Exporting outlined adds unwanted padding

[Xakiru]

This image was supposed to be 128x128, but it got exported to 130x130

Are the pixel values in the Transform Panel actually integers, or do they just look like integers because of rounding?

Try changing the Decimal Places settings to three (or more) via Preferences / User Interface and check again.

Are there any Quick Effects applied to the parent layer(s) of that layer?

When you export that layer, how do you export it? File → Export, or the Export Persona?

Note: Full-screen screenshots are often more useful than small screen-grabs as we get more information at the same time.

Side note: This happens in both V1 and V2.

Here I started a new document of 256x256px

 

I added a black square of 124x124px + outline of 2px (which becomes 4px since it's from both sides), I export to PNG (Ctrl+Alt+Shift) and here is the result. 

Just to make sure, I've just set everything in decimal places to 0 (I have no idea what these do).

 

 

The result png file (opened in affinity):

 

I attached the file, just in case.

Outline leads to partially transparent pixels. The export includes them, even if they are barely visible. 
 

better use stroke to outside.

I think you meant “Ctrl+Alt+Shift+S” to get to the export dialog.
Have you tried using the Export Persona instead?

Setting the Decimal Places settings to zero will not show any decimal places.
If you do as I said earlier, “Try changing the Decimal Places settings to three (or more)” then you should be able to see the decimal places, if there are any.

As NotMyFault said above, in this sort of case you probably should be using a Stroke on the Outside rather than the Outline Quick Effect.

Same result with stroke my friend

Yea I meant clrl+alt+shift+S
I didn't try to use persona export cuz I'm not planning to cut out every single item I'm exporting while they are already in separate layers.
I didn't read well about the "three or more", I changed it to 3, and it somehow worked, what does the decimal places for unit mean ?

This is a old bug unearthed again. Probably a rounding issue. Clip canvas shows the extra pixel, too. 
If you rasterize and trim, no extra pixel. 
 

If you add strokes or outlines, this will add the stroke width to the canvas. Minor deviations will lead to 1 extra pixel outside, as exported files by Affinity will always have „rounded up“ number of pixels. If you set a stroke of 1.9px, no extra pixels will be added. Visual result is almost what you want

It means how many decimal places will be displayed in the UI, but that has no effect on the actual values used, which is to about 8 decimal places of precision.

It's in 1.10.6 as well.

There are a few other workarounds without rasterizing:

• use Align Stroke Inside only
• Expand Stroke

In case of the Outline Effect, even 1.999999 px width will fix it.

Alright, Thank you guys, I learned many ways of working around this, but I hope they will fix this issue and make it work properly as it should someday, and that I wouldn't have to pay for V3 to get that V1 feature bug fixed.

Hi @Xakiru,

Thanks for your report and our sincerest apologies for the delayed response here. We are exceptionally busy following the release of V2 and we thank you for your continued patience and understanding here.

I can confirm I am able to replicate this issue here and therefore I have logged this with our development team to be resolved in a future update.

I hope this helps
