Hi,

from the Wiki https://wiki.synfig.org/Scale_Layer

A “Scale Layer” scales the size of any primitive layers (regions, gradients, etc.) below it. “Scale Layer” is part of Transform Layers category.

## Parameters of Scale Layers

The parameters of the Scale Layers are:

The Amount parameter may take the inverse of the exponential function (the natural log), as a raw value. For example:

- the natural log of 2.00 is 0.693147181, which up-scales to 200.0%
- the natural log of 1.00 is 0.0, which scales by 0.0%
- the natural log of 0.50 is -0.693147181, which down-scales to 50.0%
- the natural log of 0.10 is -2.302585092994045, which down-scales to 10.0%
- the natural log of 0.01 is -4.605170185988091, which down-scales to 1.0%
The Origin is the center of the scale.

Who was pervert enough to implement Amount as a Logarithm?

Like always, you could use a wrapping Group Layer instead (property Transform-Scale, the value is in Synfig units of 60px)

or you can use a converter on Amount from the Scale Layer:

- Right-click on Amount
- Convert / Logarithm
- Expand Amount and set Link parameter as scale factor

thank you bobsynfig, i got it
