Description

PDF Shapes

Synopsis

Shapes

Paths

moveto :: Point -> Draw () Source #

Move pen to a given point without drawing anything

lineto :: Point -> Draw () Source #

Draw a line from current point to the one specified by lineto

arcto Source #

Arguments

:: Angle

Extent of arc

-> Point

Center of arc

-> Draw () 

Approximate a circular arc by one cubic bezier curve. larger arc angles mean larger distortions

beginPath :: Point -> Draw () Source #

Begin a new path at a position

closePath :: Draw () Source #

Close current path

addBezierCubic :: Point -> Point -> Point -> Draw () Source #

Append a cubic Bezier curve to the current path. The curve extends from the current point to the point (x3 , y3), using (x1 , y1 ) and (x2, y2) as the Bezier control points

addPolygonToPath :: [Point] -> Draw () Source #

Add a polygon to current path

strokePath :: Draw () Source #

Draw current path

fillPath :: Draw () Source #

Fill current path

fillAndStrokePath :: Draw () Source #

Fill current path

fillPathEO :: Draw () Source #

Fill current path using even odd rule

fillAndStrokePathEO :: Draw () Source #

Fill current path using even odd rule

setAsClipPath :: Draw () Source #

Set clipping path

setAsClipPathEO :: Draw () Source #

Set clipping path
