How do I set the aspect ratio instead of using specific dimensions?

[Vophsigem]

I want to export image files using an aspect ratio (ex: 4:5) instead of specific dimensions like 8x10 in or pixels. How do I do this? I have Publisher, Designer and Photo versions 1.10. Thanks

Not sure I fully understand but in APhoto can't you just crop the image with a custom ratio of 4:5 then export it?

Works the same in V1.10 The small cog to the left of the mode setting also lists common ratios you can use.

I don't understand the question. What does exporting using an aspect ratio rather than a size mean? 

Surely it would matter whether the image was:

• 4px x 5px; or
• 4mm x 5mm; or
• 4in x 5in

The desired size of the output is important.

Great, I'll try that, thank you!

You can have any size image you want and you can crop that image to any ratio you want, so you can have a 10in x 8in image which is 5:4 ratio but what if you wanted to have a 16:9 ratio, obviously you are going to lose some of that 10in x 8in but nevertheless you can still crop and export the subsequent image with a 16:9 ratio.

Of course, but it makes no sense to me to say i want to Export with a 16:9 aspect ratio but I don't care about the image size.

But maybe I'm just confused.

Or maybe I am lol! I think Vop is on the right track for what she wants and i'm sure if she hits a problem she'll come back but it never hurts to ask more questions Walt does it.

Yes, you've given me (Tammy) exactly what I needed, thank you!

Also the export window options allows to lock/unlock the aspect ratio.

1. Open the lock.
2. Type the wanted aspect ratio.
3. Close the lock.
4. Type the desired pixel size in any of the two fields.
-> Affinity auto-sets the other field according to your previously typed aspect ratio.

Note, once you unlocked the aspect ratio and typed a different ratio, the exported result will become stretched. From your question ("export") it is not clear whether you want alter the image aspect ratio and thus stretch the resulting image – or if you just want to crop the image in a certain aspect ratio … which would require the workflow before export as shown above by @firstdefence.

Thanks for your response. My question was answered a few above, but this doesn't change the aspect ratio, it changes the pixels or the inches or whichever measuring unit is chosen. Only Photo has the ratio function. There you can choose a 2:3, 4:5 etc. This allows the doc/image to be resized according to a set ratio and not actual pixels, inches, etc. It's a quick and dirty way of creating multiple standardized sizes. A HUGE time saver.

Sounds like you want to try the export persona - look at the options here, 32w, 32h for width and height or 1x,2x for 1 x width and 2 x height ... maybe useful. Never tried these combos and parameters myself though. 

Thanks. This will change the size during a single export, but the ratio is a different function and it's only available in Photo.

I'd rather say you can use various fields (crop, transform, export) to change the ratio. Just consider that an image always has a ratio AND has dimensions, whereas a certain ratio always corresponds with certain pair of dimensions, for instance ratio 2:1 = 4:2 = 200x100 px or 1000x500 px or 3000x1500 px etc …

So, you would type the wanted ratio with an unlocked state of the fields, then lock them to type your desired size in only one of the two fields while the other value will get auto-set according to your previously typed ratio.

To me it is still not clear whether you want to "export image files using an aspect ratio (ex: 4:5)" where "export" would mean to stretch the image if it has a different than your set ratio – or whether you want to crop a part of the image with a certain ratio (and without stretching the image).
