calcDeltaBasePoint()

std::vector< Geom::Point > Inkscape::UI::Tools::MeasureTool::calcDeltaBasePoint	(	double	dX,
		double	dY
	)

Calculates the base point from which to draw the dX and dY lines.

It puts the point on the opposite side from where the angle is drawn The returned array contains the following points:

___point0 is the base point; ___point1 is the dX normal; ___point2 is the dY normal;
___point3 is the dXbase (mid point along the dX line);
___point4 is the dYbase (mid point along the dY line)

copyToClipboard()

void Inkscape::UI::Tools::MeasureTool::copyToClipboard

(

)

Copies some measurements to the clipboard.

It deals with Alt + C event

It copies the measurements to the clipboard. The settings for what should be copied are in the MeasureToolSettingsDialog. The path to the settings of the MeasureToolSettingsDialog is saved in the preferences, so if for any reason the path of the MeasureToolSettingsDialog is changed, no change is needed here. Probably all settings can go in /tools/measure/, but the other dialogs have their own path starting with /dialog/, so I have done it the same.

The measurements are unset only when they are not visible, visible measurements are always accurate. Measurements that are not visible have not been (re)calculated, so the stored value may be inaccurate.

		Geom::Point const &	end,
		Geom::Point const &	anchor,
		double	angle,
		bool	to_phantom,
		Inkscape::XML::Node *	measure_repr = nullptr

Given an angle, the arc center and edge point, draw an arc segment centered around that edge point.

Parameters

desktop	the desktop that is being used.
center	the center point for the arc.
end	the point that ends at the edge of the arc segment.
anchor	the anchor point for displaying the text label.
angle	the angle of the arc segment to draw.
measure_rpr	the container of the curve if converted to items.

bool Inkscape::UI::Tools::MeasureTool::equalWithinRange	(	double	value,
		double	reference_value,
		double	epsilon,
		bool	positiveAllowed = true,
		bool	negativeAllowed = true
	)

Checks if a value is very close to a reference value and can be considered equal to it.

Parameters

epsilon	the value of the acceptable discrepancy from true equality
positiveAllowed	if true (default) it checks for reference_value + epsilon range
negativeAllowed	if true (default) it checks for reference_value - epsilon range

If value is not allowed to cross a limit, then the range can be limited to either side of the limit by setting the appropriate flag to false
