data Figure

Figure type carries a texture, sizing information and rotation information.

Constructors

Instances

Rendering Figure MiniLight

Defined in MiniLight.Figure

Methods

translate :: V2 Int -> Figure -> Figure

clip :: Rectangle Int -> Figure -> Figure

rotate :: Double -> Figure -> Figure

text :: Font -> V4 Word8 -> Text -> MiniLight Figure

picture :: FilePath -> MiniLight Figure

fromTexture :: Texture -> MiniLight Figure

rectangleOutline :: V4 Word8 -> V2 Int -> MiniLight Figure

rectangleFilled :: V4 Word8 -> V2 Int -> MiniLight Figure

triangleOutline :: V4 Word8 -> V2 Int -> MiniLight Figure

emptyFigure :: Figure

A figure which has no texture. You can render it but do nothing.

getFigureSize :: Figure -> V2 Int

freeFigure :: MonadIO m => Figure -> m ()

union :: Rectangle Int -> Rectangle Int -> Rectangle Int

render :: (HasLightEnv env, MonadIO m, MonadMask m) => Figure -> LightT env m ()

Render a figure.

renders :: (HasLightEnv env, MonadIO m, MonadMask m) => [Figure] -> LightT env m ()

Render figures.

withBlendedText :: (MonadIO m, MonadMask m) => Font -> Text -> Color -> (Surface -> m a) -> m a

class Rendering r m | r -> m where

Rendering typeclass provides basic operations for figures.

Methods

translate :: V2 Int -> r -> r

Change the place to be rendered.

clip :: Rectangle Int -> r -> r

Specify some area and clip the figure into the region.

rotate :: Double -> r -> r

Rotate a figure.

text :: Font -> V4 Word8 -> Text -> m r

Create a text texture. Be careful: this is a slow operation, use cache as long as you can.

picture :: FilePath -> m r

Create a texture from a png file. Be careful: this is a slow operation, use cache as long as you can.

fromTexture :: Texture -> m r

Create a texture from a raw SDL texture.

rectangleOutline

Arguments

:: V4 Word8

Stroke color

-> V2 Int

Size

-> m r

Create an outlined rectangle. Be careful: this is a slow operation, use cache as long as you can.

rectangleFilled

Arguments

:: V4 Word8

Filling color

-> V2 Int

Size

-> m r

Create a filled texture. Be careful: this is a slow operation, use cache as long as you can.

triangleOutline

Arguments

:: V4 Word8

Stroke color

-> V2 Int

Size

-> m r

Create an outlined triangle. Be careful: this is a slow operation, use cache as long as you can.
