  Would like to insert pictures to powerpoint.
  How can I set the width and height of the picture?</p>
  
  <p>Code I have now:</p>
  
  <pre><code>from pptx import Presentation 
  from pptx.util import Inches
  
  img_path = 'monty-truth.png'
  
  prs = Presentation() 
  blank_slide_layout = prs.slide_layouts[6] 
  slide = prs.slides.add_slide(blank_slide_layout)
  
  left = top = Inches(1)
  pic = slide.shapes.add_picture(img_path, left, top) 
  prs.save('test.pptx')
  </code></pre>
