Question Remove thin white line with Paint.NET

[RisingFury]

Usually when I copy-paste stuff into my image, I don't use selection at all.
I copy and paste the entire image, then I use the layers to hide the part of the image that I don't want to be seen. I just color the alpha channel black.

Around the edges, I take a smaller, fuzzy tool that doesn't have a clearly defined edge to color the alpha channel. That way if you color a little bit of your picture it doesn't matter - it's not erased completely, it's just slightly transparent which often works to blend the picture into the surroundings...

I'm attaching the "clean" pics here. The resolution to start with, was less than great, so there is a certain degree of pixelization. Also the first pic is missing half the left foot. (From the original).
I could reconstruct it, but it would be a somewhat lengthy process for a low/medium res pic. If you're not happy with the result, or if you can find an original that is in greater resolution, let me know.

Don't worry about the foot, but there is a problem with the hair, quite alot of the thin parts are missing, such as the part hanging down and the part being blown back, do you think you could fix those up?

You mean like a mask? Can you do that in Paint.NET?

Yes, layer mask. I don't know if you can do it in Pain.NET. It'd be a pretty low blow if you couldn't...

Great idea!
I usually follow a similar procedure to change hair/eye/skin colour and apply make-up on portraits, or even give a "blue-ish" tint on backrounds. It hadn't occured to me that it could be used for cleaning up the edges of a part of an image.

Thanks!

Those parts are 1-3 pixels wide and the method i used has an error margin of ~2-3 pixels. Sure, it can be done, but (for me) it will take about as much time as drawing the thing from the start.

The problem is that your original image is of the chick on a white background. The original image was antialiased to prevent jaggy bits around the character and smooths the transition to the white background. As such, the edge of the chick has already been antialiased and contains almost-white pixels. These are part of the image around the edges of the chick. When you copy her out of the original image, these whitish pixels come with her. The only way to get rid of them is to do it manually.

If you were the creator of the original image (and have it as intermediate layers or images) you may be able to get the chick out of there before she was composited onto the white background. Otherwise there is no simple solution.

Otherwise you could use The Gimp...

I know that, but I don't have the original images, so I can't really do anything about it.

I used to use the GIMP, but it can't use photoshop format and it's interface is completely confusing.

GIMP supports PSD files.

 

[Pyromaniac605]

GIMP supports PSD files.

Then maybe it was .DDS files it doesn't support?
I remember not being able to use a file type I needed for skins.
Either way I still prefer Paint.NET, until I get Photoshop that is.

Here is the Morea pic redone.

That's better, there's quite a bit of the outline, but nothing I can't take care of.
