How do I export layers that are cropped to the document in Affinity Photo?


Recommended Posts

Quick Explanation

When I try to export slices created from layers, the output files are not cropped to the document. I can "Rasterize & Trim" each layer to get the desired output, but I'd like a non-destructive way to do it. Any ideas?

 

Detailed Explanation

I'm taking photos of a number of products, each of which have 6 photos of the same size.

My goal is to keep one AFPhoto file per product with each of the 6 photos as layers, with all edits made non-destructively, and then export each photo with a lower resolution (for web) in bulk to a designated "Processed Photos" folder.

Here's my current, problematic workflow:

  1. Open up all product photos as layers in one AFPhoto file
  2. Perform various edits, including rotating, cropping, etc to each layer
  3. Create slices from layers in Export Persona
  4. Set up export settings and export each slice to the destination folder

The problem is that the output files are not cropped to the document boundary as shown in AFPhoto.

I can solve this problem by selecting each layer and choosing "Rasterize & Trim", but this is destructive, which I don't want.

Appreciate the help. I'm guessing it's a pretty simple solution, but I'm an amateur at this software.

Can you provide a sample/screenshot? I always export only what is bounded in the relevant Slice.

Quickest easiest way is to use the bottom layer you already have as a clipping mask for each of the watch pictures. First delete all the slices you currently have then duplicate the bottom layer 6 times and use one for each picture as a clipping mask. Now regenerate the slices by using the layers to slices feature.

I have never mastered color management, period, so I cannot help with that.

Also, if I rotate the image and then add the rectangular clipping mask, I get another issue (see images). How do I solve this? It seems like you somehow solved it with the last file haakoo... (Edit: the example I gave did not include rotations, but in fact there frequently are attempts to straighten the image)

(Edit 2: The rotation does NOT affect the exported file, so this wasn't an issue after all.)

The clipping is the last step in the editing process, do that only before you are ready to export.

Honestly, this is absurd. If I wanted to export all of the layers and ignore the document sizing, crop, and positioning that I've made then all Affinity Photo is doing is exporting the original photos back into new files. That's not exporting layers... that's exporting source images back into new files of the same source images! I cannot believe that such a basic Export Layers function is missing when it is absolutely required by just about anyone working with photography for websites. The Export Persona tool is a weird and complicated side step to make you manually do the thing you were trying to automate... but then it doesn't even do that. It doesn't slice to the dimensions of the document, it just goes back to source for every layer. So why bother "slicing"?. I just can't figure out how anyone thought this makes sense? This is a design tool, not a super complicated graphic format conversion app.

Why cant Persona export just the visible area? 

Welcome to the Affinity Forums

If you're talking about a canvas or an artboard, I understand you. 

If you put the layer in a transparent rectangle the size of the canvas, the slice will also be created in the size of the canvas.
But this could be a solution, for fewer number of layers.

Export Persona, Layers panel, Select layer, Create Slice?

See attachment.  I have 5 layers selected.  When I click Create Slices...  

My slices all have different sizes.  Seem like the only way to get my files to be the size that I created is to export manually.

FYI,  This is a file I created to standardize the file dimensions for a shopping cart.  Each product has up to 5 images.  So I have hundreds of images to export.

 

Doing it manually would be too painful.  Help!

Variant for AP

1. Create a rectangle the size of the canvas.
2. Place the layer in the rectangle.

But it may be difficult or impossible for you if 400 files, each with 5 layers, have already been created.

In this kind of a job you could first create slices in the Export Persona for all 400 layers in one operation and then export all slices in one go to desired resolutions. The resulting PNGs would have the original w/h ratio of each image, but they would have the cropped image at canvas w/h ratio on a transparent background. All the exported PNG images could then be trimmed (transparent bg removed) and rasterized and saved to final PNGs by using File > New Batch Job, and applying a macro:
