First load a picture by using the button “Load Picture”. Then click on “Trace Image”
to start the tracing. With the tracing the system tries to automatically convert the
pixel image to a vector graphics.
To avoid getting a flickering projection later, it is recommended to not exceed a limit
of 2000 points in total for a 30kpps Galvo system.
The number of “trace points” can be controlled with the four scrollbars: Moving them
to the right means “more points”, to the left means “fewer points”.
The challenge is to find the ideal setting with as few points a possible but still
achieving a good result.
It is helpful if the image that shall be converted has a width of about 800px and any
unnecessary parts should have been already deleted with graphics software prior to
tracing.
If the converted result is acceptable and shall be imported, a click on “Apply to
figure” creates the respective figure in the drawing area of the Figure Editor.
6.18.12. Tool: Color Shove
The Color Shove tool creates a multi-frame animated figure from a single frame by
animating the colors of the figure: The different colors are shoved through the figure
point by point (one point per frame), so the figure gets kind of a color sparkling
effect – but only with the colors it consists of.
Example of how this tool works:
A triangle is given – side 1 is red, side 2 is green and side 3 is blue. In total there are 3
colors (4, if the blanked points are respected). When applying the Color Shove, a
new figure is created consisting of 3 (4) frames. The triangle shape remains the same,
but on each change of a frame, the respective color moves on by one point. So the
sides of the triangle change their color by every frame change.
This of course also works with more complex graphics. As the tool only uses the colors
already present in the figure, the animation created by the Color Shove looks
homogenous and matches the general color set.
The Color Shove Tool also works for multi frame figures, but only the colors of the first
frame are shifted. For the following frames the original x/y coordinates of the
animation stay the same, but the colors set from the first frame is pushed through.
Due to this it is necessary that the number of points should be the same per frame,
otherwise the software needs to interpolate points that are missing – which may lead
to unwanted results.
Hint:
To decrease the distance between points, it is recommended to use the “Opt.
Distance” tool. (See chapter 6.3.6 and especially 7, shown in Fig. 77).
Important:
For using the tool, an already existing and saved figure is needed.
Remember to save all changes to an existing figure prior to applying this tool!
