Cropping / masking image slightly smaller than selection

[AshBoio]

Hey guys,

 

I'm fairly new to Affinity and was wondering if there is a way to crop or mask a selection slightly less than the actual selection itself. What I mean is, when you mask a shape, it leaves a slight layer of the background pixels on your cropped image. I have tried to 'refine' this, however, this does not work effectively enough. Just looking for something which will save me going around the entire image with a small eraser.

 

Thanks very much,

 

Ash

Hi Ash,

Welcome to Affinity Forums :)

Go to Affinity  Preferences, Performance section and tick Use precise clipping. This should help in some situations.

Regarding masking/cropping can you post a sample afdesign/afphoto file so i can see what's going on?

MEB,

 

Could you explain a bit more about what Use precise clipping affects? What is the downside of enabling it vs. the upside?

Hi R C-R,

Take a look at the screenshot below. I've clipped a green shape inside a black shape. The downside is the performance of the program is affected if you have lots of clipped objects.

Hi,

 

Thank you for the reply. I have attached 2 images. One before the cut / mask / whatever you want to call it, and one after. As you can see from the second picture, there are white pixels left from the background. I have tried refining and things but nothing works except goind around the whole image with an eraser. I was just wondering is there an option where you can reduce the selection size of the selected pixels. Sort of squashing them in just a mm or two inside the image to avoid cropping some of the background of the original image. Thank you for your help.

 

Kind regards,

 

Ash.
