ra8_touch_cal_point_t Struct Reference

One (x, y) integer coordinate pair. More...

#include <ra8_touch_cal.h>

Data Fields
int32_t	x
	Horizontal coordinate.
int32_t	y
	Vertical coordinate.

Detailed Description

One (x, y) integer coordinate pair.

Used both for screen-space target locations (passed to draw_target_fn) and for the raw controller-space samples returned by read_raw_fn. Components are int32_t so transforms that temporarily produce negative intermediate values do not wrap. Final mapped pixel coordinates are still clipped into the panel rectangle by ra8_touch_cal_apply.

Invariant

Components fit a 16-bit panel; the wider type is for arithmetic head-room only.
