scale abstract method

double scale(
  1. double fontSize
)

Computes the scaled font size (in logical pixels) with the given unscaled fontSize (in logical pixels).

The input fontSize must be finite and non-negative.

When given the same fontSize input, this method returns the same value. The output of a larger input fontSize is typically larger than that of a smaller input, but on unusual occasions they may produce the same output. For example, some platforms use single-precision floats to represent font sizes, as a result of truncation two different unscaled font sizes can be scaled to the same value.

Implementation

double scale(double fontSize);
