In Affinity Designer 2 how can I cut out a shape from an image in a pixel layer?

[bobdobbs]

I'm imported a raster image into a pixel layer in Affinity Designer 2.
I would now like to cut out parts of it.

If I was working in GIMP my workflow would be:
* create the shape with the Paths tool
* turn the path to a selection
* with the selection active, activate the layer I want to cut from
* edit->cut

What is the equivalent workflow in Affinity Designer 2?

It's basically the same

What part are you having trouble with or what happens when you try it?

Can you explain exactly what you did? And have you checked the Layers panel to verify that you actually have a Pixel layer, and not an Image layer (which you would need to Rasterize)?

Many!
Destructive or non-destructive, whatever your goal is.

You will need to be certain that the image is actually a Pixel layer and not an Image layer. If you are uncertain about the difference then duplicate the imported layer and rasterize it.

As you are using Designer instead of Photo you will need to rasterize the Curve you made. Make sure there is a fill to the Curve.

In Designer use the Pixel Persona and choose the Flood Select tool on the Rasterized Curve layer, this will select the area of what you have drawn. The Flood Select tool is also known in some applications as the Magic Wand tool.

Now select the "Image" layer and your pixel selection will cut or copy or delete the area in the marquee / marching ants selection.

In Windows you can switch to the Pixel Persona and CTRL+Click the shape/curve's thumbnail in the Layers panel to make a pixel selection of that shape

Does that not work on Macs?

Neat, I learned something. It is Command + Click on Mac. No need to rasterize the Curve.

… anything.
Just nest the image inside any vector object of your choice.
Or create a shape with an opaque color fill and set its blend mode to Erase. 

So many possibilities…

E.g. like this, with live text, non-destructive, all editable:
