drawPicture :: forall sprite. Context2D -> (sprite -> Maybe CanvasImageSource) -> Picture sprite -> Aff Unit

Draw a picture It is not recommended to use this except for the glapple system.

tryLoadImageAff :: String -> Aff CanvasImageSource

Aff version of tryLoadImage

transform :: forall s. Transform -> Picture s -> Picture s

absorb' :: forall s. (Context2D -> (s -> Maybe CanvasImageSource) -> Aff (Picture s)) -> Picture s

It is not recommended to use this system except for the glapple system.

empty :: forall sprite. Picture sprite

Empty picture.

rotate :: forall s. Number -> Picture s -> Picture s

Rotate a picture. (Clockwise)

absolute :: forall s. Picture s -> Picture s

Disables the parent's transform, forcing it to draw from the origin. Heavy use is deprecated.

arc :: forall s. { angle :: Number, radius :: Number, start :: Number } -> Picture s

Draw an arc with stroke. Property angle is the rotation angle from the start position. A positive number will cause a clockwise rotation, 2π will make a perfect circle, and 4π will return to a blank state.

addComposite :: forall s. Picture s -> Picture s -> Picture s

color :: forall s. Color -> Picture s -> Picture s

Set color

destinationOverComposite :: forall s. Picture s -> Picture s -> Picture s

drawWithTransform :: forall s. (Transform -> Picture s) -> Picture s

Retrieves the current transform state and draws a Picture.

fan :: forall s. Shape -> { angle :: Number, radius :: Number, start :: Number } -> Picture s

Draw a fan. Property angle is the rotation angle from the start position. A positive number will cause a clockwise rotation, 2π will make a perfect circle, and 4π will return to a blank state.

font :: forall s. Font -> Picture s -> Picture s

Set font.

line :: forall sprite. Array (Number /\ Number) -> Picture sprite

Draw line.

lineWidth :: forall s. Number -> Picture s -> Picture s

Set lineWidth.

multiplyComposite :: forall s. Picture s -> Picture s -> Picture s

opacity :: forall s. Number -> Picture s -> Picture s

Set opacity.

polygon :: forall sprite. Shape -> Array (Number /\ Number) -> Picture sprite

Draw polygon.

rect :: forall s. Shape -> Number -> Number -> Picture s

Draw rectangle.

scale :: forall s. Number -> Number -> Picture s -> Picture s

Scale a picture.

sourceOverComposite :: forall s. Picture s -> Picture s -> Picture s

sprite :: forall sprite. sprite -> Picture sprite

Draws the sprite loaded by runGame.

text :: forall sprite. Shape -> String -> Picture sprite

Draw text.

textAlign :: forall s. TextAlign -> Picture s -> Picture s

Set textAlign.

textBaseLine :: forall s. TextBaseline -> Picture s -> Picture s

Set textBaseLine.

translate :: forall s. Number -> Number -> Picture s -> Picture s

Translate a picture.

paint :: forall s. DrawStyle s -> Picture s -> Picture s

Add color or pattern.

absorb :: forall s. Aff (Picture s) -> Picture s

Embeds the action of Aff into the Picture.
