Clean edges when resizing


Recommended Posts

Hello!

I have cut out an animal from a background so I can use the animal on whatever background I choose. The original image is about 3000x2000 px. When I've made the cutout I would like to resize the image to about 300x200 px. The problem is that all the edges on the animal gets transparent and I need to have pixels with 0% transparency.

When I used Photoshop before I could control this in the resizing options but I can't seem to find it in Affinity Photo. Anyone who has a clue how to do it?

I've tried all the different resample options but no luck. Look at the attached screenshots to see what I mean.

Unfortunately there's no equivalent option for this in Affinity Photo when resizing, however there may be a workaround for this workflow.

Could you please provide a copy of your .afphoto file before resizing so I can investigate further here? Many thanks in advance!

Please note -

I am currently out of the office for a short while whilst recovering from surgery (nothing serious!), therefore will not be available on the Forums during this time.

Should you require a response from the team in a thread I have previously replied in - please Create a New Thread and our team will be sure to reply as soon as possible.

Many thanks!

You can use the ‘Coverage Map’ control to remove the antialiasing:

 

I try to set it up just like the instructions but I have no change in antialiasing. Well I have change but not to the better. Still no sharp edges.

Thanks for your file, I too have been testing multiple methods including the above one Alfred has linked to and unfortunately I don't believe this is possible.

When you resize the pixel data it is resampled and this causes the semi transparent pixels you're seeing, currently there's no way to change this - my apologies.
