Namespace Drawing

The Drawing namespace provides visual styling, color management, and drawing primitives for Terminal.Gui.

Key Types

• Attribute - Foreground/background color and text style combination
• Color - Terminal colors including TrueColor (24-bit) support
• KittyGraphicsEncoder - Encodes Color[,] pixels as Kitty graphics APC sequences
• KittyGraphicsSupportDetector - Detects Kitty-compatible terminals and their cell pixel resolution
• KittyGraphicsSupportResult - Reports Kitty graphics availability and resolution
• Scheme - Maps semantic visual roles to attributes
• SixelEncoder - Encodes Color[,] pixels as Sixel DCS sequences
• SixelSupportDetector / SixelSupportResult - Detect Sixel availability, palette limits, transparency support, and resolution
• LineCanvas - Line drawing with automatic glyph joining
• Thickness - Border and spacing dimensions
• Glyphs - Standard drawing characters for UI elements

Color Support

// Named colors
Color red = Color.Red;

// TrueColor (24-bit RGB)
Color custom = new (128, 64, 255);

// Create an attribute
Attribute attr = new (Color.White, Color.Blue);

Raster Graphics

ImageView and the driver output layer use Drawing encoders and support detectors to render raster images. Kitty graphics is preferred when available; Sixel is the fallback for terminals that support Sixel but not Kitty. Terminals that support neither protocol render ImageView content with colored cells.

Scheme System

Schemes map semantic roles to visual attributes:
