Polygonal Lasso snapping to pixels when snapping is off

[imfastrnu2 4]

I cannot figure out how to COMPLETELY turn snapping of for the Polygonal Lasso tool. It's difficult to describe so I've included images. Basically, if I turn all snapping off in Photoshop I can Lasso select between pixels which is truly free selecting. When I try this in Affinity Photo it  snaps by pixel, there is no "between the pixels". Please refer to the images to see what I'm trying to say.

I need Affinity to stop snapping to pixels and let me select the way Photoshop does.

I assume this is Adobe Photoshop compared to Affinity Photo?

How does the actual selection look in comparison, I suspect Adobe will have to make a choice between the left side or right side of the polygon line. I'll check in Adobe.

An alternative way is to use the pen tool to make the shape you want and then convert it to a selection, this requires that the shape has a fill first.

As I thought, Adobe picks the closest pixel edge.

There is an element of ambiguity in how adobes non-snapping selection works, so you have to be aware of where the selection is made, doing the same thing in Affinity Photo removes that ambiguity and lets you make the selection you want because it's only going to be the pixel edge to the left or the pixel edge to the right.

Ahh...I see exactly what your saying now. I think what's happening is the "feel" of selecting for me. In Adobe I can move about freely between pixels why selecting but when I catually close the selection loop it does indeed jump to the nearest pixel edge. I simply wasn't noticing that because I'm generally not zoomed in that far when I close the selection. Affinity's lasso just jumps to the nearest pixel edge no matter what. I'm fine with that, now that I know exactly what's happening.

 

Thank you!
