ColorRange¶

Type:	Matrix<float>
Range:	[v_11, …, v_1j; …; v_i1, …; v_ij], i<=3, j<=2
Default:	-/-
Appearance:	simple
Excludes:	GrayRange

Color range as a rgb (red-green-blue) box (3x2 matrix).

A rgb color $[r,g,b]$ is normalized so that $0.0\leq r,g,b \leq 1.0$ . The color range box is defined as

$\begin{eqnarray*} \left[ \begin{array}{cc } r_\mathrm{min} & r_\mathrm{max} \\ g_\mathrm{min} & g_\mathrm{max} \\ b_\mathrm{min} & b_\mathrm{max} \\ \end{array} \right] \end{eqnarray*}$

A pixel with with color $[r,g,b]$ is selected if

$\begin{eqnarray*} r_\mathrm{min} & \leq & r \leq r_\mathrm{max} \\ g_\mathrm{min} & \leq & g \leq g_\mathrm{max} \\ b_\mathrm{min} & \leq & b \leq b_\mathrm{max} \end{eqnarray*}$
