pittore_studio

Descrizione

A layer-based photo editor for Linux. Raster painting and retouching, vector shapes and paths, type, adjustment layers, filters, and an ICC-aware colour pipeline, written in C++20 on Qt 6.

Rendering goes through the GPU when you have an NVIDIA or AMD card and falls back to a CPU path when you don't. Both backends implement the same kernels, and the test suite checks that they agree.

Status: alpha. The engine and the test suite are in decent shape; the interface still moves around and you should expect rough edges. Linux only — the build refuses to configure anywhere else. Features: * Layer documents with groups, masks, clipping, adjustment layers and a full undo history, saved in a single-file .psc project format (legacy .ifp still opens). * 135 filters in 17 categories, 15 adjustment kinds, 28 blend modes, and layer styles (shadow, glow, overlay, stroke, bevel, blur). * Selection, retouching and painting tooling: marquees, lasso and magic wand, object selection, clone and healing brushes, patch, content-aware move, liquify, mixer and history brushes, dodge/burn/sponge. * Vector persona: pen tools, boolean path operations, around 40 parametric shapes, SVG import and export, QR codes. * Four personas — Pixel, Vector, Draw, Color — each with its own tool set and options bar. * Text built on HarfBuzz shaping and FreeType rasterization, with character and paragraph panels and type masks. * Colour management through Little CMS: ICC profiles on import, CMYK conversion, soft proofing, and a mismatch policy when a file's profile disagrees with the working space. * Optional AI background removal, object selection and refinement. The models are downloaded on demand, never bundled.
