Affinity Photo 2 Slice tool automation (macros)

[RBeci]

Dear Community,

Is there any chance to create slices programatically, automatically in Affinity Photo. I have to export a picture with different aspect ratios, and It would be the best way to prepare the slices on multiple images (hundreds of files).

I have to do these same steps for hunderds of affinity files: set two slices.

Thanks: Bela

I am almost certain there is not possible using only AP but someone may have an idea of how to do that.

As far as I'm aware this isn't possible I'm afraid.

Not in/with APh.

But it should be easy to do that with some tool like ImageMagick and/or via Scripting in any scripting language. - See for example ...

• ImageMagick
• Extracting a region of an image with ImageMagick
• Extract a subset of an image with ImageMagick
• ... etc.

OH, Thank you so much for you advices!

But It would be great If that would be in AP because after primary placement i have to relocate the slices to proper positions.

Well you also can perform placements/move transforms with tools like ImageMagick, but you need to know the coordinate pixel values where to place things, as there's no interactive WYSIWYG GUI preview for this in this scripting approach.

For APh itself such things could be (hopefully) done in future, once they included scripting capabilities to the tool.

I don't understand that but here's an example using ImageMagick from the command line

magick *.webp -crop 400x300+10+50 +repage -quality 90 -set filename:f %t_%wx%h %[filename:f].jpg

will process all the webp files in a folder taking a slice 400 width, 300 height from X=10, Y=50, you can get these values from Photo after making your slices
then it will save a jpeg at quality 90 with the image dimensions appended to the filename

For multiple slices create a batch file, note % has to be %% in Windows, no idea about Mac eg
magick *.webp -crop 400x300+10+50 +repage -quality 90 -set filename:f %%t_%%wx%%h %%[filename:f].jpg
magick *.webp -crop 200x250+50+150 +repage -quality 90 -set filename:f %%t_%%wx%%h %%[filename:f].jpg
magick *.webp -crop 350x350+100+150 +repage -quality 90 -set filename:f %%t_%%wx%%h %%[filename:f].jpg
