title: I don't want to create a PDF, if I don't want to use a pdf already saved on my desktop, is it possible using Canvas?
body: <p>I found this code on the web, but I would like to be able to load a template and not create a PDF:</p>
  <pre><code>canvas = canvas.Canvas(&quot;helloworld.pdf&quot;, pagesize=letter,) #Load template.pdf, not create PDF
  
  canvas.setFont('Helvetica', 25)
  
  canvas.drawString(20 * mm, 100 * mm , &quot;Esto es un texto&quot;)
  logo = ImageReader(f&quot;{mainpath}/abc.png&quot;)
  canvas.drawImage(logo, 10*mm, 240*mm , width=  100*mm ,  height= 50*mm,  preserveAspectRatio=True)  
  canvas.save()
  mostrar_pdf(&quot;helloworld.pdf&quot;)
  </code></pre>
