Function Documentation

CPU_CHAR search_contrast	(	CPU_CHAR	tolerance,
		t_img *	img_in1,
		t_img *	img_out,
		CPU_INT32U	RGB,
		CPU_INT32U	color,
		CPU_CHAR	direction
	)

Search constrast between two adjacent pixel.

Parameters

tolerance	CPU_CHAR - tolerance in % between two pixel
img_in1	t_img* - input image
img_out	t_img* - output image
RGB	CPU_INT32U - replacement color for detected pixel
color	CPU_INT32U - range of color to work on
direction	CPU_CHAR - HOR,VER or DIAG to indicate direction of detection

Returns

CPU_CHAR - status of search

Search constrast between two adjacent pixel on a given direction, according to a color
