yes, had also this idea. But I use now a scale slider as multiplier, this works better.

Yes, it’s not woking. I use the height value to calculate the ratio and then it will changed in the next line at the same time. 😐

Oh this is a bit embarrassing, better I read the documentation more thorough.

Lot of thanks.🧐

I tried now to realize your idea in this feed from April 8, 2007.

I iterate through the path and collect all min and max values.

myPath = thisComp.layer("Shape Layer 1").mask("Mask 1").maskPath.points();
xValues = [];
yValues = [];
for (i in myPath){
	xValues.push(myPath[i][0]);
	yValues.push(myPath[i][1]);
};
width = Math.max(...yValues) - Math.min(...yValues);
height = Math.max(...xValues) - Math.min(...xValues);
left = Math.min(...xValues);
top = Math.min(...yValues);

Hello Friends,

I’m also looking to get the bounding box size of a mask.

Anybody here how found an elegant solution/expression for this?

Thanks

Hi Andrei,

lot of thanks for your reply.

I also came on a similar result after I post that. But I start first to turn the values in seconds.

I think your calculation hold a frame 3 frames long. Its not really a frame rate Frames/Sec.

I the end I think this is good and short result .

fRate = 6;
fps = 1/thisComp.frameDuration;
fRateSec = framesToTime(fps/fRate, fps);
pt = fRateSec*Math.floor(time/fRateSec);
a = linear(pt, inPoint, outPoint, [0,0], [500,0]);

b = linear(time, inPoint, outPoint, [0,0], [0,200]);
position + a + b;
