I am sure that merging raster layers in application that deal with raster content should not be the cause of loosing information in both images that you merge by default. I can't imagine realistic work scenery when it should go the way it goes in AP now. Of course you can raster all layers every time before marge them and it helps but it not looks like normal workflow isn't it?

I agree with you, the way it works at the moment is frustrating and unintuitive, especially when you're new to it. Something shouldn't change in appearance when merged, full stop.

However, there are workarounds and I'm working fine with merging layers with no pre-rasterization at the moment. I'm not resizing or transforming content though (other than 90deg rotations). It's very finicky about snap settings.

The conclusion with this issue: I need to concentrate to creativity, not on "rasterizing layers", I don´t need to even think about it. This whole idea of rasterizing and "wannabe non destructive editing" is stupid, because all of this leads to destructive editing on a pixel level. Thats a pity that Affinity isn´t still alternative to Photoshop to Pro users. Affinity is maybe good for common photo editing, not for pixel precise art yet. I will be back in half year, and maybe Affinity team will make something about this.

I need to merge down images onto one layer. It is not a stack of images that merge on top of one another but instead the images lie side by side.

I was shocked to see that merging process creates a blur. I was not aware of this until I zoomed in closely, but that was after hours of work.

Doing a search I now see others experience the same problem. And it's not a small one.

I really want to like Affinity but between the bugs and quirks the program can be trying.

Hi @ronald618,
Welcome to Affinity Forums :)
Were the images pixel aligned (that is, their X,Y coordinates and width/height were integer pixel values)?
You can check this clicking on them with the Move Tool (on canvas or in the Layers panel) and checking them in the Transform panel. You may have to increase the number of decimal places displayed there going to Affinity Preferences, User Interface section, Decimal Places for Unit Types, and increasing the Pixels value to 3 or more. There may be other causes for the blurring - do you mind attaching the file to be checked?

Thank you for your reply.

This is a detail of the document.

Merge the top layer down while zoomed in closely on one of the images. You will see the blurring.

Neither of your pixel layers is aligned to the pixel grid. Here's what the Transform panel shows for the top layer, when the document units are switched to "px":

From the UX perspective everything should work in integer pixels by default.

And only those who want to mess with this sub-pixel technical details should be able to turn this feature on.

Or we should have a document workflow setting to choose between "Pixel-perfect workflow" and "No pixels workflow".

In any photo editing program...PS, Gimp, Photopea whatever...the simple act of merging layers causes no loss of quality. 

It would never dawn on me to fool around with pixel alignment.

I lost hours of work with this. 

Sefif has very slick advertising, but the program is not designed for professional work.

Agreed.

As I mentioned above, even if you have things all set up correctly with 'pixel snap' on some other setting override this and give you fractional pixel placements anyway. Once you know what's going on you can figure stuff out but it's controlled by far too many individual settings at the moment and many of the settings conflict with each other.

To say the app is 'not designed for professional work' is absolute nonsense though. It's excellent, as is Publisher.

A pro workflow should be designed with as few clicks, surprises and interruptions as possible. Time is money.

The software is very low cost and the company is offering months of free use so they deserve praise and understanding for that.

Affinity Photo will get there but let's face it, it's not there yet.

I agree, for example if you are working in 3D, you simply find that in 3D there are more complex problems that you can´t even imagine in "simple" Photo software. You don´t need waste your mental energy to concentrate on things like "I have to rasterize it every time, I have to rasterize it every time". Why would I do that? I don´t have time for this, I rather spend my money for software where I don't have to deal with such trivial things. I hope that Affinity will do something with this issue in near future.

I think this new update solved the issue.

Sadly, it didn't.

merge-blurring.png.bbde2a7f1600738ea67363a5abac7510.png

left: three layers "merged down"; right: the exact same three layers "merged visible".

I read both related threads but can't make heads or tails of why the left image turns out blurry while the right one does not.
Ah well, as long as I remember to never use "merge down" I'm fine. AF is good tool despite some quirks, but what software doesn't have those?
It's affordable and no subscriptions. I'm glad it's there, especially now Gimp and Inkscape have become unusably slow on Mac OS.

 I tested very poorly to be honest, I just merged lots of layers gradually and couldn't see any problem, but I'm glad you posted so I'm not gonna work with Affinity Photo until they fix that 😅.

Thanks

Hi @Andrea Andrea,
Can you be more specific regarding the fix you are expecting please? As long as the layers have the same dpi and are pixel aligned they should merge without causing any blurring. Can you post a file/example where the merge operation blurs the output/result for inspection please? Thank you.

Affinity Photo is the only photo editing program that I have ever encountered that requires you to be concerned about having pixels aligned for the simple act of merging down.

We're in the year 2021, not 1995.

I worked long and hard on a project when just starting out with Affinity...only to realize the blurring upon close inspection. It was HOURS of work ruined.

If Affinity is going to insist on keeping this absurd quirk, then there should be a pop-up warning explaining the blur.

Maybe intentionally

Affinity leaves it to the user if he needs pixel-alignment or not. Both have totally valid use-cases. 

Affinity cannot distinguish between them or what the user intents. There are uncountable more functions where some users might need a warning. Other users may hate warnings unnecessary for them (e.g when closing Develop Persona). 

I share your frustration learning that you wasted hours based on app behavior that seems unintuitive to you. But maybe it isn’t Affinity to blame.

This I think is as it should be for all apps -- if nothing else, there is no way for a programmer to know if I would prefer for the position or size of anything to be rounded up or down to a whole pixel value.

What would be a case where such blurring when merging down would be desired?

For similar reasons as we have

  • blurring and sharpen filters
  • resize with up or downscale
  • convert between 8/16/32 bit in any direction 
  • convert between color formats in any direction
  • B&W / threshold  adjustment/ posterize filter and recolor / gradient map adjustments
  • different blend mode categories
