[][src]Struct footile::Transform

pub struct Transform { /* fields omitted */ }

An affine transform can translate, scale, rotate and skew 2D points.

A series of transforms can be combined into a single Transform struct. This can be used by a Plotter to alter subsequent points.

Example

use footile::Transform;
const PI: f32 = std::f32::consts::PI;
let t = Transform::new_translate(-50.0, -50.0)
    .rotate(PI)
    .translate(50.0, 50.0)
    .scale(2.0, 2.0);

Methods

impl Transform[src]

pub fn new() -> Self[src]

Create a new identity transform.

pub fn new_translate(tx: f32, ty: f32) -> Self[src]

Create a new translation transform.

  • tx Amount to translate X.
  • ty Amount to translate Y.

pub fn new_scale(sx: f32, sy: f32) -> Self[src]

Create a new scale transform.

  • sx Scale factor for X dimension.
  • sy Scale factor for Y dimension.

pub fn new_rotate(th: f32) -> Self[src]

Create a new rotation transform.

  • th Angle to rotate coordinates (radians).

pub fn new_skew(ax: f32, ay: f32) -> Self[src]

Create a new skew transform.

  • ax Angle to skew X-axis (radians).
  • ay Angle to skew Y-axis (radians).

pub fn translate(self, tx: f32, ty: f32) -> Self[src]

Apply translation to a transform.

  • tx Amount to translate X.
  • ty Amount to translate Y.

pub fn scale(self, sx: f32, sy: f32) -> Self[src]

Apply scaling to a transform.

  • sx Scale factor for X dimension.
  • sy Scale factor for Y dimension.

pub fn rotate(self, th: f32) -> Self[src]

Apply rotation to a transform.

  • th Angle to rotate coordinates (radians).

pub fn skew(self, ax: f32, ay: f32) -> Self[src]

Apply skew to a transform.

  • ax Angle to skew X-axis (radians).
  • ay Angle to skew Y-axis (radians).
