[By Design] Slices are not pixel perfect

Recommended Posts

Hi, I have an artboard which when selected to create a slice out of, the slice often and unpredictably adds a pixel either to one of the edges, in this case, it adds an extra pixel to the height. Please see the screenshots below

In the transform panel, you can see that the artboard is positioned with whole pixels and has dimensions made up whole pixels. I've even done the 1pixel nudge left and right fix which I heard might fix the problem to ensure 100% whole pixel alignment.

However, you can see the export persona selective slicing has added an extra pixel to the top of the slice. It doesn't always do this but it does it often enough for me to have to check every single side on every single slice to make sure the slices are cropped correctly. 

It's not a big deal for most exports but it is a problem for such things as repeating bg patterns used on website and also for creating texture brushes. For example, if overlooked, you get a pixel thin white streak in the stroke and then you have to go right back to fixing it, importing the brush, adjusting all the settings and reapplying the stroke to all your brush strokes - it's been a bit of a nightmare!

If you would like the file I'm working with, I'd like to send it privately if OK so please advise.

Many thanks.

I suggest opening your Affinity Preferences, Tools  User Interface section, and checking how many decimal places you have specified for px measurements. It needs to be at least 1, and possibly 2, to be sure of the positioning.

We're having the same issue here at work! It's pretty nagging... sadly, I cannot find this decimal places setting in my version of AD.

It's in all the desktop versions of Designer. In the Preferences dialog, under ToolsUser Interface. (Sorry; wrong panel originally.)

Here's a screenshot of my pref panel... the bottom four settings translate as: 

- Tool "move" scale

- Create text with mixed gamma

- Nudge increments

- Nudge with modifier keys increments
