Artifacts/Outline when resizing transparent layers - X6

[DeltaAlphaBravo]

Hello,

I'm getting an unwanted effect whenever I resizing an image that has layers with transparency. Upon resizing an image; any layers with transparency gets nasty looking outline around whatever is in it.

I'm not a professional so forgive my ignorance. I don't know the jargon to help describe what's happening. the best way is by showing you screenshot of what I'm seeing:

Here's a image with a white (#ffffff) background layer. It has another transparent layer on top. In this layer I have put white text "hello world" and hand drawn three white dots.


As expected: all you can see it a white image. You can't make out where the text and dots are because they are the same colour as the background.

I then shrink the image using 'Image->Resize'. Afterwards I see this (using all resamples apart from pixel resize):


You can clearly see the text and dots because they have been outlined.

I used the example above to reproduce what I am seeing. But this outline appears if the background is transparent too. Or if it's a different colour.

What am I doing wrong? How can I stop this unwanted outline?


Thanks in advanced

I just tried it and got the same result that you did.

I also tried it in PSP8 and got no outline.

I got this in X4:

I have found that if you modify your selection by 1 pixel (600 x600 image with text 96 pixels) then the effect disappears.
