◆ SpikeDesc()

anonymous_namespace{Emboss.cpp}::SpikeDesc::SpikeDesc	(	double	bevel_size,
		double	pixel_spike_length = 6 )

inline

Calculate spike description.

Parameters

bevel_size	Size of spike width after cut of the tip, has to be grater than 2.5
pixel_spike_length	When spike has same or more pixels with width less than 1 pixel

                                                               :         
        // create min angle given by spike_length
        // Use it as minimal height of 1 pixel base spike
        cos_angle(std::fabs(std::cos(
            /*angle*/ 2. * std::atan2(pixel_spike_length, .5)
        ))),
 
        // When remove spike this angle is set.
        // Value must be grater than min_angle
        half_bevel(bevel_size / 2)
