Detailed Description

Abstract interface for drawing on a 2D-surface.

The functions are optimized for drawing shapes of an EDA-program such as KiCad. Most methods are abstract and need to be implemented by a lower layer, for example by a Cairo or OpenGL implementation. Almost all methods use world coordinates as arguments. The board design is defined in world space units for drawing purposes these are transformed to screen units with this layer. So zooming is handled here as well.

Member Function Documentation

◆ AdvanceDepth()

void KIGFX::GAL::AdvanceDepth ( )

inline

Change the current depth to deeper, so it is possible to draw objects right beneath other.

  {
  m_layerDepth -= 0.05;

◆ BeginDrawing()

virtual void KIGFX::GAL::BeginDrawing ( )

inlinevirtual

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.

◆ DrawArc()

virtual void KIGFX::GAL::DrawArc	(	const VECTOR2D &	aCenterPoint,

		double	aRadius,
		double	aStartAngle,
		double	aEndAngle,
		double	aWidth,
		double	aMaxError
	)

inlinevirtual

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

aCenterPoint	is the center point of the arc.
aRadius	is the arc radius.
aStartAngle	is the start angle of the arc.
aEndAngle	is the end angle of the arc.
aWidth	is the thickness of the arc (pen size).
aMaxError	is 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.

◆ SetNegativeDrawMode()

virtual void KIGFX::GAL::SetNegativeDrawMode ( bool aSetting )

inlinevirtual

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

aSetting is true if negative mode should be enabled
