struct Pango::Matrix

• Pango::Matrix
• Struct
• Value
• Object

Overview

A Pango::Matrix 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.cr
