Hello!
A sprite made in Photoshop with, for example, 10x10px was used in my project. At 100% scale I thought it was at its original size and every square there was a pixel. But by decreasing this sprite to 1% scale there was no distortion, all the painted pixels were there, raising the question: what is the displayed size, because a pixel could not be even smaller.
The same happened with a degraded circle (made in larger proportions). By lowering it to a size smaller than the 10x10 pixel art for example, it continued a great, non-pixelated circle and with a great gradient. this at the minimum scale size of the Construct properties window, and smaller thant my 10x10 pixel art, what give me the impression that a lot of pixels ( necessary to make a circle and a degrade) is fiting in a one pixel space.
So I'm not understanding the size parameters and how its really works in the layout.
