  1. This effect is similar to the Photoshop's Dynamic Contrast filter and allows you to create images with high contrast. You can find this effect in Adjustments menu. DynamicContrast.zip Amount - the range of adjustment of contrast. Threshold - sets the threshold for enabling a color (and its shades) or a mixture of colors in the Blue -> Red -> Green direction. Intensity - sets the pixel intensity of the image. When Amount = 0, the Threshold and Intensity controls have no effect on the image and are therefore disabled.
  2. Even though I have done this sort of thing for G'MIC-QT as a cli command, I decided to make it as a plugin just out of doing something different. What this plugin does is modulo functions, but on the end of modulo expression, the value is added by 1. Essentially useful for gradient map preparation, and that's the main reason why this exist. It can also be used for glitch art. Plugin Download - Image Modulo Toolkit.zip - ( Added new features in 10/09/2020 - Clipboard, Invert ) After you install the plugin, it's under Adjustments menu.

  4. This plugin allows to you adjust the saturation of the red, green and blue colors each one separately. You can find this effect in Adjustments menu. SaturationRGB.zip (Previously downloads: 496) Examples of the plugin work: @ingwer has made amazing video about use of this effect. See the topic CodeLab - First Steps (Saturation RGB) for information about how to create this effect. I hope this effect will be applied in your work.
  5. 'Color Matrix' Adjustment Plugin Summary Adjusts all individual pixels in the selected area of the active layer using a color transformation matrix. The plugin contains a set of predefined matrices to manipulate the individual RGBA channels, adapt transparency or to simulate the effect of different color blindness defects. Changing the matrix will show 'User defined' in the preset selector. Here the list of presets: Identity - Does nothing RGB (solid) - Sets the alpha channel to solid RGB (inverted) - Inverts the RGB chan

  7. Two Tone Threshold Found under: Adjustments .dll name = TwoToneThreshold Two Tone Threshold is an Adjustment which assesses the tones in an image and apportions two colours between the thresholds. In other words it turns colour images into black & white! ... or set your Primary and Secondary colours to something more lurid! ... or Primary color and alpha etc etc. It's in my updated plugin pack Red ochre v10 plugin pack As with all plugins - try it, if you like it, keep it - if not, uninstall it! There are many other plugins with a similar function but I want
  8. I was adjusting some photographs the other day and kept having to toggle between the Brightness/Contrast adjustment and the Hue/Saturation/Lightness adjustment to get just the right colors. So... I combined all of the most common adjustments onto one screen: Then, I bundled in my Black and White+ plugin. NO MORE TOGGLING! Until I add this to my pack, download here: CombinedAdjustments.zip Install the normal way, unzip the download to your desktop and run the "Install" batch file. You'll find this in your Adjustments menu.
  9. Adjustments > Invert Anything This plugin allows you to invert a pretty wide variety of things all in one plugin. I'm 99% sure most of this exists elsewhere, but there are a couple things that don't exist yet. Red/Green/Blue -- inverts the red, blue and/or green channels. Will essentially turn yellow into blue, red into cyan, and so on. Hue/Saturation/Value Inverts the hue, saturation or value. Alpha -- Inverts the alpha channel -- transparent pixels will become more opaque, and vice-versa. Fully transparent pixels will apparentl
  10. I've added an extra option which allows the post-effect Alpha values to be displayed as gray-scale colors. The intention is that this option would be ticked to allow the result of the effect to be easily assessed - and then untick before clicking OK. 32495_741da9c1d40fae38dc1154c962507162.Zip
  11. Adjustments > Remove Black This is a simple little plugin that turns black pixels into transparent pixels, then turns other pixels into alpha versions of themselves depending on their darkness so the effect is smoother. I apologize if this exists elsewhere -- the code is really really simple so I bet someone else has run across it. I doubt they have my threshold slider though. Threshold -- changes the amount of pixels that get alpha adjustments applied to them. Lower settings will have more of the image turning into alpha, higher settings will have
  12. Download from my plugin set Tutorial by forum moderator David Atwell: The Wonderful World of Gradient Mapping Get some nice gradients here: Presets for Gradient Mapping by ReMake This adjustment appears in the Adjustments menu. Amazing! Adjustments > Gradient Mapping Use this plugin to create a custom gradient and map it to your image based on any supported input channel. One of the primary uses of this plugin is to create a multi-colored gradient. Just use Paint.NET's built-in gradient tools to draw the gradient shape you want, then
  13. Plugin: TransparentToTransparentWhite.zip This is a trivial but sometimes useful adjustment that converts all transparent pixels to transparent white. I already had a plugin to convert transparent pixels to transparent black, but for those who only want to make all the transparent pixels the same color, transparent white may be preferable, since that's Paint.NET's usual transparent color. For example, it's the color used for Erase Selection.
  14. This plugin is all about "dimming" a certain channel, which means desaturating the highest-saturation pixels first and working its way down smoothly. There are also other RGB adjustment algorithms that add fine adjustment. First, let's look at the menu. ((NOTE)): Default settings should have all X-axis's set to 1.00. This makes the image appear as itself. Apologies, since I'm dealing with limitations in Codelab here. Red -- X axis -- Adjusts the red channel according to the "dimmer" algorithm. Red -- Y axis -- Adjusts the red channel according to a standard "levels" type algorithm. Gree
  15. Black and White+ version 1.1 Black and White+ includes 3 different algorithms to convert a color image into a black-and-white image. Luminosity Method Shade of Gray = 0.299 * Red + 0.587 * Green + 0.114 * Blue This is the default method. This is how the built-in Black-and-White effect converts a color image to black-and-white. This method gives different weights to Red, Green, and Blue. Other methods treat each color equally. Average Method Shade of Gray = (Red + Green + Blue) / 3 Lightness Method Shade of Gray = [Max(Red,Gre
  16. I know, very specific. This was made for a request I got from my friend ugng. He told me to publish it here in case some random dude comes up and wants to use this for whatever reason. Anyway! Posterize Alpha Limits the amount of steps in an alpha channel. Like posterize but for alpha channel Enjoy this spicy gif I made. Does this gif work? It doesn't work in the post preview. Hopefully it does. Love you all! UPDATE: added icon made by ugng alphalevels.dll
  17. Black and White+ is a simple plugin to convert an image to black and white. The primary additional option (that may or may not merit the "+") is the ability to specify the weights for each color channel. It's in the Adjustment menu. The plugin: The Help Menu description: Black and White+ converts a color image to a grayscale (or two-color) image. The controls are: Red Weight: The weight for the red channel when converting from color to brightness. Green Weight: The weight for the green channel when converting from color to brightness. Bl
  18. Download from my plugin set Get some really cool presets by ssaamm: http://forums.getpaint.net/index.php?/topic/21783-vintage-effect-pack-for-curves/ Here's what Rick Brewster has to say on the matter: Paint.NET Plugin spotlight: Curves+ This adjustment appears in the Adjustments menu. Amazing! Adjustments > Curves+ Curves+ is exactly like the Curves adjustment that comes with Paint.NET. OK, not really. It is actually far more powerful. Enjoy Download from my plugin set For developers:Curves+ is on
  19. This is my first plugin and though it's pretty basic (and might have been done before), I think it's useful. Essentially it takes a black and white image and converts it to a "black and transparent" image. The whole point is that if you have a sketch, applying this plugin will make all of the white parts transparent so that you can color it, add a background, whatever.

