PerspectiveIteratorX

agg_rust::trans_perspective

Struct PerspectiveIteratorX 

Source 
pub struct PerspectiveIteratorX {
    pub x: f64,
    pub y: f64,
    /* private fields */
}
Expand description

Incremental iterator for scanline walking with perspective transform.

Maintains running numerator/denominator for perspective divide without full division at each pixel (only one divide per step).

Port of C++ trans_perspective::iterator_x.

Fields§

§x: f64§y: f64
