Methods

`Protected` _drawImage

_drawImage(ex: ExcaliburGraphicsContext, x: number, y: number): void
Meant to be overridden by the graphic implementation to draw the underlying image (HTMLCanvasElement or HTMLImageElement) to the graphics context without transform. Transformations like position, rotation, and scale are handled by Graphic._preDraw and Graphic._postDraw
Parameters
- ex: ExcaliburGraphicsContext
  
  The excalibur graphics context
- x: number
- y: number
Returns void
Overrides Graphic._drawImage
- Defined in Graphics/SpriteFont.ts:106

`Protected` _flip

_flip(ex: AffineMatrix | ExcaliburGraphicsContext): void
Parameters
- ex: AffineMatrix | ExcaliburGraphicsContext
Returns void
Inherited from Graphic._flip
- Defined in Graphics/Graphic.ts:261

`Protected` _postDraw

_postDraw(ex: ExcaliburGraphicsContext): void
Apply any additional work after Graphic._drawImage and restore the context state.
Parameters
- ex: ExcaliburGraphicsContext
Returns void
Inherited from Graphic._postDraw
- Defined in Graphics/Graphic.ts:277

`Protected` _preDraw

_preDraw(ex: ExcaliburGraphicsContext, x: number, y: number): void
Apply affine transformations to the graphics context to manipulate the graphic before Graphic._drawImage
Parameters
- ex: ExcaliburGraphicsContext
- x: number
- y: number
Returns void
Inherited from Graphic._preDraw
- Defined in Graphics/Graphic.ts:232

`Protected` _rotate

_rotate(ex: AffineMatrix | ExcaliburGraphicsContext): void
Parameters
- ex: AffineMatrix | ExcaliburGraphicsContext
Returns void
Inherited from Graphic._rotate
- Defined in Graphics/Graphic.ts:250

clone

clone(): SpriteFont
Returns a new instance of the graphic that has the same properties

Returns SpriteFont
Overrides Graphic.clone
- Defined in Graphics/SpriteFont.ts:139
