Selection inside selection using Pen tool


Recommended Posts

When selection with Pen, Photoshop offers you to select the “Subtract from the selected area” operation, so I can select the field inside the selected area (roughly speaking, make a donut from the circle so that the hole does not stand out and the dough stands out).

Is there a choice for the allocation operation in Affinity Photo? I did not find, and when I select a new area inside the already selected, the “external” selection is reset

Look for the "Mode:" choices on the context toolbar.

Can you please take a screenshot of the menu that you are talking about? Because I use the non-English version of the application and can not find it (in the settings, it seems, you can’t change the language)

You can change the language. It's on the General page of the Preferences, at the bottom.

qaz is using the Pen Tool, not one of the selection tools. Will that make a difference?

I found a life hack: I make an external selection of the object, invert the selected area and perform cropping (this way I remove the entire “background”), and then select the inner area and crop it.

I just thought that Affinity allows you to adjust the selection parameters, like Photoshop (see the screenshot for the “Operations” item)

It does, when you're using a selection tool.

I'm not sure it does if you're trying to select using the Pen, though.

What I do in such cases is ...

  • use the donut shape tool and paint a donut over in a new layer, adjust the donut to the needed circle sizes.
  • Then convert the donut layer into a selection (Selection > Selection from Layer, Shift-Cmd-O), taking over that selection to the underlayed image layer (just select the layer of interest for that selection) and perform the wanted operation with that selection (like delete or fill etc.).
  • This also works for other custom made shapes or shapes made via the Pen tool etc.

Also an interesting life hack :) What you won't do when you don't have the necessary function

Hi qaz,
Welcome to Affinity Forums :)
If you are using the Pen Tool, click/enable the Add New Curve To Selected Curves Object button right before the Convert section (the two white rings icon) in the context toolbar, draw both the outside path/shape and the inner one (that will become a hole) with the Pen Tool then press the Selection button in the context toolbar to convert the paths to a selection. You should get what you want.

With that option enabled shapes/paths added outside the original/first one will be added to the selection, shapes within the original path (holes) will be "subtracted" from the selection. Basically all shapes/paths will be treated as a single path (flattened) object.

And how could I not have guessed that before:7_sweat_smile:. Thank you!
