SixelEncoder

Namespace: Hex1b.Surfaces

Assembly: Hex1b.dll

Encodes pixel data to Sixel graphics format.

public static class SixelEncoder

Inheritance

Object → SixelEncoder

Methods

Encode(byte[], int, int)

Encodes raw RGBA byte array to sixel.

Parameters:

• rgbaPixels (Byte[]): RGBA pixel data (4 bytes per pixel).
• width (Int32): Image width in pixels.
• height (Int32): Image height in pixels.

Returns: String

The sixel-encoded string.

public static string Encode(byte[] rgbaPixels, int width, int height)

Encode(SixelPixelBuffer)

Encodes a pixel buffer to a sixel payload string.

Parameters:

• buffer (SixelPixelBuffer): The pixel buffer to encode.

Returns: String

The sixel-encoded string (DCS ... ST format).

public static string Encode(SixelPixelBuffer buffer)

Fields

MaxPaletteColors

Maximum number of colors in the sixel palette.

Returns: Int32

public const int MaxPaletteColors = 256

Remarks

Sixel is a bitmap graphics format used by terminals. Each "sixel" character encodes a 1×6 pixel column. This encoder takes RGBA pixel data and produces a sixel payload string that can be embedded in terminal output.

The encoder handles: Color palette quantization (max 256 colors)Transparency (transparent pixels are not drawn)Run-length encoding for compression
