FT_Outline_New

ft_Outline_New Source #

Arguments

:: FT_Library	library
-> FT_UInt	numPoints
-> FT_Int	numContours
-> IO (Ptr FT_Outline)	outline

Newly created FT_Outline is allocated using malloc and thus must be freed manually.

ft_Outline_With Source #

Arguments

:: FT_Library	library
-> FT_UInt	numPoints
-> FT_Int	numContours
-> (Ptr FT_Outline -> IO a)
-> IO a

bracket over ft_Outline_New and ft_Outline_Done.

The provided Ptr FT_Outline should not be used after this function terminates.

FT_Outline_Done

ft_Outline_Done Source #

Arguments

:: FT_Library	library
-> Ptr FT_Outline	outline
-> IO ()

Additionally frees the passed pointer.

FT_Outline_Copy

Arguments

:: Ptr FT_Outline	outline
-> FT_Matrix	matrix
-> IO ()

FT_Outline_Embolden

ft_Outline_Embolden Source #

Arguments

:: Ptr FT_Outline	outline
-> FT_Pos	strength
-> IO ()

FT_Outline_EmboldenXY

ft_Outline_EmboldenXY Source #

Arguments

:: Ptr FT_Outline	outline
-> FT_Pos	xstrength
-> FT_Pos	ystrength
-> IO ()

FT_Outline_Reverse

ft_Outline_Reverse Source #

Arguments

:: Ptr FT_Outline	outline
-> IO ()

FT_Outline_Check

ft_Outline_Check Source #

Arguments

:: Ptr FT_Outline	outline
-> IO ()

FT_Outline_Get_CBox

ft_Outline_Get_CBox Source #

Arguments

:: Ptr FT_Outline	outline
-> IO FT_BBox	cbox

FT_Outline_Get_BBox

ft_Outline_Get_BBox Source #

Arguments

:: Ptr FT_Outline	outline
-> IO FT_BBox	bbox

FT_Outline_Get_Bitmap

ft_Outline_Get_Bitmap Source #

Arguments

:: FT_Library	library
-> Ptr FT_Outline	outline
-> Ptr FT_Bitmap	bitmap
-> IO ()

FT_Outline_Render

ft_Outline_Render Source #

Arguments

:: FT_Library	library
-> Ptr FT_Outline	outline
-> Ptr FT_Raster_Params	params
-> IO ()

FT_Outline_Decompose

ft_Outline_Decompose Source #

Arguments

:: Ptr FT_Outline	outline
-> FT_Outline_Funcs	func_interface
-> Ptr ()	user
-> IO ()

FT_Outline_Funcs is only used as an argument (and this is the only function using it), so it's silently converted to FT_Outline_Funcs' inside.
