psMat¶
-
psMat.identity()¶ returns an identity matrix as a 6 element tuple
-
psMat.compose(mat1, mat2)¶ returns a matrix which is the composition of the two input transformations
-
psMat.inverse(mat)¶ returns a matrix which is the inverse of the input transformation. (Note: There will not always be an inverse)
-
psMat.rotate(theta)¶ returns a matrix which will rotate by
theta.thetais expressed in radians
-
psMat.scale(x[, y])¶ returns a matrix which will scale by
xin the horizontal direction andyin the vertical. Ifyis omitted, it will scale by the same amount (x) in both directions
-
psMat.skew(theta)¶ returns a matrix which will skew by
theta(to produce an oblique font).thetais expressed in radians
-
psMat.translate(x, y)¶ returns a matrix which will translate by
xin the horizontal direction andyin the vertical
