◆ BeginDrawing()

void CAIRO_GAL_BASE::BeginDrawing ( )
overridevirtual

Start/end drawing functions, draw calls can be only made in between the calls to BeginDrawing()/EndDrawing().

Normally you should create a GAL_DRAWING_CONTEXT RAII object, but I'm leaving these functions public for more precise (i.e. timing/profiling) control of the drawing process - Tom Begin the drawing, needs to be called for every new frame. Use GAL_DRAWING_CONTEXT RAII object unless you know what you're doing.

◆ DrawArcSegment()

void CAIRO_GAL_BASE::DrawArcSegment ( const VECTOR2D aCenterPoint,
double  aRadius,
const EDA_ANGLE aStartAngle,
const EDA_ANGLE aAngle,
double  aWidth,
double  aMaxError 
)
overridevirtual

Draw an arc segment.

This method differs from DrawArc() in what happens when fill/stroke are on or off. DrawArc() draws a "pie piece" when fill is turned on, and a thick stroke when fill is off. DrawArcSegment() with fill on behaves like DrawArc() with fill off. DrawArcSegment() with fill off draws the outline of what it would have drawn with fill on.

TODO: Unify Arc routines

Parameters
aCenterPointis the center point of the arc.
aRadiusis the arc radius.
aStartAngleis the start angle of the arc.
aAngleis the angle of the arc.
aWidthis the thickness of the arc (pen size).
aMaxErroris the max allowed error to create segments to approximate a circle. It has meaning only for back ends that can't draw a true arc, and use segments to approximate. Note: aMaxError is not used in Cairo, because Cairo can draw true arcs

◆ SetNegativeDrawMode()

void CAIRO_GAL_BASE::SetNegativeDrawMode ( bool  aSetting)
overridevirtual

Set negative draw mode in the renderer.

When negative mode is enabled, drawn items will subtract from previously drawn items. This is mainly needed for Gerber negative item support in Cairo, since unlike in OpenGL, objects drawn with zero opacity on top of other objects would not normally mask objects in Cairo. This method is a no-op in OpenGL.

Parameters
aSettingis true if negative mode should be enabled
