## Description

lsix is a command line image viewer and renderer that displays image files as a grid of thumbnails directly within a terminal emulator using Sixel graphics. It functions as a visual file browser and montage tool, converting bitmaps and vector formats into Sixel-encoded graphics for shell-based display.

The tool extracts individual frames from multi-frame animated files to display them as a grid of static thumbnails. It also converts non-raster formats, such as SVG and PDF, into viewable bitmap previews.

To ensure visual consistency, the utility queries the terminal for active foreground and background color values. This allows it to perform alpha-channel color blending, ensuring transparent images integrate naturally with the terminal's current color palette.
