Package: Matrix

Description

package Pango.Matrix is
A structure specifying a transformation between user-space coordinates 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;
