drawLine()

template<class arrayT >

void mx::wfp::drawLine	(	arrayT &	im,
		typename arrayT::Scalar	x0,
		typename arrayT::Scalar	y0,
		typename arrayT::Scalar	x1,
		typename arrayT::Scalar	y1,
		typename arrayT::Scalar	halfWidth
	)

Draw a line in an image.

Todo:

should handle width much more intelligently, this only works for ~45 degree lines.

Template Parameters

arrayT

is an Eigen-like array with public typedef Scalar

Parameters

	im	[in.out] The input image, modified.
[in]	x0	the x value, relative to image center, of the starting point
[in]	y0	the y value, relative to image center, of the starting point
[in]	x1	the x value, relative to image center, of the end point
[in]	y1	the y value, relative to image center, of the end point
[in]	halfWidth	the half-width of the line.
