Types

type Point = (PDFFloat, PDFFloat)

A point

Lines

moveto

:: PDFFloat Horizontal coordinate -> PDFFloat Vertical coordinate -> Draw () Move pen to a given point without drawing anything

lineto

:: PDFFloat Horizontal coordinate -> PDFFloat Vertical coordinate -> Draw () Draw a line from current point to the one specified by lineto

Paths

beginPath

:: PDFFloat Horizontal coordinate -> PDFFloat Vertical coordinate -> Draw () Begin a new path at position x y

closePath :: Draw ()

Close current path

addBezierCubic

:: PDFFloat x1 -> PDFFloat y1 -> PDFFloat x2 -> PDFFloat y2 -> PDFFloat x3 -> PDFFloat y3 -> Draw () 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 ()

Add a polygon to current path

addLineToPath

:: PDFFloat Horizontal coordinate -> PDFFloat Vertical coordinate -> Draw () Add a line from current point to the one specified by lineto

strokePath :: Draw ()

Draw current path

fillPath :: Draw ()

Fill current path

fillAndStrokePath :: Draw ()

Fill current path

fillPathEO :: Draw ()

Fill current path using even odd rule

fillAndStrokePathEO :: Draw ()

Fill current path using even odd rule

setAsClipPath :: Draw ()

Set clipping path

setAsClipPathEO :: Draw ()

Set clipping path
