struct mrpt::img::TColorManager

Overview

Manage R, G, B color triads and ask class instance of the next unique RGB combination.

#include <mrpt/img/TColorManager.h>

{
    // fields

    mrpt::img::TColor curr_color;

};

Fields

bool use_standard_colors_first

Indicates if the standard colors are to be returned first.

bool have_used_standard_colors = false

Indicates if the standard colors have already been used.

This is a cached version of the value returned from the checkStdColorsUsed method.

Standard colors are: red, green, blue

Construction

TColorManager(bool use_standard_colors_first = true)

Constructor.

Methods

mrpt::img::TColorf getNextTColorf()

Get the next RGB triad in TColorf form.

Method automatically advances the current counters for RGB.

mrpt::img::TColor getNextTColor()

Get the next RGB triad in TColor form.

Method automatically advances the current counters for RGB.

bool checkStdColorsUsed()

Check if the standard colors have already been used.

ret True if they have indeed been used.
