Inheritance

Object → SixelDecoder

Methods

Decode(string, int, int)

Decodes a Sixel DCS payload to raw RGBA pixel data.

Parameters:

• payload (String): The Sixel payload (including or excluding DCS wrapper).
• cellWidth (Int32): The width of a terminal cell in pixels.
• cellHeight (Int32): The height of a terminal cell in pixels.

Returns: SixelImage

Decoded image with RGBA pixel data, or null if decoding fails.

Remarks

Sixel is a graphics format where each "sixel" represents a column of 6 vertical pixels. The data includes a color palette definition followed by sixel character data.

This decoder is used to convert sixel data embedded in terminal snapshots into images that can be embedded in SVG output for visual testing.
