DarkClown Posted June 29, 2020 Share Posted June 29, 2020 The Gaussian Blur (fx) doesn't work properly on edges of the document. Seems like it uses white or other available bg data to calculate the edges of a layer. This leads to nasty effects on the document edges in practical use. To demosntrate the probelm I use a single black layer, add gaussian blur with the (fx) function and increase the parameter to half and max. I would expect nothing to happen ... but regretfully the edges are screwed. In practical use it is impossible to extend gaussian blur to the edges: Assuming you will declare this bug to be a feature, I'd like to know how to overcome this "Feature" since I need different results. (BTW: Photoshop handles gaussian blur on a smartfilter the correct way ... in your words: they have not implemented this "feature" until today *G*). Just for competitive reasons: I'd love to see a way to disable this feature.

Staff MEB Posted June 29, 2020 Staff Share Posted June 29, 2020 Hi DarkClown, Tick the Preserve alpha checkbox below the Radius slider. That's exactly its function - "fill" in the borders of the canvas. DarkClown 1 Quote A Guide to Learning Affinity Software Link to comment Share on other sites More sharing options...
DarkClown Posted June 29, 2020 Author Share Posted June 29, 2020 Great! Thx! May I ask what's the benefit of disabling the "preserve alpha" function?

Staff MEB Posted June 29, 2020 Staff Share Posted June 29, 2020 There's cases where you don't want it enabled so you can get the edges of an object feathered for example to create a mask, to simply soft the edges of a picture on a design/layout or even to help with the shading on a illustration (by applying gaussian blur FX to vector objects). There's plenty mores uses but those should give you an idea. Quote A Guide to Learning Affinity Software Link to comment Share on other sites More sharing options...
DarkClown Posted June 29, 2020 Author Share Posted June 29, 2020 Thanks for the explanation. May I suggest to have "preserve alpha" enabled as default?

Staff MEB Posted June 29, 2020 Staff Share Posted June 29, 2020 Hi DarkClown, I'm not sure there's a logical default option here. Depending on user's background both choices seem to be adequate/sensible, but feel free to create a new thread in the respective Feature Request section asking for this to be the default. It's not really up with me to decide it. Quote A Guide to Learning Affinity Software Link to comment Share on other sites More sharing options...

It's highly unlikely to be changed now but people have been asking for "sticky settings" for years now so it may be able to be made sticky in the future Quote To save time I am currently using an automated AI to reply to some posts on this forum.
