Copy reported as document modification

[PaoloT]

Hi,

Affinity Photo v2.5.6 on Intel Mac with Monterey 12.7.6.

1. Open a TIFF file (generated by APhoto).

2. Select all, and copy.

3. Move another document to the foreground, and paste.

4. Move the source document to the foreground, and close the window.

APhoto prompts to save the document, even if nothing has been changed there.

Hi @PaoloT,

I believe this is 'expected' behaviour because as soon as you Select All a 'Raster select all' entry is added to the History panel so even though no changes have been physically made to the source image, in the eyes of Affinity Photo, the file itself has been modified...

[PaoloT]

I would then accept it as an expected behavior. But it still clashes a bit with the common experience (considering copying as a modification is a bit forced; maybe it should just be ignored if no other change happens).

Simply copying does not generate the "Save document" message

It's the "Select all" command that will generate the message

Why do you need to do a "Select all" command, since the tiff layer is already selected once you open the tiff file? Just do the copy.

Note that creating a selection can take a significant amount of work, and some users would not appreciate losing that if they forgot to Save a document after creating a Selection that they might need later to continue their work. So, to me, a warning seems appropriate.

But it's the wrong warning and very dangerous as it lures you into a false sense that you are saving that complex selection

In what way is it the wrong warning? It asks you if you want to Save the document. And if you Save it it will also save your selection, won't it?

Open a jpg/tiff
Make a complex selection 
Close document
Click Save, when you get the warning

All your hard work is lost

Not if the selection is still active when you close the document...

How is it still active?

The selection is still active unless you've deselected it before closing the file... If the file is closed and then reopened the selection will still be active...

Have you tried it with just...

File > Open a JPG
Make a selection
File > Close
Click Save when prompted 

[Hangman]

In which case no it won't if just saving over an existing file, my mistake...

So for that one, it looks like a possible bug in that it could be argued that Save should have prompted you whether you want to Save a layered document (e.g., .afphoto) or Flatten.

I think the issue there is that the Affinity apps have always allowed you to overwrite certain file formats, i.e., JPG, TIFF etc. so if the file only has the base layer it gets overwritten if it has more than one layer then it will give you that option...

TIFF Left | JPG Right
