Struct gegl::Matrix3

#[repr(transparent)]
pub struct Matrix3 { /* private fields */ }

GLib type: Boxed type with copy-on-clone semantics.

Implementations

impl Matrix3

pub fn as_ptr(&self) -> *mut GeglMatrix3

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GeglMatrix3) -> &Self

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut(ptr: &mut *mut GeglMatrix3) -> &mut Self

Borrows the underlying C value mutably.

impl Matrix3

pub fn new() -> Matrix3

Returns

A newly allocated Matrix3

pub fn copy_into(&mut self, src: &Matrix3)

Copies the matrix in src into self.

src

a Matrix3

pub fn determinant(&self) -> f64

Returns the determinant for the matrix.

pub fn identity(&mut self)

Set the provided self to the identity matrix.

pub fn invert(&mut self)

Inverts self.

pub fn is_affine(&self) -> bool

Check if a matrix only does an affine transformation.

Returns TRUE if the matrix only does an affine transformation.

pub fn is_identity(&self) -> bool

Check if a matrix is the identity matrix.

Returns TRUE if the matrix is the identity matrix.

pub fn is_scale(&self) -> bool

Check if a matrix only does scaling.

Returns TRUE if the matrix only does scaling.

pub fn is_translate(&self) -> bool

Check if a matrix only does translation.

Returns TRUE if the matrix only does trasnlation.

pub fn multiply(&self, right: &Matrix3, product: &mut Matrix3)

Multiples product = self · right

right

a Matrix3

product

a Matrix3 to store the result in.

pub fn originate(&mut self, x: f64, y: f64)

Shift the origin of the transformation specified by self to (x, y). In other words, calculate the matrix that:

1. Translates the input by (-x, -y).

2. Transforms the result using the original self.

3. Translates the result by (x, y).

x

x coordinate of new origin

y

y coordinate of new origin.

pub fn parse_string(&mut self, string: &str)

Parse a transofmation matrix from a string.

string

a string describing the matrix (right now a small subset of the transform strings allowed by SVG)

pub fn round_error(&mut self)

Rounds numerical errors in self to the nearest integer.
