class Pango::Matrix
- Pango::Matrix
- Reference
- Object
Overview
A PangoMatrix specifies a transformation between user-space
and device coordinates.
The transformation is given by
x_device = x_user * matrix->xx + y_user * matrix->xy + matrix->x0;
y_device = x_user * matrix->yx + y_user * matrix->yy + matrix->y0;Defined in:
lib/gi-crystal/src/auto/pango-1.0/matrix.crConstructors
