Zoom Levels

[Fleabag]

I’ve noticed in the ColorPerfect feature overview YouTube video, the zoom function has 20,25,33.33,50 & 100% where as v3 has 33.33, 50, 100%. Is there a setting to add the additional zoom levels?

The Zoom levels available to you depend on three things:

• Image size in pixels

• Dialog size on screen

• Pixel density of said screen (Retina or not for macOS)

So, try making your plug-in window be the smallest possible and get a different list.
Or for testing resample your image to double its original size and get a different list of zoom levels also.
If you have a Retina display PhotoLine will give a different list (preview not in high DPI mode) or an external screen in PS may do so.
