Paint.NETè un software gratuito per l'editing di immagini e foto progettato per computer che eseguono Windows. Offre un'interfaccia pulita e intuitiva che consente agli utenti di imparare rapidamente e iniziare a modificare le immagini con facilità. Originariamente sviluppato come progetto universitario, è diventato un'applicazione ben mantenuta e rispettata supportata da una forte comunità online.

Paint.NETsupporta i livelli, consentendo agli utenti di gestire composizioni complesse con precisione. Le funzioni di modifica standard come il ritaglio, il ridimensionamento e la rotazione sono disponibili, insieme a capacità più avanzate come le regolazioni delle curve, le modalità di fusione e una varietà di effetti artistici. Questi strumenti aiutano gli utenti a migliorare le foto o creare opere d'arte digitali in modo efficiente.

Paint.NETsupporta una vasta gamma di formati immagine, inclusi JPEG, PNG, BMP e persino file PSD di Photoshop con plugin. Il suo sistema di plugin consente agli utenti di espandere le funzionalità aggiungendo nuovi effetti, regolazioni e tipi di file, rendendolo adattabile a diversi flussi di lavoro creativi.

La comunità dietroPaint.NETsviluppa attivamente tutorial, plugin ed estensioni, contribuendo al continuo miglioramento del software. Con aggiornamenti regolari e un'installazione leggera, fornisce un'esperienza di modifica reattiva senza richiedere requisiti hardware elevati.aint.NETè una scelta solida per chi cerca un editor di immagini affidabile e semplice.

• Effetti speciali: Offre effetti come sfocatura, nitidezza, rimozione degli occhi rossi, distorsione e embossing.
• Unlimited History: Annulla illimitato con una finestra della cronologia visiva per il recupero degli errori.
• Supporto Plugin: Estendi la funzionalità con plugin creati dalla community per filtri, effetti e strumenti.
• Community Attiva: Accedi a tutorial, download di plugin e supporto tramite un ampio forum utenti.
• Prestazioni veloci: Ottimizzato per velocità e prestazioni anche su hardware modesto.
• Aggiornamenti regolari: aggiornamenti frequenti con correzioni di bug, nuove funzionalità e miglioramenti.

• Windows 7 SP1 or newer is now required.
• NET Framework 4.5 is now required, and will be installed if needed.
• A dual-core (or more!) processor is highly recommended.
• Hardware acceleration (GPU) via Direct2D is now supported.
• Please disable this in the Settings dialog if you experience visual artifacts.

• A brand new, asynchronous, fully multithreaded rendering engine allows performance to scale very well with respect to the number of CPU cores whether you have 2, 4, 6, or even 16 of them.
• The responsiveness of the user interface has been greatly improved, especially when working with large images.
• Memory usage is lower.
• Improved battery life impact due to fixing the way the floating windows manage their transparency.
• Startup performance when many plugins are installed is improved, thanks to the Multicore JIT feature introduced in .NET 4.5.

• Selections are now antialiased, which greatly improves the quality around the edges of selected content. You can turn this on and off at any time from the toolbar.
• Everything related to selections now has much higher performance and greatly reduced CPU usage, especially if hardware acceleration (GPU) is enabled.
• The selection outline is now rendered using the “dancing ants” animation, which greatly improves the contrast between it and the image itself.

• The functionality previously provided by the Utilities, Window, and Help menus has been simplified, consolidated, and moved to the top-right corner of the main window.
• The image thumbnail list has been moved up 1 row so that it no longer intrudes into the current Tool’s toolbar space. This means it will no longer “jump around” when you switch between tools. This also means that it is aligned to the top of the monitor when the main window is maximized, making it easier to click on images (Fitt's Law)
• The image thumbnail list can now be reordered with drag-and-drop.
• The zoom slider and units selector have been moved from the toolbar to the bottom right corner of the window (into the status bar).
• Layers can now be reordered with drag-and-drop.
• Improved quality of Image->Resize.
• Copying to the clipboard now includes the “PNG” format, which allows transparency to survive from many popular applications (e.g. Office)
• Shift+Backspace will now fill the selection with the secondary color (Backspace, the shortcut key for Edit -> Fill Selection, still fills with primary color as usual).
• EXIF rotation metadata is now applied when opening images (e.g. JPG taken with a rotated camera).
• Crash logs are now stored in%LOCALAPPDATA%\paint.net\CrashLogs (e.g. C:\Users\username\AppData\Local\paint.net\CrashLogs) instead of on the desktop.

• Drawing tools (Pencil, Paintbrush, Eraser, Clone Stamp, Recolor) now have much smoother mouse input handling via GetMouseMovePointsEx.
• Brush tools (Paintbrush, Eraser, Clone Stamp, Recolor) now have soft brushes support via a “Hardness” setting in the toolbar.
• The Move tools (Move Selected Pixels, Move Selection) have a much better UI for scaling, moving, and (especially) rotation.
• The Move tools now support moving the rotation anchor, which changes the center of rotation.
• The new Shapes tool replaces the Rectangle, Rounded Rectangle, Ellipse, and Freeform shape tools. 27 shapes are currently available. You may move, resize, and rotate a shape, as well as reconfigure any other properties from the toolbar (color, outline size, etc.) before committing it to the layer.
• Color Picker has a configurable sampling radius, and can sample from either the current layer or the whole image.
• Gradient tool now supports a new Spiral gradient type and allows configuration of the repeat mode (none, repeat, wrapped).
• Gradient tool has improved rendering quality via dithering and antialiasing. You can control both of these with the standard antialiasing toggle in the toolbar.
• Magic Wand and Paint Bucket now allow live adjustment of Tolerance and the Origin (click location) after clicking (press Enter to commit/finish).
• Magic Wand and Paint Bucket can now sample from either the current layer or the whole image.
• Paint Bucket tool now supports anti-aliasing.
• Recolor tool can now use the color of the pixel where you click as the color to be replaced. Or, as usual, it can use the secondary color.
• Text tool now supports multiple rendering modes: Smooth, Sharp (Modern), and Sharp (Classic). These correspond to DirectWrite rendering modes of Outline, ClearType Natural Symmetric, and GDI Classic, respectively.
• Text tool now supports colored fonts on Windows 8.1.
