Theres white lines that appear after i cut shapes out from Affinite Designer

[Dmaster501]

Hello,

I have seen other forums about this issue and it didnt seem to resolve could i please get some help on this. Even after i export it digitally these irritating lines can be seen with 100% view. I know this has been a big thing with these programs i dont understand how Affinite cannot resolve this issue.

Is this image exported from Designer, or a screenshot of the document on screen? Also, I assume that, in the Designer document, this is a red shape and a black shape on top of a single big blue background. I am right?

I attach a similar composition —I did it very quickly, sorry that the shapes and colors are not perfect. If you compose the image with add, substract, intersect and xor operations on overlapping shapes, you should get no white lines. You can use the Alt key to perform the operations non-destructively. Hope this helps.

Hello @Iltirtar

Thanks for your response so this was from a screenshot. Yes this is a red shape and a black shape on top of a single big blue background. So is this the key press ALT while doing Boolean operations?

I find that sometimes the rendered image may not match exactly with the displayed image in the app, depending on document settings, zoom, etc... But you mention the white lines appearing in the exported file also, so I guess this is not the problem.

I mention the ALT key because it is handy. It allows you to combine different layers with boolean operations while keeping the original layers intact. You just have to keep pressed the ALT key (on Windows) at the same time you click on the boolen operation you want to perform.

But the relevant point was that if you compose the image using boolean operations and the different final shapes overlap (so, red shape on top of black shape, and black shape on top of blue background, you should not get white lines —at least, I am not getting them. You can also do it with one big layer for each color and then applying a mask on each to create the final shapes.

I think it is better you post your questions publicly. That way other people can reply too, and information stays available for everybody.
