When mouse is dragged through a ruler to create a new guide, I want this guide to move pixel by pixel so that when I leave it, it will have snapped to a side of a pixel instead of staying in the middle.
How can I achieve this?
You need to be at 500% zoom or higher and then hold Shift+Mouse Button to have your guides snap to the pixel grid.
Otherwise, by default it'll snap to:
However, if you set your grid to every pixel, then it should snap to the pixel at 100% zoom or greater, even if
But I usually just use the rectangular marquee to mark out the positions where I want my guides to snap to. This avoids having to zoom in or having to change my grid settings.
Also when you select View > New Guide and specify a vertical position does this snap correctly?
Sorry if this is duplicating previous suggestions.
