User:Laurier Rochon/prototyping/flag generator

So you instantiate this class, and it creates an SVG flag! (assuming the dir you are in is writable...)

from vars import *
import random

class Flag:

	def __init__(self):
		self.canvasx=20
		self.canvasy=20
		self.stripes=3
		self.orientation=random.randint(0,1)
		if(self.orientation):
			self.flag_height = 250
			self.twidth=390
			self.theight=round(self.flag_height/self.stripes)
		else:
			self.flag_width = 350
			self.twidth=round(self.flag_width/self.stripes)
			self.theight=200

	def makestripe(self,no):
		hexcode = random.randint(0, 16777215)
		style = "fill:#%x;fill-rule:evenodd;stroke:none" % hexcode
		shapeid = hexcode
		if(self.orientation):
			myx = self.canvasx
			myy = no*(self.theight+1)+self.canvasy			
		else:
			myy = self.canvasy
			myx = no*(self.twidth+1)+self.canvasx

		stripecode = "<rect style='%s' id='%s' width='%s' height='%s' x='%s' y='%s' />" % (style,hexcode,self.twidth,self.theight,myx,myy)
		return stripecode
	
	def makeflag(self,stripes):
		rects_code = ""
		for a in range(0,stripes):
			rects_code = rects_code + self.makestripe(a) + '\n'
		return rects_code;

	def assemble(self):
		all = start + self.makeflag(self.stripes) + end
		return all
	
	def write_svg(self):
		f = open('flag.svg', 'w')
		f.write(self.assemble().strip(' \t\n\r'))
		f.close()

x = Flag()
x.write_svg()

And the imported file. Needed for import to work.
