> 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.
