About:
Terminal Image Viewer (tiv) is a high-performance tool that displays images directly in the terminal using Unicode block characters. It utilizes the C++ Standard Library and image processing libraries to sample pixel data and render it as text-based graphics. This allows developers to preview visual assets or inspect data without leaving the command line.
Key Features:
  • High-performance C++ implementation for fast rendering
  • Supports multiple image formats (JPEG, PNG, WebP, etc.)
  • Automatic scaling to fit terminal window dimensions
  • Uses Unicode block characters for high-density output
Use Cases:
  • Previewing images within CLI file managers or terminal sessions
  • Debugging computer vision scripts by visualizing output directly
  • Displaying QR codes or visual data in automated terminal reports
Alternatives:
  • chafa – Chafa is a highly optimized alternative that often supports true color and animation better.
  • imgcat – imgcat is a native feature in iTerm2 that renders images using terminal protocols rather than text characters.
