Declaration [src]

void
pango_matrix_get_font_scale_factors (
  const PangoMatrix* matrix,
  double* xscale,
  double* yscale
)

Description [src]

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.
