Method
Pango.Matrix.get_font_scale_factors
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.
