Trim Transparency in Affinity

[Zbigg 23]

Thanks for reply.

Got both, Photo and Designer but for obvious(?) reasons try to get familliar with Photo as possible PS (here: CS5) replacement.

I am familiar with sc. 'paper space' and sc. 'model space' per CAD soft analogies but-have to admit-had no idea it may exist in PS.

How could I check/verify that oversized layer /in PS?/ ?

I’m not familiar with the abbreviation ‘sc.’ Perhaps you could expand it for me and others.

So-called. New invention perhaps?

Does it bring any enlightment to the real problem?

In Affinity Designer you can use Artboards as a pseudo trim transparency.

1. Select the artwork
2. Select the Artboard Tool
3. Under Size: Select Selection in the Artboard Context Menu, which will appear above the artwork and below the main toolbar.
   
4. Click on Insert Artboard

Well, thats ok but I expected to work with bitmaps in APhoto rather than vector program?

Can I correct it in APhoto? I just only need trim by transparency...

mentioned it for all the +1 transparency trim voters for designer to give them a workaround for now. Toltec mentions this in his post prior to mine, I just went into more detail.

It would be helpful for you to make a simple design that you would normally do in order for people to try and find a workaround for you or a workflow that would be more beneficial.

Just for laughs...

1. I created a document in Adobe Photoshop CC  and a similar one in Affinity Photo
2. I created a simple brush 100px in each app and started with RGB Red (255,0,0) Hardness 0%
3. I made guides that would place the brush centres at X: 150, 300 and 450px and Y: 150px 
4. I made 3 brush dots with a single click with the mouse using Hardness 0%, 50% and 100%
5. I then used trim in Adobe Photoshop CC and Clip in Affinity Photo
6. The document size for Adobe Photoshop CC = 481x159px
7. The document size for Affinity Photo = 396x99px

This is quite a difference, Affinity Photo crops quite aggressively to the 100% hardness dot but the antialiasing is better in Adobe Photoshop CC and gives a smoother effect than Affinity Photo

Definitely +1

Document > Clip Canvas

Absolute +1. Just fired up Photo to finally get at moving to it from PS for major work flow. First image need Trim>Transparent, end here, and am again running PS. Really, really want to change, but the "workaround" while feasible add just enough time to accumulate very sig total with dozens and dozens of images to process.

+1 Trim would be nice, or just give Clip some options: Clip the top-left pixel color, or all transparency (including hidden content).

My workaround, for now, is to select & copy what I want to trim, then File > New from Clipboard

Mods: Clipping transparency, even if there are hidden contents, would be really nice in my workflow. It's destructive, but I bet loads of people use it for the same reason as me. I Trim temporarily for exporting individual layers for games, and then undo. I even have a macro in PS for hiding all, unhiding the selected layer, and trimming. I do this by hiding all the layers I don't want, and then Trim.
