Images in PDF blurred at 100% zoom?


When viewing PDFs at 100% zoom, images still seem blurred.
In another viewer they look sharp, same as the original image files.
Is there a setting to control this resampling behavior?


I would need access to PDF and screenshots of blurred vs. non-blurred version.


Thanks. After what you said I checked it more carefully.
It doesn’t happen in all cases. Maybe it depends on the resolution of the images.

Here’s a sample:

Original PNG.
The PDF.
