Question

所以，我是编程的新手，我现在正在使用带有Tkinter和Canvas的rapsberry pi 3上的Python创建一个交互式地图，供学生对他们在校园周围看到的动物进行编目。我遇到的问题是找到一种方法来创建一个图像，该图像是各个地图上每个人的输入的组合，以显示在这个新地图上。我最终会做的是将这个代码嵌入wordpress php（我已经找到了一个代码）。

我想到的一个可能的事情是将图像保存为postscript文档，然后将该文档用于Image Magick之类的东西，并以某种方式将图像覆盖在彼此的顶部，尽管我不确定它会如何＆＃ 34;更新＆＃34;

如果有人对python 2.9.7

感兴趣，这是我的交互式地图代码

import base64
import Tkinter
import urllib

def getaddress (location, width, height, zoom):
    locationnospaces = urllib.quote_plus(location)
    address = "http://maps.googleapis.com/maps/api/staticmap?\
center={0}&zoom={1}&size={2}x{3}&format=gif&sensor=false"\
.format(locationnospaces, zoom, width, height)
    return address

def getmap (location, width, height, zoom):
    address = getaddress(location, width, height, zoom)
    urlreader = urllib.urlopen(address)
    data = urlreader.read()
    urlreader.close()
    base64data = base64.encodestring(data)
    image = Tkinter.PhotoImage(data=base64data)
    return image

def getlabelname():
    popup = Tkinter.Toplevel()
    popup.title("Rabbit Season")
    label = Tkinter.Label(popup, text="Date/Time of Sighting")
    label.pack()

    labelname = Tkinter.StringVar()
    textbox = Tkinter.Entry(popup, textvariable=labelname)
    textbox.pack()
    textbox.focus_force()

    button = Tkinter.Button(popup, text ="Done", command=popup.destroy)
    button.pack()

    popup.wait_window()

    text = labelname.get()
    return text

def canvasclick(event):
    x,y = event.x, event.y
    widget = event.widget
    size = 10
    widget.create_oval(x-size, y-size, x+size, y+size, width=2)
    label = getlabelname()
    widget.create_text(x, y+2*size, text=label)


location = "Adelphi University"
width = 640
height = 480
zoom = 16

window = Tkinter.Tk()
window.title(location)
window.minsize(width, height)
window.maxsize(width, height)

mapimage = getmap(location, width, height, zoom)
canvas = Tkinter.Canvas(window, width=width, height=height)
canvas.create_image(0,0,image=mapimage,anchor=Tkinter.NW)
canvas.bind("<Button-1>",canvasclick)
canvas.pack()
window.mainloop()
