Struct fltk::surface::ImageSurface

pub struct ImageSurface { /* fields omitted */ }

An image surface object. Example usage:

use fltk::{prelude::*, *};
let but = button::Button::new(0, 0, 80, 40, "Click");
let sur = surface::ImageSurface::new(but.width(), but.height(), false);
surface::ImageSurface::push_current(&sur);
draw::set_draw_color(enums::Color::White);
draw::draw_rectf(0, 0, but.width(), but.height());
sur.draw(&but, 0, 0);
let img = sur.image().unwrap();
surface::ImageSurface::pop_current();
