title: Matplotlib Plots Lose Transparency When Saving as .ps/.eps
body: <p>I'm having an issue with attempting to save some plots with transparent ellipsoids on them if I attempt to save them with .ps/.eps extensions. </p>
  
  <p>Here's the plot saved as a .png:
  <img src="https://i.stack.imgur.com/w55jg.png" alt="png"></p>
  
  <p>If I choose to save it as a .ps/.eps here is what it looks like:
  <img src="https://i.stack.imgur.com/loXbC.png" alt="ps"></p>
  
  <p>How I got around this, was to use ImageMagick to convert the original png to a ps. The only problem is that the image in png format is about 90k, and it becomes just under 4M after conversion. This is not good since I have a lot of these images, and it will take too much time to compile my latex document. Does anyone have a solution to this?</p>
