Kitty graphics: transmit
The transmit action (
a=t) sends image data to the terminal for storage without displaying it. The terminal assigns an image ID and acknowledges receipt. This is the foundation of the kitty graphics protocol — images are transmitted once and can be displayed multiple times at different positions.How this is tested: Transmit a 1x1 PNG with
a=t and a unique image ID. Check for acknowledgment response (APC G ... ST).Analysis2026-03-29
