我是Clojure的新手,我想在屏幕上画一条线和圆圈,它应该是抗锯齿,怎么办呢?如果有人可以粘贴一些示例代码给我?
另一个问题,我定义了一个地图:
(def {:a 1, :b 2, :c 3}, i try to change it to be {:a 1, :b 99, :c 3},
怎么做?
答案 0 :(得分:1)
看看Quil。 https://github.com/quil/quil
它基于处理http://processing.org,很容易上班。
我认为这可以做你想要的......改编自例子:
(ns foo
(:use quil.core))
(defn setup []
(smooth) ;;Turn on anti-aliasing
(frame-rate 10) ;;Set framerate to 10 FPS
(background 200)) ;;Set the background colour to
;; a nice shade of grey.
(defn draw []
(stroke 0) ;;Set the stroke colour to a black
(stroke-weight 3) ;;Set the stroke thickness to 3
(line 10 10 50 50)
(line 20 20 100 50))
(defsketch example ;;Define a new sketch named example
:title "foo" ;;Set the title of the sketch
:setup setup ;;Specify the setup fn
:draw draw ;;Specify the draw fn
:size [323 200])
