Transparent background

[Signguy]

When using Pages on the Mac, there is a feature called instant alpha that can remove the white/colored background from an image and make it transparent.  Is there an easy way to do this in AD or AP? AD Prefered.

 

I see that in pixel persona (I usually only use draw persona) I can use the Selection Brush Tool and then I can just delete the selection.  However, I can't seem to get rid of the yellow edge around the flower as well as Pages instant alpha can.  Any suggestions?

Hi Signguy,

In Affinity Photo you can go to Filters ▹ Colours ▹ Erase White Paper to remove the white background.

In Affinity Designer those filters are not available so i would create a mask (attached to the image layer) to hide the white background.

There's several ways to do it, the easiest is probably to use the Selection Brush Tool to create a rough selection of the flower then refining it, selecting mask as the output.

That worked great MEB!  I was selecting the white background and then deleting it. It still left a slight yellow border around the flower.  I never thought to select the flower and then masking it.  There is a lot to that refine option that I just don't understand but I'll keep playing around with it and trying to find some documentation on it.  You gave me a great start.  Thanks a lot.  The erase white paper in AP worked too but still left that slight yellow line around the flower.

Here's a video (for Affinity Photo but the Refine dialog is exactly the same) that may help.
