Stretching pixel perfect solid rectangles (pixel layers) blurs their edges

[Alex_M]

Hi,

I've noticed that Affinity Photo blurs the edges of pixel perfect rectangles (pixel layers, not shapes) if I stretch them even though "force pixel alignment", "move by whole pixels" and "snapping" are all turned on. This shouldn't happen, should it? In Photoshop, I can stretch a pixel perfect rectangular pixel layer (not shape) as much as I want without it getting blurred if the edges are pixel aligned and perfectly solid.

Please check the videos I recorded. One is showing Affinity Photo and the other Photoshop for comparison.

Hi @Alex_M,
This is also a known issue that's already with development. I've updated/bumped the report to bring it up to dev's attention again.

Hi there, is this still in development, or is there a way to bypass this?

Hi @Hevy,
Welcome to Affinity Forums
This is still an issue in the current version (2.5.5). I've bumped/updated the existing report yet again to bring it to the developers' attention.
Regarding workarounds it depends a bit on what you are trying to do. Are you trying to extend a background of an image, extending part of a gradient of an interface element,  other use case?

Only by adjusting your workflow.

Either use vector shapes as long as possible while resizing layers.

When using selections in pixel layers, never resize or move „in-place“ of that layer. Instead duplicate selection, then resize/move as separate layer. You can then add a curves orvlevels adjustment to clamp alpha to 0 or 1.

Another option is to use bitmap fills or pattern layers. Those allow to choose the resample method (nearest neighbor will avoid).

another trick is to scale up by factor 2 or 3, then rasterize. If you reduce the size to target, no edge blurring occours.
