title: Ghostscript embedded fonts and substitution
body: <p>I'm converting PDF to JPG with gs.</p>
  
  <p>Does gs substitute embedded fonts? How exactly this works? Like if i embed all fonts that is used in PDF does gs still look for some substitution or can it use that embedded font data?</p>
  
  <p>So does embedding fonts in PDF mean that all glyphs used in PDF with that font is being embedded and i don't need to have that font in my gs font path?</p>
  
  <p>Thanks!</p>
