Classes
struct	TICK_FORMAT
	Description of a "tick format" for a scale factor - how many ticks there are between medium/major ticks and how each scale relates to the last one. More...

Functions
static int	getShadowLayer (KIGFX::GAL *aGal)

static double	getTickLineWidth (const TEXT_DIMS &textDims, bool aDrawingDropShadows)

static TICK_FORMAT	getTickFormatForScale (double aScale, double &aTickSpace, EDA_UNITS aUnits)

void	drawTicksAlongLine (KIGFX::VIEW *aView, const VECTOR2D &aOrigin, const VECTOR2D &aLine, double aMinorTickLen, const EDA_IU_SCALE &aIuScale, EDA_UNITS aUnits, bool aDrawingDropShadows)
	Draw labeled ticks on a line.

void	drawBacksideTicks (KIGFX::VIEW *aView, const VECTOR2D &aOrigin, const VECTOR2D &aLine, double aTickLen, int aNumDivisions, bool aDrawingDropShadows)
	Draw simple ticks on the back of a line such that the line is divided into n parts.

Variables
