CanvasViewportTransform class

Transform for drawing using a canvas context. Y-flip is permanently set to true.

Inheritance

Constructors

CanvasViewportTransform(Vector2 extents, Vector2 center): Constructs a new viewport transform with the default scale.

center → Vector2: center of the viewport.
finalinherited
extents → Vector2: This is the half-width and half-height. This should be the actual half-width and half-height, not anything transformed or scaled.
finalinherited
hashCode → int: The hash code for this object.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
scale ↔ double: Returns the scaling factor used in converting from world sizes to rendering sizes.
getter/setter pairinherited
translation ↔ Vector2: The current translation is the difference in canvas units between the actual center of the canvas and the currently specified center. For example, if the actual canvas center is (5, 5) but the current center is (6, 6), the translation is (1, 1).
getter/setter pairinherited
yFlip ↔ bool: if we flip the y axis when transforming.

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
screenToWorld(Vector2 argScreen) → Vector2: Takes the screen coordinates and return the corresponding world coordinates.
inherited
setCamera(double x, double y, double s) → void: Sets the transform's center to the given x and y coordinates, and using the given scale.
inherited
toString() → String: A string representation of this object.
inherited
updateTransformation(CanvasRenderingContext2D ctx) → void: Sets the rendering context such that all drawing commands given in terms of the world coordinate system will display correctly on the canvas screen.
worldToScreen(Vector2 argWorld) → Vector2: Takes the world coordinates and return the corresponding screen coordinates.
