To get a transparent background

[Nadar]

Hi

 

I'd like to have a picture on a transparent background on a layer because I want to put it on another picture on another layer.

I cropped my picture with the lasso but now what should I do to make the background transparent ?

I inverted the selection.

I cut.

But the white area stays !

Thank you

edit I also exported the picture in PNG but it still with a white background when I import it in Affinity…

General idea:

Open first image. Place second image and hide layer.. Ensure both layers are pixel (rasterise if necessary).

Use selection tool to select wanted area in one image. Finalise selection and output as new layer. Hide original layer. Select new layer and unhide the placed layer. Use move tool to finalise position.

Thanks a lot DM1 but I don't see how that can remove the white background for a transparent one…

The cutout won’t have any background. If you want to remove white background from placed image use the Erase White Paper filter in All filters menu list.

Make sure you have turned on Document->Canvas->Transparent Canvas otherwise the background will appear white and not the checkerboard pattern.

Hi both of you

and thanks

 

If I cut or move the selection, the pictures remains !

document is transparent, white paper has been erased in the filters 

the picture is jpeg

if I rasterize the issue remains with a difference (white area)

Did you do as I suggested. Let me show you what transparent canvas toggle does.

Thanks Paul …

 

I tried to do as you do but after having create a selction woth the rectangle tool when I cut the area selected instead of having a white rectangle as you get nothing happens !

Here is a screen video it a little long (I am not used to it) but, please, be patient :

Try using the smart selection brush tool to get a better selection. Use add /subtract as needed and refine then output to selection. Switch to Photo persona and long press screen tap delete to remove sky. Change canvas to transparent to see the effect.

Wrong tool. The attached example is rough as it’s low resolution image and no clear edges to select but you will get the idea.

Nadar, it would help if you pinned your layer studio open as shown in my video, as you do the steps. I suspect you either do not have the correct layer selected when doing the cut and/or your layer says "image" not "pixel". If it says "image", then rasterise the layer first and repeat.

Hi

Thanks so much for involvement.

Here on a screenshot is a try and I have two questions about it :

-How can I remove the first background (up) it is stuck on the cropped picture of the statue ?

-The statue on the second background (lower) is transparent, why ?

1. You can delete your top layer by selecting it in the layer panel then selecting the waste paper bin just above it.

2. Please watch this video

Thanks Paul 

I rasterize the layer but the issue stays.

If I delete the first layer the cropped picture of the statue disapear because it is a part of it…

Nadar you are simply moving the selection within the existing layer. You have missed an important step in the process.
After making a selection you need to go to the bottom context menu, select refine and output as new layer as shown in my video. Then you can delete or untick the old layer.

Thanks a lot DM1

When I do that there is still an issue

as you can see half of the statue is covered by a part of the background :

Nadar, it appears that you are still not correctly outputting to new layer, as the original layer shows a 'cut out' of the selection. 

Start from the beginning using the original image. Select , refine, set output to new layer and tap accept. Your original layer will be unchanged, your new layer will be the selection.

Don’t drag the selection, just move the new layer as below.
