pub struct Camera {
pub offset: Vec2,
pub zoom: f64,
pub min_zoom: f64,
pub max_zoom: f64,
}Expand description
Camera manages the view transform for the canvas.
It handles panning (translation) and zooming (scaling) operations, converting between screen coordinates and world coordinates.
Fields§
§offset: Vec2Current translation offset (pan)
zoom: f64Current zoom level (BASE_ZOOM = 100% in UI)
min_zoom: f64Minimum allowed zoom level
max_zoom: f64Maximum allowed zoom level
Implementations§
Source§impl Camera
impl Camera
Sourcepub fn transform(&self) -> Affine
pub fn transform(&self) -> Affine
Get the affine transform for rendering.
This transform converts world coordinates to screen coordinates.
Sourcepub fn inverse_transform(&self) -> Affine
pub fn inverse_transform(&self) -> Affine
Get the inverse transform for input handling.
This transform converts screen coordinates to world coordinates.
Sourcepub fn screen_to_world(&self, screen_point: Point) -> Point
pub fn screen_to_world(&self, screen_point: Point) -> Point
Convert a screen point to world coordinates.
Sourcepub fn world_to_screen(&self, world_point: Point) -> Point
pub fn world_to_screen(&self, world_point: Point) -> Point
Convert a world point to screen coordinates.
Sourcepub fn zoom_at(&mut self, screen_point: Point, factor: f64)
pub fn zoom_at(&mut self, screen_point: Point, factor: f64)
Zoom the camera, keeping the given screen point fixed.
Sourcepub fn fit_to_bounds(&mut self, bounds: Rect, viewport: Size, padding: f64)
pub fn fit_to_bounds(&mut self, bounds: Rect, viewport: Size, padding: f64)
Fit the camera to show the given bounding box.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
