title: Plot multiple coordinates on white images on Matlab or Python
body: <p>I have multiple .txt files like this</p>
  
  <pre><code>Detected 4
  block 0: sig: 1 x: 112 y: 96 
  block 1: sig: 1 x: 15 y: 110
  block 2: sig: 1 x: 112 y: 131 
  block 3: sig: 1 x: 252 y: 80

  <p>I want to import the x,y coordinates and plot them on a white 240*300 jpeg image that I don't have.( This means I have to create the white image ) I have more than 1000 txt files and want to make the plotted images for each txt file.
  It would be great if I could change the size of the plots easily.</p>
  
  <p>Add</p>
  
  <p>These multiple txt files come form an original txt file like this.</p>

  <p>I just split it so that it makes it easier to reference them later but I still have this original file.</p>
