circlularthinking

If you make a circle in paintDOTnet one pixel thick you get a blurred line, at is tried to spread the top, bottom and sides of the circle over 2 pixels not one... The word is that this is hard to fix, in a previous post the suggestion was to make a 2 pixel with circle twice the desired size and shrink the image, but the result will still be fuzzy if you don't get the pixels aligned correctly both vertically and horizontally, this was an awkward horrible solution... I had found that make the circle 2 pixels thick and using a white circle to cover over half the thickness resulted in a nice result, easier that the other solution, faster, but still much harder than idea... But, as long as you want the circle to be black... I have found the easiest answer!!! Just click on the paint brush tool, and make the paint brush size the size you want circle, it draws a perfect 1 pixel width circle! You just need to take a screen shot of the circle (hit print screen), paste it into a new image, and retrieve your circle! Actually, another way that I just realized is that you can just use the brush to draw a solid circle, then without moving your pointer, reduce the brush size twice and press to paint with the right click or background colour... If you are doing this in a multiply layer this won't even wipe out stuff on other layers and the white won't be seen...

Nah, that's not it. Nothing can be done with that window to make it work right again. Luckily it is not frequent.

I have had I think other variations of this glitch, honestly I don't put much thought into it. Often when this has happened, maybe just because it's how I use mu computer a lot of the time, I will be low on memory, have lots of paint canvases open and have lots of other things open as well. But, now it has happened with few paint canvasses and about half to a 3rd as many chrome tabs as I have at times... The problem, which currently is that I can't select something in one of the canvasses, the function simply doesn't, function. I am copy copy is all (ctrl + A) and paste into a new canvas and then I can select just a portion, but in that canvas, that function simply does not work. I do recall I have had at other time different glitches, one time it was that nothing new showed in a canvas, even though the changes were being applied. Other times I think it has been other things. But this glitch only seems to affect one canvas, or sometimes a few, but never all the canvasses. Heck, I'm starting to wonder if this is more not a glitch but a strength of the problem, after all it's not a single glitch it is many glitches with an easy solution seemingly.

This problem affects me, and I just found the easiest way to solve it with just one extra step! Make a circle with a 2 Pixel width line, then change the colour of the tool to the background colour (or you could even select overwrite and transparent) and make a 2 pixel width circle that is just smaller or just larger, concentrically with the first circle such that it wipes out half the width of the the first circle! This only takes a moment and you are left with what looks to be identical to what you probably would have got with the method Rick suggests, only MUCH easier! I know because I try that at times and it really takes some bother to get things just right. I just checked and the results are very similar, but not identical to the method Rick suggests, the line has the appearance of being a 0.95 pixel width if we are to assume the other method gives a 1 pixel width circle, but honestly it's not a readily visible difference unless you zoom in.

IRON67 has found the right plugins to do this job the best. Follow this link!

Awesome list Iron67!

So, version 1.2.1 at the above mentioned thread has the right feature. If you don't like the way the plugin treats the main image, then you can always put the unadjusted version in another layer and then erase the parts you don't want of whichever one is on top with the eraser set on a 9 hardness so it fades in the difference.

This could help in cases where someone wants to cut something out of a plain background... Sort of like a green screen filter. Heck, maybe there is a plugin for that? Only with partial transparency so it is like the white balance where it's not all or nothing like a floodfill, it can add an influence and not just dominate.

That plugin lives here, maybe a more likely to be safe version can be found there. But I honestly doubt I have a virus. Here is a surely safe version: https://forums.getpaint.net/applications/core/interface/file/attachment.php?id=4503 <Balls! That version does not have the "absoluteblackandwhite" option. So ignore that one!

WTF??? The link, which is a normal link, when I paste it it shows up as "I have a virus on my system"?? If that a warning about that host? Does that plugin source infect plugins with viruses and this is the messageboards way of warning? Or a bad joke? But only the text to the link is corrupted, the link still works, but should you use it? Well I hope the plugin is safe, it works and does a good job. Incidentally, if the source for that plugin can be found, it should not be hard to make an option to make the white or black balance to be an alpha channel transparenct ballance as an option. This would be more useful than just white-balance.

So I thought that there MUST be a better way, and I found it... <snip> I will also attach it just to create another backup of the plugin, but it's brilliant. So what you do is you set the primary pallet colour to what you want to become white, which in this case was the blue aura aroud the lion, you want to get a decently dark shade. Then just open the plugin, for this the default setting of "absoluteblackandwhite" did best. This gave a perfect and effortless result! The next question I percieve is how to best set white as the transparent (alpha channel) colour with partial transparency... I know there will be a plugin for that surely, but I don't know which.

Here is my result, and how I went about it. I used the wand tool and tuned it to select the remaining blue. I used the hue/saturation tool, and reduced it to zero saturation. Then I used curves tool to change the cgrey to white, took a little playing around. Then i used the pen tool on while and zero hardness, this fixed a few areas. This worked well as there was not much saturation in the selected hair, so it's not really missed. But the result was the best way of a few attempts. Obviously it takes a bit if tuning and playing around to find the right setting for each tool.

You are right, I had confused them!

I posted the second comment before I read Ego's method. It is true that for a moment I thought here was polar inversion and polar conversion were the same effect. Thanks, now i need to change my post to the other thread. Thanks again.
