Function libnotcurses_sys::ncvisual_blitter_geom

pub unsafe extern "C" fn ncvisual_blitter_geom(
    nc: *const notcurses, 
    n: *const ncvisual, 
    vopts: *const ncvisual_options, 
    y: *mut c_int, 
    x: *mut c_int, 
    scaley: *mut c_int, 
    scalex: *mut c_int, 
    blitter: *mut ncblitter_e
) -> c_int

Get the size and ratio of ncvisual pixels to output cells along the y and x axes. The input size (in pixels) will be written to ‘y’ and ‘x’. The scaling will be written to ‘scaley’ and ‘scalex’. With these: rows = (y / scaley) + !!(y % scaley) or (y + scaley - 1) / scaley cols = (x / scalex) + !!(x % scalex) or (x + scalex - 1) / scalex Returns non-zero for an invalid ‘vopts’. The blitter that will be used is returned in ‘*blitter’.
