Question

好的，最近我一直在试验朱莉娅的compose.jl，并遇到了一个有点令人困惑的问题。我将运行标准代码来初始化包。

Pkg.add("Compose")
using Compose
compose(compose(context(), rectangle()), fill("tomato"))

然后运行该代码。这是我的问题：代码执行正常，输出很奇怪。此代码的典型输出是红色矩形。运行此代码时得到的输出是：

Context(BoundingBox(Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,0.0),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,0.0),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),1.0,0.0),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,1.0)),UnitBox{Nothing,Nothing,Nothing,Nothing}(nothing,nothing,nothing,nothing,Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,0.0),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,0.0),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,0.0),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,0.0)),Rotation{Point{Measure{MeasureNil,MeasureNil},Measure{MeasureNil,MeasureNil}}}(0.0,Point{Measure{MeasureNil,MeasureNil},Measure{MeasureNil,MeasureNil}}(Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.5,0.0),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,0.5))),nothing,ListNode{ComposeNode}(Property{FillPrimitive}([FillPrimitive(AlphaColorValue{RGB{Float64},Float64}(RGB{Float64}(1.0,0.38823529411764707,0.2784313725490196),1.0))]),ListNode{ComposeNode}(Form{RectanglePrimitive{P<:Point{XM<:Measure{S,T},YM<:Measure{S,T}},M1<:Measure{S,T},M2<:Measure{S,T}}}(RectanglePrimitive[RectanglePrimitive{Point{Measure{MeasureNil,MeasureNil},Measure{MeasureNil,MeasureNil}},Measure{MeasureNil,MeasureNil},Measure{MeasureNil,MeasureNil}}(Point{Measure{MeasureNil,MeasureNil},Measure{MeasureNil,MeasureNil}}(Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,0.0),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,0.0)),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),1.0,0.0),Measure{MeasureNil,MeasureNil}(0.0,MeasureNil(),MeasureNil(),0.0,1.0))]),ListNull{ComposeNode}())),0,false,false,false,false,nothing,nothing,0.0)

一段相当冗长的文字，没有显示形状...我想知道这是一个错误还是我只是做错了什么。有谁知道如何使这个输出应该是什么？

通过REPL打开图像的一种可能性是通过TerminalExtensions.jl。但通常我认为你必须将图像写入文件然后打开它。要保存文件，请使用

julia>draw(PNG("test.png", 10inch, 10inch), compose(compose(context(), rectangle()), fill("tomato")))

Compose.jl输出问题
