:
This creates a completely new figure
6.2.2. UNDO:
“UNDO” of previous action. This makes the figure return to the state it had
one step back. Providing the undo-option can be resource-intense for the computer,
especially if large ILDA figures are handled, so this feature can be switched off in
Options -> Others1.
Important to know about the behaviour of the UNDO feature:
Example: Ellipse is selected. 4 ellipses are drawn. Then rectangle is selected and 4
rectangles are drawn. If assuming, that the last rectangle was not placed correctly
and “UNDO” is used, then ALL 4 rectangles are “un-done” - not only the last one!
So the undo feature applies to all consequent uses of the specific drawing tool.
6.2.3. REDO:
If “REDO” is clicked, the program returns to the version of the figure, as it
was before the click on “UNDO”.
6.2.4. Poly-Line:
This tool allows for creating connected lines. Every click created a point which is
automatically linked to the previous point by a line.
Left-click creates a visible point, right click creates an invisible (blanked) point.
A blanked point is automatically set at the position where the drawing starts at first,
before the first visible point. To draw two single lines with this tool, a blanked point has
to be set at the start point of the second line prior to setting the visible point, so the
scanner of the laser system knows where to move without outputting laser light
(blanked).
Blanked lines / points are important, as they are used to tell the scanners what
position they should move to start drawing the next points. It is essential to
understand that every picture that is displayed with a show laser system is created by
very fast repeated drawing of one single laser beam – comparable to a pen, that
