Detailed Description

Class GAL is the 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.

virtual void KIGFX::GAL::DrawArcSegment ( const VECTOR2D aCenterPoint,
double  aRadius,

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.

Parameters
aCenterPointis the center point of the arc.
aRadiusis the arc radius.
aStartAngleis the start angle of the arc.
aEndAngleis the end angle of the arc.
aWidthis the thickness of the arc (pen size).

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

Sets 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
