Unwanted outline

Question Unwanted outline
I did a cut-out by selecting around an image,
then making the outside transparent by pasting the selected image into a 2nd layer with transparent background.
Then I erased the original layer.
Afterwards I exported to PNG.

On a second attempt I stroked the outside edge with white, and still the unwanted outline was there.
As kindly suggested by GarryP from the Scribus forums, I also checked carefully on whether I was using any feathering or similar on the selection, to avoid it, but none was used.
The problem seems only noticeable when using a white backdrop for any subject. Only reason this problem doesn't show with the black dot below is because the background is grey. However if you're to use that image in a desktop publishing program like Scribus and import it in, then the default background will be white. Then export it to a PDF file, then the outline I'm talking about should show. You can use the black dot to test it.

Below screenshots show: 1- what it looks like from Scribus, and 2- what it looks like from Adobe Reader, respectively

RE: Unwanted outline
Can you post the PNG with the extracted car, and the original image from which you extracted it (or its URL if it's available on the net)?

You black dot has very rough edges, may I suggest you read this.
