100% zoom not working as expected


Recommended Posts

I have encountered a problem with zooming using Ctrl+mousewheel. When I zoom e.g. from 89% to 100% (as shown in toolbar), the image itself is stretched a little - some pixels looks fuzzy and this represantation is unusable for direct pixel manipulation because the user can not rely on what he sees.

I think the problem is caused by some internally keeped zoom value (e.g. 100.0023%) but as a user I want to be sure that for 100% and multiplicities I can see the whole pixel. Otherwise I cannot use Paint.NET for pixel manipulation which is pity.

See this screenshot:


Thanks for the answer if this is considered as a bug and will be fixed in new versions.

Confirmed. When scrolling with Ctrl+Mousewheel, the zoom level is not 100% when it displays 100%.

Repro steps:

1. Create an image with clearly defined (i.e. non-anti-aliased) lines.

2. Go to a zoom level of 89%.

3. Zoom in one click with the Ctrl+Mousewheel method.

4. Note the anti-aliasing.


The Doctor: There was a goblin, or a trickster, or a warrior... A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.
Amy: But how did it end up in there?
The Doctor: You know fairy tales. A good wizard tricked it.
River Song: I hate good wizards in fairy tales; they always turn out to be him.
