Feather function under selection main menu, or "selection refine" options, not affecting rasterized images


Recommended Posts

When attempting to apply a feather to a image, neither the feather function under the main selection menu, or the option under the selection refine, are applying a feather effect of an image that has had the background removed.  Please see the screenshot (planet Pluto, the black box behind is a vector image in a separate layer for clarity).

I have rasterized the image and I am in Pixel Persona.

My system: Windows 10 v. 22H2, Intel Core i7-9700k CPU@3.6 GHz, 16 GB Ram, 64-bit

I've read the relevant helps section and searched You Tube, but I can't figure out what I'm doing wrong, thank you for help -

You can't see the feathering in that screenshot. You would need to make a copy (Ctrl/Cmd+C then Ctrl/Cmd+V, or Ctrl/Cmd+J) and then look at the result.

Example: This is like what you have:

image.png.9e38954ac5f3c7cf54149eb7458e950e.png and here it is after I do a Ctrl+J and examine the resulting layer by itself:

Hi Walter,

Thank you for your quick response, but I'm still messed up.  After making a copy, pasting, and deselecting, the copy I'm left with has no feather, but the entire image has become transparent even when I turn off the black box layer, please see photos, and thank you again for your help

feather selection is not the best approach in this specific case.

You always need to convert this selection into a mask, or use copy/paste, not allowing the easily adjust the radius later.

 

If you want a circular shape with feathered edge:

  • add a circle
  • add a circular gradient
  • set both points to white
  • add 3rd node near edge where you want the feather to start
  • select node at edge
  • reduce color opacity of that node to zero
  • Nest this shape into masking position of your pixel layer
  • adjust the gradient node position to taste / as needed

My posts focus on technical aspects and leave out most of social grease like „maybe“, „in my opinion“, „I might be wrong“ etc. just add copy/paste all these softeners from this signature to make reading more comfortable for you. Otherwise I’m a fine person which respects you and everyone and wants to be respected.

Not my fault (great name ... I'm assuming you had many occasions to use it?)

Thank you for your solution but I have three questions: 1. won't that leave a white halo around the object?  If I want to .png this object and place this object in another project with a busy background or another color, it won't blend in (?) 2. What about a freeform object (not symmetrical geometry?) 3. I'm just starting with Affinity after my DrawPlus program died, and I like the improvements a lot, but if this program has a function that doesn't work, shouldn't it be fixed?  As I recall, I was able to feather any object easily in the DrawPlus FX menu with no problem.

no. It will perfectly blend. Did you try yourself? You don't need to trust my words ;-)

Then you need a different approach.

  1. Duplicate the freeform shape. (duplicate linked to ensure it will update later you adjust the shape)
  2. Add gaussian blur, nested to masking position of duplicate
  3. nest the duplicate to masking position of original layer.
  4. adjust blur radius as needed.

Yes I totally agree. But I'm only a paying customer, not Affinity / Serif staff.
