void APERTURE_MACRO::DrawApertureMacroShape	(	GERBER_DRAW_ITEM *	aParent,
		EDA_RECT *	aClipBox,
		wxDC *	aDC,
		COLOR4D	aColor,
		wxPoint	aShapePos,
		bool	aFilledShape
	)

Function DrawApertureMacroShape Draw the primitive shape for flashed items.

When an item is flashed, this is the shape of the item

Parameters

aParent	= the parent GERBER_DRAW_ITEM which is actually drawn
aClipBox	= DC clip box (NULL is no clip)
aDC	= device context
aColor	= the color of shape
aShapePos	= the actual shape position
aFilledShape	= true to draw in filled mode, false to draw in skecth mode

double APERTURE_MACRO::GetLocalParam	(	const D_CODE *	aDcode,

	)		const

function GetLocalParam Usually, parameters are defined inside the aperture primitive using immediate mode or defered mode.

in defered mode the value is defined in a DCODE that want to use the aperture macro. But some parameters are defined outside the aperture primitive and are local to the aperture macro

Returns: the value of a defered parameter defined inside the aperture macro

Parameters

aDcode	= the D_CODE that uses this apertur macro and define defered parameters
aParamId	= the param id (defined by $3 or $5 ..) to evaluate

in defered mode the value is defined in a DCODE that want to use the aperture macro. But some parameters are defined outside the aperture primitive and are local to the aperture macro

Returns: the value of a defered parameter defined inside the aperture macro

Parameters

aParamId = the param id (defined by $3 or $5 ..) to evaluate
