USER_POINT scale_P1P2

(

)

Something else that should not be used.

void translate_init

(

)

Initialize translation and scale.

Translation is not implemented.

void translate_scale

(

)

Use IP and SC data to calculate the scale and translation.

Translation is not implemented.

void userprescale	(	double	absx,
		double	absy,
		double *	ox,
		double *	oy
	)

Something that shouldn't be used.

void userscale	(	double	fx,
		double	fy,
		int16_t *	x,
		int16_t *	y,
		double *	ox,
		double *	oy
	)

Transform user coordinates (fx,fy) into plotter coordinates (x,y) according to the transform defined by IP/SC. Then do reverse transform, round and assign resulting values to (ox,oy).

Parameters:

	fx	user coordinates x
	fy	user coordinates y
	*x	(output) absolute stepper x
	*y	(output) absolute stepper y
	*ox	(output) corrected fx
	*oy	(output) corrected fy
