Irfanview: how to zoom-in without having the image blurred

Question

I have a added my app in Chartboost for my iOS app. But by mistake a have created two apps. Now I am unable to find out a way to delete it. Please tell me is there any way to delete it?

Solution

I found the solution by reading changelog

New display option: Use Resample for zooming (Menu: View->Display options)

So from "View" menu, select "Display options" and turn off "Use resample".

What type of files are they, and does if Infranview can't do it, does it have to be that program?

I'm talking about screenshots (taken with [Alt+]Print, then pasted), not about viewing files.

I had to adjust zoom for the setting to kick in.

Thanks--I've been wondering why suddenly Irfanview was no longer giving me a precise zoomed view of my images!

Thanks! baffling to me that there are a separate set of options which are not under the Options menu.
