Implementations
impl GeomBatch
[src]
pub fn new() -> GeomBatch
[src]
Creates an empty batch.
pub fn from(list: Vec<(Color, Polygon)>) -> GeomBatch
[src]
Creates a batch of colored polygons.
pub fn push(&mut self, color: Color, p: Polygon)
[src]
Adds a single colored polygon.
pub fn fancy_push(&mut self, color: FancyColor, p: Polygon)
[src]
pub fn extend(&mut self, color: Color, polys: Vec<Polygon>)
[src]
Applies one color to many polygons.
pub fn append(&mut self, other: GeomBatch)
[src]
Appends all colored polygons from another batch to the current one.
pub fn consume(self) -> Vec<(FancyColor, Polygon)>
[src]
Returns the colored polygons in this batch, destroying the batch.
pub fn draw(self, g: &mut GfxCtx)
[src]
Draws the batch, consuming it. Only use this for drawing things once.
pub fn upload(self, ctx: &EventCtx) -> Drawable
[src]
Upload the batch of polygons to the GPU, returning something that can be cheaply redrawn many times later.
pub fn batch(self) -> Widget
[src]
Wrap in a Widget for layouting, so this batch can become part of a larger one.
pub fn to_btn(self, ctx: &EventCtx) -> BtnBuilder
[src]
Turn this batch into a button.
pub fn get_bounds(&self) -> Bounds
[src]
Compute the bounds of all polygons in this batch.
pub fn autocrop(self) -> GeomBatch
[src]
Sets the top-left to 0, 0. Not sure exactly when this should be used.
pub fn unioned_polygon(&self) -> Polygon
[src]
Builds a single polygon covering everything in this batch. Use to create a hitbox.
pub fn get_dims(&self) -> ScreenDims
[src]
Returns the width and height of all geometry contained in the batch.
pub fn from_svg_contents(raw: Vec<u8>) -> GeomBatch
[src]
Returns a batch containing a parsed SVG string.
pub fn load_svg(prerender: &Prerender, filename: &str) -> GeomBatch
[src]
Returns a batch containing an SVG from a file.
pub fn color(self, transformation: RewriteColor) -> GeomBatch
[src]
Transforms all colors in a batch.
pub fn centered_on(self, center: Pt2D) -> GeomBatch
[src]
Translates the batch to be centered on some point.
pub fn translate(self, dx: f64, dy: f64) -> GeomBatch
[src]
Translates the batch by some offset.
pub fn rotate(self, angle: Angle) -> GeomBatch
[src]
Rotates each polygon in the batch relative to the center of that polygon.
pub fn rotate_around_batch_center(self, angle: Angle) -> GeomBatch
[src]
Rotates each polygon in the batch relative to the center of the entire batch.
pub fn scale(self, factor: f64) -> GeomBatch
[src]
Scales the batch by some factor.
