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.

If you do this, you should consider using a GAL_SCOPED_ATTR to ensure the depth is reset to the original value.

Definition at line 439 of file graphics_abstraction_layer.h.

References m_layerDepth, and SetLayerDepth().

◆ 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.

		double	aRadius,
		const EDA_ANGLE &	aStartAngle,
		const EDA_ANGLE &	aAngle,
		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.

This has meaning only for back ends that can't draw a true arc, and use segments to approximate.

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.
aAngle	is the 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.
