Warpaint

Warpaint (codename) is a pixel-art-oriented image editor written in rust.

Online demo

There's an online demo: https://wareya.github.io/warpainter/

It might not work in some browsers and it's a little glitchy. Also, remember that Warpaint is extremely immature and can't be used for complex art yet. The online demo might also go down if there's a problem with the continuous integration system.

Features / TODO

I expect to have all of the following features. This is sorted in order of development priority, not general importance.

tools

• pencil tool (with proper edit and commit phases)
• fill tool
• eraser tool
• eyedropper tool
• line tool
• other shape tools (rectangle, circle, polyline, arrow line, etc. with outline/stroke and non-fill variants)
• selection tool (arbitrary alpha-mask-based selections, not shape-based selections)
• move tool
• deselection
• tool-specific undo (selection changes, transient move operations)
• transform tool (bilinear transform, not perspective transform)

layer management stuff

• layers
• layer creation/deletion
• layer groups (implemented but not hooked up)
• layer moving (by buttons)
• layer moving (by drag and drop)
• layer merging/flattening/duplication
• effect layers (blur, levels, curves, etc)
• layer effects (outline, glow, recolor, etc)
• real layer widget with a context menu, visibility button, etc
• layer multiselection (with a main layer selection still)
• copy/paste

other layer stuff

• photoshop blend modes
• layer masks
• layer clipping
• alpha lock
• layer lock

ui

• basic grid
• rgb and alpha sliders for the color picker
• view transformation (scale, pan, rotation)
• preview panel like clip studio paint and photoshop's navigator panel
• custom preview windows with a scripting language, for things like tilesets, animations, etc

etc

• undo/redo (!!!!important!!!!) (implement via layer stack analysis + dirty flags/rects)
• implement undo/redo for more actions (selections, layer stack manipulations, etc)
• file creation menu
• opening and saving images (at least i think I remembered to do this...?)
• opening and saving project files (use sqlite?)

low priority

• flag to do processing in unclamped linear rgb instead of clamped sRGB
• project tabs
• view mirroring
• advanced grids (three levels, non-square, support for non-axis-aligned grids)
• custom blend modes with a scripting language
• option to save the undo/redo buffer to project files (for timelapses)
• symmetry tool
