Random white stroke on some borders when exported

[Mitch2024]

Attached are a couple of exports - see against dark background to see some side have what looks like 1px white stroke - totally random - can be on different sides.

Not in the design and a real pain.

Please add to bug list.

It is Pixel Perfect? - position and size is whole pixel?

Hi @Mitch2024 and welcome to the forums,

1. Are you exporting your file to PDF?
2. Does your Affinity Document include Bleed?
3. Do the images and solid colour fills extend into the bleed area?

There is a known bug, with PDF exports, logged under AF-1340, where the exported size sometimes exceeds the document dimensions which can result in 1 px white borders... to avoid this add a 3 mm bleed to your source Affinity document and ensure any elements that run right to the page edges include bleed... this will negate the white borders on the exported PDF file...

Yes whole pixel retina.

1. No these are for web so jpg

2. No bleed

3. colours and images extend well outside the artboard boundary

It sounds similar to the PDF bug - but on jpg - I have been working round by putting everything in a rectangular mask and exporting with a couple of pixels margin in PNG transparent - not ideal

What are your document dimensions and the dimensions of the exported file?

Ah - good question - I think you have solved it - artboard 1080 x 1350 px, but in Export persona has added 1px.

Manually correcting export persona size solves it.

I don't know if this is something I have done inadvertently or not - but seems random across multiple artboards and files.

Is this also the case when you set the decimal places to six under the Affinity Designer User Interface Settings, i.e., does your Artboard still show integer values?

yes still showing integer values - but for new artboards consistent between design and export personas - so I should keep at 6 decimal places?

That shouldn't be necessary... but while still showing six decimal places, check that the Artboard itself uses X and Y Integer values for the Artboard's position...

current artboard X & Y are showing decimal places until I type in an integer, should I ensure integer only X & Y, H & W ?

Yes... doing so should ensure your exported JPEG is exactly 1080 x 1350 px...

That's no problem at all, hopefully, you'll have perfectly exported JPEGs from now on...

Yes - only this is Pixel perfect.
