Methods

impl Form

fn shift(self, x: f64, y: f64) -> Form

Move a form by the given amount. this is a relative translation so shift(10.0, 10.0, form) would moveform` ten pixels up and ten pixels to the right.

fn shift_x(self, x: f64) -> Form

Move a shape in the x direction. This is relative so shift_x(10.0, form) moves form 10 pixels to the right.

fn shift_y(self, y: f64) -> Form

Move a shape in the y direction. This is relative so shift_y(10.0, form) moves `form upwards by 10 pixels.

fn scale(self, scale: f64) -> Form

Scale a form by a given factor. Scaling by 2 doubles both dimensions and quadruples the area.

fn rotate(self, theta: f64) -> Form

Rotate a form by a given angle. Rotate takes radians and turns things counterclockwise. So to turn form 30 degrees to the left you would say rotate(degrees(30), form).

fn alpha(self, alpha: f32) -> Form

Set the alpha of a Form. The default is 1 and 0 is totally transparent.
