runBackend #

Arguments

:: (Backend b V2 (N b), Renderable (Path V2 (N b)) b, TypeableFloat (N b), Metric (V b)) 
=> DEnv (N b)

Environment to start rendering with.

-> BackendProgram a

Chart render code.

-> (QDiagram b V2 (N b) Any, a)

The diagram.

Run this backends renderer.

runBackendR #

Arguments

:: (Backend b V2 (N b), Renderable (Path V2 (N b)) b, TypeableFloat (N b), Metric (V b)) 
=> DEnv (N b)

Environment to start rendering with.

-> Renderable a

Chart render code.

-> (QDiagram b V2 (N b) Any, PickFn a)

The diagram.

Run this backends renderer.

runBackendWithGlyphs #

Arguments

:: (Backend b V2 (N b), Renderable (Path V2 (N b)) b, Renderable (Text (N b)) b, TypeableFloat (N b), Metric (V b)) 
=> DEnv (N b)

Environment to start rendering with.

-> BackendProgram a

Chart render code.

-> (QDiagram b V2 (N b) Any, a, Map (String, FontSlant, FontWeight) (Set String)) 

Run this backends renderer.

defaultEnv #

Arguments

:: (Read n, RealFloat n) 
=> AlignmentFns

Alignment functions to use.

-> n

The output image width in backend coordinates.

-> n

The output image height in backend coordinates.

-> IO (DEnv n) 

Produce a default environment with just the sans-serif fonts.

createEnv #

Arguments

:: (Read n, RealFloat n) 
=> AlignmentFns

Alignment functions to use.

-> n

The output image width in backend coordinates.

-> n

The output image height in backend coordinates.

-> FontSelector n 
-> DEnv n 

Produce an environment with a custom set of fonts. The defult fonts are still loaded as fall back.

data DEnv n #

The diagrams backend environement.

Constructors

DEnv 

Fields

File Output Functons

data FileFormat #

The file output format: EPS -> Embedded Postscript SVG -> SVG with text rendered as stroked paths SVG -> SVG with embedded font information and text rendered as text operations

Constructors

EPS 
SVG 
SVG_EMBEDDED 

renderableToFile :: FileOptions -> FilePath -> Renderable a -> IO (PickFn a) #

Generate an image file for the given renderable, at the specified path. Size, format, and text rendering mode are all set through the FileOptions parameter.

toFile :: (Default r, ToRenderable r) => FileOptions -> FilePath -> EC r () -> IO () #

Generate an image file from from the state content of an EC computation. The state may have any type that is an instance of ToRenderable

cBackendToFile :: FileOptions -> BackendProgram a -> FilePath -> IO a #

Generate an image file for the given drawing instructions, at the specified path. Size and format are set through the FileOptions parameter.

Fonts

loadSansSerifFonts :: forall n. (RealFloat n, Read n) => IO (FontSelector n) #

Load sans-serif fonts only

loadCommonFonts :: forall n. (RealFloat n, Read n) => IO (FontSelector n) #

Load serif, sans-serif and monospace fonts.
