Surely..Please..this has to be the most silliest of pop-up questions

[Chris26]

I am continuously being presented with the usual 'wittgenstein' propersitions (as Basil Faulty once said), and the screen shot is below.  Now after 15 years dealing with pixel based, raster files, I am finding that I have to ask the most basicof all questions:  What on earth is this??????  My image is raster, I am n A.Photo a raster based programme, I have only cut out my nice piece of pure Titanium (you should see it bang against another piece of titanium), anyway I digress, I KNOW this is raster, so why keep asking the obvious, and why keep asking even AFTER I have saved the same file 10 times.  Where are those mysterious alien Non Pixel creepy crawlies hiding?  In those little caverns in my titanium perhaps?  Come out come out wherever you are.........

What do you see in the Layers panel?

The Layers panel could contain anything other than a single Pixel object. It could contain two Pixel objects. The message is poorly worded.

Save as *.afphoto file, or other image format, which does not support any non-image information?

Yes, but if Chris tells us what his document shows, we can say something definite about why the message came out.

Like I said, if the Layers panel contains anything other than one Pixel object then the message will appear. It doesn't matter what these other things in the Layers panel happen to be.

Edit: and as @smadell explains below, there might only be a Pixel object in the Layers panel.

I'm going to bet that the original photo (the piece of titanium) from which the non-titanium elements were cut out was a JPG image. Once the titanium is cut out, the surrounding pixels were erased, and that leaves empty space (note the checkerboard which surrounds the titanium). Choosing "Save" asks Affinity Photo to save the image, but the JPG format does not support transparency. Saving back to a JPG will mean inserting white pixels where transparency had been, and the dialog seems like a way to ask "is that really what you want"?

I suggest this because opening a PNG image, erasing a portion of the pixels, and then choosing Save will accomplish the save operation without the intervening dialog. This (I believe) is because PNG supports transparency.

When you open an Affinity Document file or create a new document, the Save command can save to an Affinity Document file only.

When you open an image file (such as JPEG, PNG or TIFF), the Save command can save to either the image file that was opened or to an Affinity Document file.
If there is only a Pixel object in the document when you try to save, the save will proceed without interruption, otherwise you will be presented with the dialog shown in your screenshot so you can choose to save a flattened image to the opened image file or save an unflattened Affinity document.

Edit: and what @smadell wrote in the preceding message

That's a good point and probably the OP's situation. The poorly worded "non-pixels" message really does need to be reworded appropriately for each situation that requires user intervention. I wonder what @Jowday has to say about this

Good Morning Everyone, How ya diddling, and many thanks for the comments, which I am ashamed to say are far maturer and more intelligently written than the manner in which I worded the late evening rant.  (Although Jowday is in a category as yet uncategorized).

The Metal was photographed as a Jpeg.  Immediately loaded into A.photo, and cut out and plonked onto its own layer and a few extra pixels erased via the eraser brush and then Saved.  Now madell's well targeted guess is spot on.  The transparency space is non-pxel.   However as a passing observation I have wondered why, when you go to export as JPEG, not PNG, but JPEG and you have a selection youreally should not have a dialogue box that gives you an option to save without background, rather it should be grayed out, just a passing comment.

Anyway, Non-pixels, Mmm....how about just using that old-fashioned word Transparent areas.   It threw me, and it was late, and I was brain drained.
