Edited TIFF files are much larger on V2 than they were on V1

[1250RS]

Greetings,

I just updated to the latest V2. The issue of the file size getting huge when saving a TIFF image is resolved. However now when I save an image the file size gets reduced. It seems to be dependent on what edit is done to the image but the size goes from about 150MB down to below 100MB. l am going back to V1 again for now.

Is this a bug or could it be some settings I have that is causing this?

Thank you.

Welcome to the Serif Affinity forums.

Please explain your workflow a bit. For example, are you Opening a TIFF file, making changes, then Saving the file? Or doing something else?

Hi Walt,

I just tried a gain so that I could provide more specific info.

The initial size of the TIFF file is 148MB. I opened the file in Affinity V2 and just saved it without doing anything else. The size went down to 125MB. I then opened again the 125MB file and did some basic edit (brightness adjustment and then I flattened the layers) and saved it again. The size remained at 125MB. 

 

I hope this helps.

Do you mean you saved it as an Affinity format file? If you opened the TIFF & did not do anything to it, then Save should be greyed out. Are you sure you could use File > Save at that point?

Not true R C-R. 

You can Open a raster image file, make changes, as Save as that same file type.

@1250RS: I think you'll find that using Save, rather than Export, compression will be applied automatically. With Export you have a choice.

But @1250RS said above that the file was saved it "without doing anything else," which I assumed meant making no changes to it.

You can make changes, or not. That doesn't affect whether you can Save. 

When you try to Save, if there are no added layers, it will just save the file over itself. If there are added layers, you'll be asked whether to Flatten (so it can overwrite) or Save As a .afphoto file.

Really? When I open a TIFF on my Mac & make no changes at all to it, Save remains greyed out, just like with any other file that I have opened but not altered in any way. In all such cases there is also no asterisk in the file name in the toolbar, indicating it has not had any changes made to it so I can & do close it without getting the warning about unsaved changes.

EDIT: Try opening this small test TIFF.tiff in say AP or AD 2 but do nothing at all to it besides opening it. On your Windows system is File > Save available? For me, it is greyed out.

Sorry; I misunderstood your question. I'll try on Windows later, probably tomorrow, to see what happens with me.

Not so on Windows, the File>Save is not greyed out.

As Ron mentioned, it seems that the Windows applications work differently for raster image files. They can always be Saved, whether modified or not.

That's my point. I wish it would behave like V1. In V1 I can Save without compression occurring. I'll be using V1 until this is fixed.

Sorry, but no, you can't. V1 and V2 behave identically in this area. If you Open an uncompressed TIFF file, and Save it (not Export), it will be Saved with compression enabled. If you do not want compression, you must use File > Export, and turn off the Compression option in the Advanced Export settings.

I am eating my words, all of them. I am confused since I would swear that V1 behaved differently, but I just checked again Saving the same image from both V1 & V2 and got identical file sizes. So that's settled. Thank you for helping me see what now seems so obvious to me ...

Having said all that, is there any known reason why Saving couldn't be done without compressing? I wish I could just Save without the image being compressed.

There's probably a Feature Request for that, and if not, you could make one in the Feedback & Suggestions section of the forums.

[1250RS]

OK. Thank you.

But I'm curious why you don't want the compression? It's lossless, and unless you have other apps that don't understand compressed TIFF files, it's harmless.

Is lossless compression 100% harmless? I have never been sure of that but I don't really know.

Yes, it is. 

Except, as I said, if you have other apps that don't understand it. 

And I just remembered: it doesn't work well for 16- or 32-bit files. But if you're working in RGB-8 as is must common, it's fine.
