magic wand selection?

[lettergothic]

I have a simple operation that I can do all day long in Photoshop but I cannot ferret out how to do it in AD or AP.

The help file is, sadly, of absolutely no help, as usual.  :-(

I have a jpg image of a raggedy-edge piece of antique paper. I want the white bg. gone so I have the irregular paper edges on a transparent bg.. In Phshp, I would select the white bg with the (tolerance-adjusted) magic wand, delete it and save the image as a transparent PNG (or TIF). But, there's no wand in AD or AF (that I can find) and the help file doesn't describe how to do this simple operation with another tool (that I can find/figure out). 

Can anyone help?

Thanks!

Affinity Designer does not have one but in Affinity Photo look for the Flood Select Tool in the Photo Persona. It's icon looks like a wand & the default shortcut for it is W (for wand), like in Photoshop.

Thanks for responding!

I tried that tool but no matter how I adjusted the tolerance (down to 1%) it didn't make any diff. in what it selected. It selected way too much. This is an antique, very beige, yellowed piece of paper, very different from the white jpg bg. Yet, the tool still selected lots  of the interior of the "yellow" document—which has nothing close to white in it.  I'm just frustrated; it's so easy with the wand.  Any ideas?

Thanks!

I'm not quite sure what you're trying to do, but if you have an image of yellowed paper on a white background, and you want to erase the background, you could try Filters->Colors->Erase White Paper.

If that doesn't work, can you attach a copy of it here for us to look at?

Edit: Also, make sure you have Document->Transparent Background selected.

Impossible to tell really, without seeing the image but if it selected lots of the interior, make sure Contiguous is ticked.

Not ticked, perhaps?

Yes ticked. That way it won't select the similar colours inside the image.

The OP said "the tool still selected lots  of the interior of the "yellow" document"

With Contiguous ticked, it only selects pixels (of a similar colour) that touch

Ah. Sorry, toltec; must be time to go to bed.
