Rectangle Selection & Refine - Rough Edges


Recommended Posts

Hey guys, 

New to Affinity Photo on iPad, but confused as to why when I select an image without a feather with the rectangle selection (which has very straight lines) and go to “refine edges” I get this fuzzy, sloppy edge. 
 

I checked every setting I could to ensure it wasn’t some type of feather occurring. Help?

Hi, to feather, just use the feather function instead of refine. This completely avoids the issue you observed.

To find it (middle left edge), press and hold the question mark at the lower right edge.

 

PS: i may misread you question. What in first place do you want to achieve with the selection?

The refine tool is a powerful but tricky beast, and if you want clearly defined edges it is not the best weapon. It will mainly apply additional matting (soft edges) as first step when just activated. 

  • what part of the image do you want to select?
  • what type of edge to you intend? Soft/hard, smooth/sharp, …?

Based on your image, the magnetic lasso might be better suited, as it guarantees shard edges.

My posts focus on technical aspects and leave out most of social grease like „maybe“, „in my opinion“, „I might be wrong“ etc. just add copy/paste all these softeners from this signature to make reading more comfortable for you.

I just simply want to crop this photo to the smaller selection with straight sharp edges and corners. I don’t get why Affinity makes this simple task so difficult… on desktop it’s not this complicated. If you’re sue to photoshop, you simply use the rectangular selection tool, make selection, invest the selection and delete.

Then why are you using the selection tool?? Simply use the crop tool if you want to crop the photo.

Have a quick look at the help file, under Crop tool. The Crop tool makes a simple task such as cropping an image really 'simple' 🙂

Photoshop process is ‘destructive'. Affinity's editing processes are generally 'non-destructive', unless followed by rasterising. That includes cropping. So If you are coming from a Photoshop background you will find many differences in the way things are done.

The crop tool crops the entire canvas, no? I want this cropped while within a canvas full of other objects.

Then use rasterize & trim - affects one single layer only.

Actually, the best way to go would be using a rectangular vector shape used as mask layer. All is well documented in help & tutorial videos.

Thanks for everyone’s assistance. Odd this feature isn’t just built in. It’s so simple. I’ll use masks as @NotMyFault suggested and deal with the hidden edges and stuff I suppose. I prefer a cleaner interface and less clutter but may be something I get use to.

Ok I understand OP just wanted to crop the image but can anyone answer on how to get clean edges from selection & refine? My edges look exactly like they do in OPs 2nd video they posted.

If you want to create a selection with many straight edges, do not use the selection tools. Instead use the pen tool set in smart mode and dab dab dab around the object then double tap on the first node to complete a closed curve. Use the node tool to reposition the nodes adjusting any curves or sharp corners using the node tools. Delete any unnecessary nodes. Once you have created a good sharp outline around the object, select the pen tool again and then convert to selection on the toolbar.

This makes the edges look better a lot better but its time consuming. Like what if I want to select a person or a more complicated image, why does AD and AP create this hazy edge?

The Refine tool is designed to hunt out fine details for hair and fur as the help section shows,

https://affinity.help/photo/English.lproj/pages/Selections/selections_refine.html

I would never use it for straight edges. Using the pen tool method would be time consuming for hair and fur but once you get some practice it can be very quick indeed, fewer nodes is better, don’t try to be too accurate as nodes can be adjusted easily. A rectangular shape only needs 4 nodes with sharp corners. You can even use a shape like the rectangle, position and size it more accurately than you can the rectangular selection tool and then tap pen tool to change to a selection.

Another issue to add to this, very odd “refine” behaviours on Affinity Photo for iPad… I have a super clean selection and then I “refine” and it makes parts transparent. What??

 

To avoid the transparent sections, designed to handle hair and fur, on the refinement tool make sure the border is set to zero. If you use the matte black then adjust the border you can see the transparency sneaking in.
