A rectangle consists of 4 corner points and the lines between them. A Galvo scanner
system is, without optimization, not able to simply project these 4 coordinates,
because of its resonances and its physically given inertia (mainly of the mirrors that
need to move very very fast. The bigger and heavier the mirrors are, the higher is the
inertia). Too slow Galvo scanners are not able to display the corners correctly. The
rectangle then becomes something like a circle. Too fast Galvo scanners fast mainly
display the corner points, but the lines are missing or too less intense. Thus it is
necessary to optimize the ways of movement for each Galvo system. The
optimization “interpolates” the 4 lines between the corners – which means that the
lines are virtually split to small pieces. The corner points are repeated several times for
an intense and precise projection. The number of small line peaches necessary and
of the corner repetitions depends on the Galvo scanner system.
For these kind of optimizations the term “properties of points” applies: line points
have other properties than corner points. Each element (circle, square, letters etc.)
has its own properties.
In order for Laserworld Showeditor to understanding how to work with the respective
points and lines, each point has certain properties. These properties define how to
optimize the output for the very Galvo scanner system.
6.3.7. Pipette (copy color):
If colors of one point shall be used for another point, the Pipette tool is used.
First select the desired points where the color should be picked up, and then click on
the pipette tool icon. By selecting other points of the figure, they get the same color
as the original point(s).
6.3.8. Magnifying Glass:
The magnifying glass tool is used for zooming-in to the drawing area. This allows
for much more detailed work, as it can zoom down to the very pixel.
Hint:
If the Grid size is set to 0, the frames can be drawn exact by pixel.
There are several ways for using the magnifying glass:
A) Select the magnifying glass and select an area with clicked left mouse button.
The selected area is displayed magnified. The marked region is stretched to fit
the drawing area. Thus distortions may occur.
B) Select the magnifying glass and move the mouse cursor to the point where
the magnification is needed. Use the mouse wheel for zooming.
When a zoom is set, the frame can be reset to normal 100% view by left-clicking on
the magnifying glass icon again. With a right click on the icon, it is just re-selected
and the click does not affect the current zoom level.
