Math.round for Shape layers to land on whole pixels?

Question

Trying to keep my shape layers on whole pixels to avoid subpixel blurring.

For one-dimensional properties, this works fine:

Math.round(value);

But for two dimensional props, I'm running into errors with things like this:

temp = Math.round(content("Rectangle 1").content("Rectangle Path 1").size.value)

(temp[0],temp[1])

temp = Math.round(content("Rectangle 1").content("Rectangle Path 1").size)

(temp[0],temp[1])

I'm sure my syntax is off. Properties in arrays always give me problems. Can you help?

Your expression works perfectly for Shape Layer size. But when I alter it for Transform>Position, I get a "class Global has no property named 'temp' error.

Isn't Postion an array like Shape Layer>Size?

temp = thisComp.layer("Shape Layer 1").transform.position.value

[Math.round(temp[0]),Math.round(temp[1])]

Is it possible to construct a more general purpose expression by using temp = value without having to use thisComp.layer("layername").etc?

You're just missing a semi-colon at the end of the first line.

In answer to your second question, yes--in fact this will work:

[Math.round(value[0]),Math.round(value[1])]

Math.round() won't work with an array, so you need to use it twice, like this(Math.round(temp[0]),Math.round(temp[1]))Dan
