PFA - pdf i used to extract images, screenshots of the error.
The code i used is the one mentioned in the documentation.
It is not converting imagetype : x-wmf to jpeg and is failing to save it.
PDF:
pptexamples.zip …...jpeg, "emf": draw.imaging.ImageFormat.emf, "bmp": draw...return { "jpeg": "jpg", "emf": "emf", "bmp": "bmp", "png": "png"...