  20. Transparent to Transparent Black is an utterly trivial Adjustment that changes all the transparent pixels to transparent black (0, 0, 0, 0). It can sometimes be useful, particularly when using the Texture Merger. DLL, Version 1.0: TransparentToTransparentBlack.zip The code:
  21. Overview This plugin lets you change the RGB, HSV, or alpha channel of the image. It replaces my old Saturation to Alpha plugin and a lot of other users' channel-manipulating plugins. After choosing a channel to manipulate, you can perform arithmetic operations, inversion, channel swapping, contrast and truncation. Located in the Adjustments tab. Purpose and Application I find this useful mainly to set the alpha of an image and colorize a grayscale image, since you can't color a grayscale image using the Hue/Saturation tool if it has 0 saturation. Truncation makes a nea
  22. SubLCD This is a usability update of @xrl's original SubLCD resize plugin. See changelog below. Adjustments -> SubLCD Features Example Images Before (Actual and Zoomed-in) After (Actual and Zoomed-in) Changelog v1.2 by toe_head2001 (Jan 9, 2016) Fixed: Now works properly on selections (for real this time).

  23. Due to a request here: http://forums.getpaint.net/index.php?/topic/111023-need-color-temperature-control-equivalent-to-windows-live-photo-gallery/ I created a Temperature / Tint Adjustment plugin. It is found under the Adjustment menu.

  24. Overview Color Replacer can convert pixels in the current selection from one color to another. Pixels with colors that almost match (based on a % match called tolerance) will be affected too, but the original color will be mixed with the new color. It is located under the Adjustments tab. Purpose and Application Use this plugin to remove backgrounds that are close to being single colors. Affected color: The color that you want to change. New color: The new color to choose. Affected color transparency: The transpar
  25. This plugin allows you to modify multiple channels of an image in various ways. Once installed, it can be found in the Adjustments menu, since it is more of an adjustment utility than an effect. Basics - How the Plugin Works In the plugin's dialog, you can configure multiple channel modifications. Each modification allows you to manipulate one channel of the image with one of the built in operations. Every operation uses one or more arguments to calculate the new value for the target channel. The number, form and usage of those arguments depends on the chosen operation. The mo
