Advanced Rotate:

This plugin does rotation on the selected area.
A great advantage is this rotation plugin operates around the center of your selection as compared to Paint.NET's rotation plugin which always uses the center of your whole image.
The main purpose is what to do with the unauthored areas of the rotation....
I.e. you can select to mirror the image, clamp it, use the default colour, leave it as untouched, and repeat. Mirroring is probably the most useful for general photo tidying as it fills the area with appropriate pixels as you can see below...
It is also possible to turn on/off the bilinear interpolation should it get in the way or you want a faster update on larger pictures

Here's a picture of it in action.

Here's a Vignette plugin I've made using CodeLab's C# tool.
 Vignette1.zip (4.59K)
Number of downloads: 517

Details
To use this you need to create a new layer and select the effect on this newly opened layer (top most). It will generate a smooth shaded border as seen in shows like TopGear and other motorsports. Also excellent to bring the viewer into the center of the picture/give the feeling of claustrophobia :)
The effect is added to the Effects/Artistic menu option.

i like the vignette one
was always searching for a vignette effect in a new layer ;)

[Briamoth]

Like the vignette one too. Would save a lot of time when making some of my sigs. Thanks a lot man!

iPhone TabBar Icon Maker

Download here
 iPhoneTabbarIconMaker.zip (4.37K)
Number of downloads: 184

Details
For any iPhone app makers out there you may have found making icons a bit tricky with Paint.NET. The magic is you need to use only the alpha channel, as the RGB is discarded by the iPhone and save the image as a 32bit PNG.

This plugin will sample the luminosity of your image (RGB value) and convert it into a greyscale (or you can author it in greyscale if you'd prefer).
It will then set the greyscale into the alpha channel and set a user selected RGB value so you can visually see the icon in editors.
Transparent areas will be transparent on the iPhone (i.e. showing the tab bar). Opaque areas will show up as light colours.

Icons need to be about 20 pixels high and no larger than say 40 pixels wide.

This plugin will install itself into the Effects/Advanced menu item of Paint.NET

Here's an image of it in action (using an image that is much larger than 20 pixels high so would need to be downsampled).

Cheers,
Stu

One suggestion: Put everything in the first post and possibly in the same ZIP so that they're easier to find, especially if you release a new plugin after a lot of comments.

RGB remapper

Download here
 RGB_Remap4.zip (5.22K)
Number of downloads: 236
This was done to help test tinting for fullscreen effects in movies and games.
It will add the menu option to Effects/Colour/RGB_Remapper.

Effectively it runs the RGB value through a matrix to remap to other colours so you can convert your Red's to say Yellow but leave Green and Blue channels uneffected. The alpha channel is untouched.


Details
To use the orthogonal matrix just set the Red value to Red, Green value to Green and Blue value to Blue... this should produce exactly the same image that you see to begin with. From there you can start tweaking the colours to remap the RGB channels to other colours. Very handy for swapping the Blue and Red channels around for instance but equally very helpful for matching skin tones from different lighting conditions or media.
There is a normalize option enabled by default (check box), disabling this means you'll get a non-normalized matrix so you can do things which aren't technically accurate but give good effects like replace the red and blue channels with say dark grey so you'll only have shades of grey and green in your image (used heavily in films like Matrix).

This will be useful. Thanks! :D

Looks very interesting. I'll give them a try. Thanks !

Here's another very simple but somewhat handy plugin. I've coined it 'Alpha Contrast', it can really help get a good sharp edges after gaussian blurring something with alpha in.

(Thanks again to CodeLab for making this trivial)


What it does is a value of 100% leaves the picture untouched.
A value of 0% will make everything have 50% transparency.
A value of 100% will leave the alpha in the picture untouched.
A value of 200% will make any source alpha at 50% remain at 50%, src alpha at 25% will become 0% and src alpha at 75% will become 100% opaque.
etc..

The equation is
New_Alpha = ( Original_Alpha - 0.5 ) * Percentage_To_Apply + 0.5

Here's a few steps of it in action...


Attached is a zip will all the plugins so far.

I like the alpha contrast one and adv. rotate. I could see using alpha contrast as an AA tool ... Applying Feather/GBlur/AA's assistant then alpha contrast to sharpen out the blurry effect those plugins give it

[RedFalcon]

Very interesting plugins. Thanks!
