NVGMatrix

identity NVGMatrix identity(): Sets this matrix to identity matrix.
invert NVGMatrix invert(): Inverts this matrix. If inverted matrix cannot be calculated, this.valid fill be false.
inverted NVGMatrix inverted(): Returns new inverse matrix. If inverted matrix cannot be calculated, res.valid fill be false.
mul NVGMatrix mul(NVGMatrix s): Sets this matrix to the result of multiplication of this and s (this * S).
opBinary NVGMatrix opBinary(NVGMatrix s): Multiply this matrix by s, return result as new matrix. Performs operations in this left-to-right order.
opOpAssign NVGMatrix opOpAssign(NVGMatrix s): Multiply this matrix by s. Performs operations in this left-to-right order.
point void point(float* dx, float* dy, float sx, float sy): Transform point with this matrix. null destinations are allowed. sx and sy is the source point. dx and dy may point to the same variables.
point void point(float x, float y): Transform point with this matrix.
premul NVGMatrix premul(NVGMatrix s): Sets this matrix to the result of multiplication of s and this (S * this). Sets the transform to the result of multiplication of two transforms, of A = B*A.
rotate NVGMatrix rotate(float a): Rotate this matrix.
rotateTransform NVGMatrix rotateTransform(float a, float tx, float ty): This is the same as doing: mat.identity.rotate(a).translate(tx, ty), only faster
scale NVGMatrix scale(float sx, float sy): Scale this matrix.
scaleRotateTransform NVGMatrix scaleRotateTransform(float xscale, float yscale, float a, float tx, float ty): Utility function to be used in setXXX(). This is the same as doing: mat.identity.rotate(a).scale(xs, ys).translate(tx, ty), only faster
skewX NVGMatrix skewX(float a): Skew this matrix by X axis.
skewY NVGMatrix skewY(float a): Skew this matrix by Y axis.
skewY NVGMatrix skewY(float ax, float ay): Skew this matrix by both axes.
translate NVGMatrix translate(float tx, float ty): Translate this matrix.

Properties

isIdentity bool isIdentity [@property getter]: Returns true if this matrix is identity matrix.
valid bool valid [@property getter]: Can be used to check validity of inverted result
