Cant Move Pivot point

Hello,

After i imported a SVG file i notice that the pivot point of the Circle are all in the center of the composition.
I will like to move the pivot point of each circle (Polygon) at the center of the circle, but i cant find out how to do it.
In the forum somebody suggest to press M when drag the pivot but is not working.
Some Suggestion

Having the same question. It doesn't seem to be possible the way the importer is build now. I've tried to add a transform on a part inside the svg group in Fusion, but that destroys the masking.

Unfortunately, the Polygon node doesn't have a Pivot control, so you'll have to use a Transform. The reason it destroys the masking is because only a single-channel Mask tool can plug into another Mask tool. When you add the Transform, it promotes the image to four-channel RGBA. The trick is to put a Bitmap node behind the Transform, which will strip away the RGB channels, allowing you to plug into the next node as before.

So you'll have your original Polygon from the SVG import -> Transform -> Bitmap -> Next tool

You can then move the Pivot of the Transform to wherever you need it to go.

Moving the Center of a Polygon without moving the spline itself is an interesting problem, though. I think it can be scripted; I'll see if I can't bash something together.

I thought there was a right-click and/or shortcut and/or script for that already somewhere.
I'll see if I can find it.

If you can, that would save me a few hours!

Hold down 'm' while dragging the center will do this. It has been this way since at least 2013, because that's where I found it in my old Fusionlist archive.

You can relax now, Bryan.

Brilliant!

But if anyone should want to get the average of a polyline's points:

Code: Select all

points = tool:GetBezierPolyline(comp.CurrentTime).Value.Points
x = 0
y = 0

for i, pt in ipairs(points) do
    x = x + pt.X
    y = y + pt.Y
end

x = x + 0.5
y = y + 0.5
x = x/table.getn(points)
y = y/table.getn(points)

Before i started this post I tried and tried again to press [m] while dragging but was not working.
Now yes is working, why i dont know.

Hi Bryan, how i can execute the below code.

Code: Select all

points = tool:GetBezierPolyline[comp.CurrentTime].Value.Points
x = 0
y = 0

for i, pt in ipairs(points) do
    x = x + pt.X
    y = y + pt.Y
end

x = x + 0.5
y = y + 0.5
x = x/table.getn(points)
y = y/table.getn(points)


Well, first you'd need to fix my syntax error. In the first line, I used square brackets where I needed parentheses. This is correct:

Code: Select all

points = tool:GetBezierPolyline(comp.CurrentTime).Value.Points
x = 0
y = 0

for i, pt in ipairs(points) do
    x = x + pt.X
    y = y + pt.Y
end

x = x + 0.5
y = y + 0.5
x = x/table.getn(points)
y = y/table.getn(points)


Assuming you have a Polygon tool in your comp called 'tool', you could just paste it into the Console. The variables x and y would then hold the coordinates for the geometric center of the polyline. But in this form, the code isn't very useful. It's just a fragment in case somebody else came along and wanted to use it as a starting point.
