shapes

I have a set of coordinates that I turn into an svg path (using cubic beziers to make it smooth). When I apply a certain stroke width, I get the following result (the blue dots are my coordinates) What I am interested in is to get a path that runs around the gray shape (like: pick any point on the gray/white border, and round around the shape until you're back at the starting point). How would I go about computing such a path? for reference, this is my svg info: <g> <title>number 3</title> <path d="m238,50c5.67569,-1.01351 11.8327,-3.8229 20.92029,-2.14724c8.68106,0.69732 14.21173,4.90255 18

I've read a bunch of tutorials involving XNA (and it's various versions) and I still am a little confused on drawing primitives. Everything seems to be really convoluted. Can someone show me, using code, the simplest XNA implementation of drawing one or two lines on to the screen? Perhaps with a brief explanation (including the boilerplate)? I'm not a games programmer and I have little XNA experience. My ultimate goal is to draw some lines onto the screen which I will eventually transform with rotations, etc (by hand). However, for this first step.. I need to simply draw the lines! I remember

I'm working on a project in which I use OpenCV to detect shapes and their colors. There are 5 colors (red, green, yellow, blue and white) and 4 shapes (rectangle, star, circle and heart). I've been able to reliably discern the colors and I can detect the shapes when the image used is a drawn image like this using this code. Note, the image is for demonstration only, the range values in my code are not for these colors. import cv2 import numpy as np class Shape(): def __init__(self, color, shape, x, y, approx): self.color = color self.shape = shape self.x = x self.y = y self.approx = approx def

IS it possible, I know all the following shapes are possible in this link: http://css-tricks.com/examples/ShapesOfCSS/ but cross must be possible too. When I say cross I mean like this: You could achieve something like this with pseudoelements only: http://jsbin.com/upiyoc/1/edit #cross { width: 100px; height: 100px; position: relative; } #cross:before, #cross:after { content: ""; position: absolute; z-index: -1; background: #d00; } #cross:before { left: 50%; width: 30%; margin-left: -15%; height: 100%; } #cross:after { top: 50%; height: 30%; margin-top: -15%; width: 100%; } The size of the

I know that if I use randn , import pandas as pd import numpy as np df = pd.DataFrame(np.random.randn(100, 4), columns=list('ABCD')) gives me what I am looking for, but with elements from a normal distribution. But what if I just wanted random integers? randint works by providing a range, but not an array like randn does. So how do I do this with random integers between some range? Anand S Kumar numpy.random.randint accepts a third argument ( size ) , in which you can specify the size of the output array. You can use this to create your DataFrame - df = pd.DataFrame(np.random.randint(0,100
