ImageProtocol enum

Namespace: Arlecchino.Rendering.Terminals · Assembly: Arlecchino.Core

How a picture reaches the terminal. Like GraphSymbols, this is a question of what the terminal can do rather than of taste.

public enum ImageProtocol

Fields

Name	Value	Summary
Blocks	0	Cells, two pixels to each: the color of the upper half block and the background behind it. It needs nothing of the terminal beyond color and goes through the ordinary frame diff.
Kitty	1	The kitty graphics protocol: the pixels themselves, spoken by kitty, WezTerm and Ghostty. A terminal that does not speak it shows the escape sequence as text.
Sixel	2	Sixel: the older protocol, spoken by Windows Terminal, xterm, foot and WezTerm. Color comes down to a cube of 216, and Glyphs.CellWidth says how large a cell is taken to be.
Auto	3	The best of what the terminal admitted to when TerminalProbe.Ask asked, preferring kitty over sixel, and ImageProtocol.Blocks when it admitted to nothing. It is the default.
