OmaPhoto

OmaPhoto is a layered image editor for Linux, made first for Omarchy. It follows your Omarchy theme and switches with it.

It is a Linux port of Compositor by Wonder Assembly, a macOS app written in Swift. Compositor's source is the specification: OmaPhoto keeps its tools, its menus and its shortcuts (Ctrl for ⌘, Alt for ⌥). It reads and writes Compositor's .comp projects, so a project moves between the two apps. OmaPhoto is independent of Wonder Assembly.

What it does

*Layers, folders, masks, clipping masks, blend modes and opacity

• Selections: marquee, lasso, magic wand, load from a layer, expand and contract *Brush, eraser, spot healing, clone stamp, smudge, blur and liquify, gradient, shapes, type *Move, transform and distort layers and selections *Levels, Curves, Hue/Saturation, Exposure, Gradient Map and Grain, as edits or as adjustment layers *Layer effects: stroke, drop shadow, color overlay, inner shadow *Filters: Gaussian and motion blur, noise, lens correction, Content-Aware Fill and Remove Background (U²-Net on ONNX Runtime, offline) *Crop, canvas size, image size; PNG and JPEG export *Imports JPEG, PNG, TIFF, HEIC, Photoshop files and camera RAW *Drag a number's label to scrub its value *Keep working while a project saves *A project another app changes on disk reloads in place; unsaved work is never replaced without asking

Works with AI agents

AI agents and scripts can build and edit projects directly: a .comp is a folder of PNG layers and a manifest, and an open project updates live as it's written. See Writing OmaPhoto projects and the project format.
