> I tried to create a image and superimpose on the PDF, the image looks fuzzy.
> Also if i try to zoom the image created it looks fuzzy even for the first
> Zoom Out.
> I tried increasing the resolution this is increasing the image size while
> superimposing and even looks more fuzzy with a huge image. Tried with the
> below piece of code.
