Corgi Posted January 30, 2023 Posted January 30, 2023 (edited) This is in Windows 10 Pro 22H2, using Designer 2.0.4. Hardware acceleration is disabled. Clipping a curve to another curve, and using the Erase blend mode doesn't perfectly erase around the edges -- it leaves a hairline ghost image of the erased curve. The ghost outline also appears in exported files, so it's not just a display problem. This same thing also happens in v1. I also note that if the containing curve has a stroke applied, the stroke isn't erased at all (perhaps this is normal). I know that there are workarounds for this bug, but wanted to report it.

NotMyFault Posted January 30, 2023 Posted January 30, 2023 Interesting. No curves if you keep them as artistic text / fonts. Start to show anti-aliasing hair line when converted to curve.

NotMyFault Posted January 30, 2023 Posted January 30, 2023 can you tell us your workarounds? Those anti-aliasing issues drive me crazy. Some are easy to avoid or work around, others are unsolvable.

NotMyFault Posted January 30, 2023 Posted January 30, 2023 (edited) Ah, in you file the curve in erase mode is an open curve with stroke only. If you expand stroke (Designer), issue is gone. This issue is triggered when strokes come into play -> explains why fonts are not affected because normally you use fill color and no stroke.

NotMyFault Posted January 30, 2023 Posted January 30, 2023 Another factor: the curves of individual layers are merged into one layer. when you separate the curves, group them, and apply erase curve to group, issue is avoided.

Corgi Posted January 30, 2023 Author Posted January 30, 2023 Thank you for experimenting, @NotMyFault. I had figured that workarounds were possible by grouping and applying the Erase to the group, as you did. I also assumed that I could use masking instead of the Erase blend mode for at least most applications. It's a bit frustrating. I've just started experimenting with Designer, and already have run into bugs that I presume the developers would have stumbled upon pretty quickly (like this one). In fact, if you look at the file I attached and just look at the layer curved lettering, I tried doing a Geometry/Add function on it, and the result was horrible. Oh well, fingers crossed for 2.0.5. Although since all three bugs I've found so far also exist in v1, I'm not getting my hopes up. Quote

Staff Pauls Posted January 31, 2023 Staff Posted January 31, 2023 I've added this report ot the issue - our notes state that 'Setting antialiasing to Force Off in Blend Ranges' hides the outline Quote

The issue is that I didn't even use Blend Ranges dialog in this example, so I'd be surprised if someone simply using the Erase blend mode will know how to fix this. Quote
