Only 3 out of 10 FX have no blend mode. Please provide an example Affinity document with the problem so we can investigate and, hopefully, offer solutions.

To emulate Preview resizing in Affinity Photo: open an image file in Affinity Photo document convert format to RGB/32 document resize with 'Lanczos 3 (separable)' resampling document convert format back to original (for example, RGB/16 or RGB/8)

Yes, the slippery handles have plagued me since the beginning of v2. Has been reported before. Worked perfectly in the v1 apps, so surely cannot be too difficult to fix.

File > New From Clipboard Edit: that's Affinity on macOS

Maybe a glitch in the Matrix

Same on macOS 12.7

Much of the design is being rasterised with a white background because the two Warp Groups have Erase blend mode. Erase blend mode is not supported by export formats, so rasterisation is required to maintain the appearance of the design. Now you know that, you probably realise a solution is clipping or vector masking, but ask for help if you get stuck.

A simple solution is to ctrl-click with Node Tool to delete the path segments that lie across the ends of the 'S' shapes, as shown in the video below. delete segments.mp4

Yes, I found that earlier, but different pages feature the image with different saturation levels, and so it would be best if we had the OP's file.

The forum software messes with uploaded image files before displaying them, so pease zip up your iStock sample image file and screenshot then attach the zip file in a new comment.

Absolutely yes. Your screenshot shows Affinity displaying the iStock image file correctly on your machine. I was talking about the OP's attachments (screenshot and image file) in a correctly colour managed browser and when I open the attachments in other colour managed software on my Mac. These attachments show the image being displayed wrongly in Affinity on the OP's machine for some reason.

In the screenshot, the Adobe display is the one that matches the image file. It's the Affinity display that looks wrong.

An extremely valuable tool in Designer is Point Transform Tool. (As with all tools, look at the hint line at bottom of window for keyboard modifiers.) The video below shows a shape being snapped to another shape, but it also works with Curve and Curves objects. PTT.mp4

Set red value to 0 where red value is less than r (8-bit integer): R = stepn(R, (r - 1) / 255) * R

OK, I was talking about the case of a flat raster image simply opened in Preview and Affinity. Such as that TIFF supplied by the OP. I have no official source and go by empirical evidence. Experiments are easily designed and carried out.

Colour differences when resampling 8 bpc or 16 bpc image in Preview versus Affinity: Preview uses a linear colour space for resampling to the display resolution or export resolution, whereas Affinity uses the gamma-encoded space of the image. When Affinity is at full scale (100% zoom) and Preview is at full scale (100% on a 'standard' resolution display, or 50% on a Retina display), they are not resampling to the display resolution and they look identical.

Doesn't surprise me at all.

You're welcome:) In my opinion, Preview does profile assignment correctly except for the significant failure to display the change in appearance during the editing session.

Same here. Maybe the forum software could be updated to automatically convert MOV uploads to MP4 with H.264.

There won't be an option to Revert if nothing has changed. Soft proofing is just a view in the app, not a change to the document. Actually assigning a profile is a change. Tools > Assign Profile... It's just going to confuse you and lead to a nightmare of a thread, so maybe better to leave it alone.

When you close a file, there is an option to Revert which restores the file you had before editing it in Preview. But I think I get your point. When I wrote "without saving the file", I should have written "without closing and accepting changes to the file". Anyway, if Apple hadn't broken the live display of a profile assignment in Preview, this discussion wouldn't have been necessary.

Of course you don't if you close (and save) then re-open the file. As I said, "it restores the open image's profile to the one in the file after you experiment with assigning others without saving the file. The bug I mentioned earlier - the failure of the effect of a profile assignment being made visible - can make all the profile assignment functionality confusing." If Preview was correctly instantly displaying the effect of a profile assignment, you would clearly see the value of Existing Profile as a profile reset while a file is open.

It does have a function; it restores the open image's profile to the one in the file after you experiment with assigning others without saving the file. The bug I mentioned earlier - the failure of the effect of a profile assignment being made visible - can make all the profile assignment functionality confusing.

No you are still misunderstanding the dialog in Preview. Existing Profile is not a heading; it is just the very first choice in the list. ACES CG Linear is just another choice - it happens to be the first in an alphabetical list of available profiles underneath Existing Profile. If you want to see the name of the existing profile, press cmd+I for info about the image before assigning another profile. cmd+I in Finder will also tell you the profile for many image file formats.

No, Preview really does do assign, not convert. However, you need to save and close the file then re-open it to see the appearance change. Years ago, the assignment instantly became visible, but Apple broke that.
