Matrix.getFontScaleFactors

void getFontScaleFactors(out double xscale, out double yscale)

Calculates the scale factor of a matrix on the width and height of the font.

That is, xscale is the scale factor in the direction of the X coordinate, and yscale is the scale factor in the direction perpendicular to the vector that the X coordinate is mapped to.

Note that output numbers will always be non-negative.

Parameters

`xscale`	output scale factor in the x direction
`yscale`	output scale factor perpendicular to the x direction
