paint.c plugins 1.0.0

Ten optional effect plugins for paint.c, the
native C17 editor with the Paint.NET 5.1 workflow. Each one is a native,
independent re-creation of a popular Paint.NET plugin, made from its public
description (forum posts, help text, screenshots), or ported from source
its author published under a permissive license. Credit for the designs
goes to the original authors, named below and in each plugin's README.md.
These plugins are not affiliated with or endorsed by dotPDN LLC or the
original plugin authors; Paint.NET's own .NET plugins cannot be loaded by
paint.c.

Requires paint.c 0.1.1 or later; on 0.1.0 Align Object falls back to a
drop-down and effect notices are not shown.

The plugins

Plugin Menu What it does Original design and author Basis Download
AA's Assistant Effects > Object > AA's Assistant Smooths the jagged edge of a cut-out object so it blends into any background, and doubles as a simple alpha curve. AA's Assistant by dpy, after an idea by Boude (original) clean room re-creation Linux / Windows
Align Object Effects > Object > Align Object Moves the object on a transparent layer to an edge, a corner or the center of the canvas or the selection. Align Object by xod, helped by MJW (original) clean room re-creation Linux / Windows
Bevel Object Effects > Object > Bevel Object Gives an object on a transparent layer, or a selection, a raised and lit bevelled edge with an optional drop shadow. Bevel Object and Bevel Selection by BoltBait (Bevel Selection with Ed Harvey) (original) clean room re-creation Linux / Windows
Content Aware Fill Effects > Selection > Content Aware Fill Removes an object or a blemish by filling the selection with texture synthesized from its surroundings. Content Aware Fill by null54, after Resynthesizer by Lloyd Konneker and the research of Paul Harrison (original) clean room re-creation Linux / Windows
Gradient Mapping Adjustments > Gradient Mapping Recolors an image by looking up each pixel's luminosity, color channel, hue, saturation or alpha in a multi-color gradient. Gradient Mapping by pyrochild (Zach Walker) (original) port of the MIT source (LICENSE-original.txt in the zip) Linux / Windows
Grid / Checkerboard Effects > Render > Grid / Checkerboard Draws a grid of lines, a checkerboard or a grid of dots with any cell size, line width and two colors with alpha. Grid Maker by BoltBait and Illnab1024, and Grid & Checker Maker by MadJik (original) clean room re-creation Linux / Windows
Grim Color Reaper Effects > Color > Grim Color Reaper Removes a background color and recovers what was blended with it, so soft edges, glows and shadows become partly transparent without a halo. Grim Color Reaper by Jotaf, continued as Kill Color Keeper by Pratyush (original) clean room re-creation Linux / Windows
Perspective Effects > Distort > Perspective Keystone and perspective transforms set by three ratios, vertical or horizontal, as a true perspective or a plain trapezoid. Perspective by dpy (original) clean room re-creation Linux / Windows
Shape3D Effects > Render > Shape3D Wraps the image around a 3D sphere, cylinder or box and renders it with a perspective camera, lighting and a highlight. Shape3D by MKT, with later fixes by MJW and toe_head2001 (original) clean room re-creation Linux / Windows
Water Reflection Effects > Distort > Water Reflection Turns the lower part of the selection into a rippled mirror image of what is above a waterline, like a lake reflecting a skyline. Water Reflection by MadJik, after a reflection script by Tom Jackson (original) clean room re-creation Linux / Windows

All ten in one zip per system:
paintc-plugins-all-1.0.0-linux-x86_64.zip,
paintc-plugins-all-1.0.0-windows-x64.zip.

Every zip holds one top folder per plugin with the library, its README.md
(controls, credits), a screenshot and, for ported code, the original
license as LICENSE-original.txt.

Installing

Unzip into the plugins folder of your system (create it if it is missing),
so that each plugin ends up as .../plugins/<name>/<name>.so (.dll), then
restart paint.c. The effects appear in the menus listed above; their
tooltip names the plugin, its author and version.

System Download Plugins folder
Linux x86_64 (glibc 2.31 or newer, the same systems as the AppImage) *-linux-x86_64.zip ~/.local/share/paintc/plugins/ ($XDG_DATA_HOME/paintc/plugins/ when that is set)
Windows 10 and 11 x64 *-windows-x64.zip %APPDATA%\paintc\plugins\, or a plugins folder next to paintc.exe of the portable zip
macOS not in this release build them from source: docs/PLUGINS.md 
# Linux, all plugins
mkdir -p ~/.local/share/paintc/plugins
unzip paintc-plugins-all-1.0.0-linux-x86_64.zip -d ~/.local/share/paintc/plugins
# Windows (PowerShell), all plugins
Expand-Archive paintc-plugins-all-1.0.0-windows-x64.zip "$env:APPDATA\paintc\plugins"

Effects > Plugin Errors... lists any library paint.c could not load;
paintc --disable-plugins starts without plugins; delete a plugin's folder
to remove it. Plugins run inside paint.c with the program's rights: install
plugins only from sources you trust. More: docs/PLUGINS.md in the source.

How they were built and checked

  • Built from commit cfb505e with
    packaging/plugins/build-plugins.sh: Linux in the Ubuntu 20.04 container
    of the AppImage (GCC 13), Windows cross built with mingw-w64 (UCRT).
    Every library exports fx_entry; the Linux ones need no glibc symbol
    newer than 2.31 and only glibc libraries, the Windows ones import only
    KERNEL32 and the C runtime. The zips are reproducible.
  • Load tested with the paint.c 0.1.1 release builds: the Linux zips (each
    zip, then the all-plugins zip) with the AppImage on X11, the Windows zips
    with the installed paintc.exe under Wine: all ten plugins loaded with
    no Plugin Errors entry, and every effect opened its dialog and applied
    (one History item each).

The plugins are MIT licensed like paint.c. Gradient Mapping is ported from
the MIT-licensed source of pyrochild's plugin; its license ships with it as
LICENSE-original.txt. The other nine were written from the public
descriptions of the originals, without their code.
